Troubleshooting MacOS Catalina problems

Some Mac users have reported a variety of problems with MacOS Catalina, ranging from installations getting stuck or taking abnormally long, to problems with some apps not working, to issues with certain printers or accessories no longer working, App Store difficulties, iCloud and Apple ID issues, amongst other nuisances.

While installing and using MacOS Catalina goes fine for most users, that is no solace if you are experiencing problems with a particular Mac and the new MacOS 10.15 release. Below we will discuss a variety of reported issues and problems with MacOS Catalina, and offer various troubleshooting methods to attempt to resolve those difficulties.

Before perusing this guide or attempting any troubleshooting method, be sure to back up your Mac and all data first. Failure to backup data can result in permanent data loss.

MacOS Catalina Won’t Download or Shows “An error occurred while running scripts from the package “RecoveryHDMetaDmg.pkg”

If you are attempting to download MacOS Catalina and it fails with a “An error occurred while running scripts from the package “RecoveryHDMetaDmg.pkg” error message, it may be related to third party firewall, anti-virus, or anti-malware software running on the Mac.

Temporarily disable the third party software that is a firewall, anti-virus, or anti-malware protection, and then relaunch System Preferences to check for the download again and MacOS Catalina should arrive as expected.

Note that some Macs may need to be restarted after third party protection software is disabled, depending on the software and how it works. In that case, after rebooting the Mac return to System Preferences in the Software Update section to download MacOS Catalina as expected.

MacOS Catalina won’t install because “There is not enough free space on Macintosh HD to install”

If you do not have sufficient free disk space available on the Mac hard drive, you will not be able to install MacOS Catalina.

Aim to have at least 15GB freely available to complete the installation of MacOS Catalina.

MacOS Catalina Installation Stalls on “Estimating time remaining…”

A fair number of people have reported that MacOS Catalina installation takes longer to install than they were expecting, or longer to install than prior MacOS installations. A common symptom of this is the Mac is apparently stuck on “Estimating time remaining…” when trying to install MacOS Catalina.

If you see the “Estimating time remaining…” screen when trying to install MacOS Catalina, be patient. It’s unlikely the installer is actually stuck, so just let it sit, and if it’s a MacBook Pro or Air make sure it is connected to a power source.

Let the Mac sit for however long it takes to complete the installation of Catalina, it may take several hours. The Mac will automatically boot into MacOS Catalina when finished installing.

There are mixed reports that the MacOS Catalina installation has taken anywhere from 45 minutes to over 12 hours to complete, how long it takes on a particular machine likely depends on many factors, including computer speed, internet connection speed, the Mac OS version being updated from, and more, thus it’s best to initiate the installation when there is plenty of time available to allow the Mac to complete installation.

MacOS Catalina Installation Stuck on “Less than one minute remaining”

Some users report that installing MacOS Catalina gets stuck on a black screen with an  Apple logo and progress bar, stating there is less than a minute remaining to complete the installation.

If you see this screen, let the Mac sit and wait for a substantial amount of time before attempting to intervene.

If the Mac is still stuck on “Less than one minute remaining” after many hours (let it sit overnight if you can), and you have a full backup of your data, try powering down the Mac and then turning it back on again. It may boot directly into the MacOS Catalina setup screen. It also may fail to boot entirely, in which case you’ll need to reinstall MacOS system software with Internet Recovery (you can also try to reinstall MacOS Mojave through regular recovery too), or restore the Mac from a previously made Time Machine backup.

MacOS Catalina Installation Stuck or Fails with “The operation couldn’t be completed. (PKDownloadError error 8.)”

This error has been reported to occur during installation of MacOS Catalina if the internet connection is disrupted or disconnected.

Insure that the Mac has an active wi-fi or ethernet connection and that the internet works as expected, and then try installing MacOS Catalina again.

MacOS Catalina Stuck on “Setting Up Your Mac” Screen After Install

Let it sit for at least several hours, it may resolve itself.

If a after hours pass, force reboot the Mac by turning the computer off, then turning it back on again

Mac Running MacOS Catalina Randomly Crashes & Restarts

Some Mac users are reporting their Mac is crashing and restarting itself, particular when the Mac is left unattended for a period of time.

This random crash/freezing/restarting issue appears to happen more often on newer Macs with T2 security chips, or with Macs with a Radeon Pro Vega GPU, but it has been reported on other Mac models as well.

There are various discussion threads on Apple Support Forums here about this, but there is not yet any clear explanation or solution to this problem.

Reinstalling MacOS Catalina may help.

If any updates come available to MacOS Catalina, be sure to install those right way (ie: MacOS Catalina 10.15.1, 10.15.2, etc), as they may resolve the problem.

Downgrading to MacOS Mojave may also be a workaround to some users, though that is obviously not desirable or practical for many users.

Frequent “Update Apple ID Settings” Requests

Some users have reported a frequent “Update Apple ID Settings” pop-up message, informing them that some services will not be available until they sign-in again. Then after signing in again, the popup returns.

Update Apple ID settings in Mac OS Catalina message

If you encounter frequent “Update Apple ID Settings” alerts, first try restarting the Mac.

If the “Update Apple ID Settings” alert message continues still, back up the Mac (if you haven’t done so already), then go to System Preferences and logging out of the Apple ID, rebooting the Mac, then logging back in again.

Be aware that signing out of an Apple ID may cause issues with synced data over iCloud, including iCloud Documents, iCloud Files, iCloud Photos, and other iCloud syncing.

Persistent iCloud Password Requests

Some users have reported issues with persistent Apple ID and iCloud password requests.

Open System Preferences > go to iCloud settings > and login to iCloud directly.

You may also need to log out and then log back into iCloud via System Preferences, but be aware that doing so can cause issues with iCloud Documents, iCloud Files, and other iCloud syncing.

Seeing Constant iCloud Terms & Conditions Agreement Loop in MacOS Catalina

Some users are reporting a constant loop of seeing iCloud Terms & Conditions that won’t be dismissed or agreed despite interacting with it.

Go to System Preferences > Internet Accounts > choose the Apple ID that is used for the App Store and other purchases, and then agree to the Terms & Conditions that appear on this screen.

Some Mac Apps Don’t Work, “App Needs to be Updated” Error Message

Any 32-bit app that has not been updated to 64-bit will not work in MacOS Catalina.

When attempting to launch an app that does not work in MacOS Catalina, you will see an error message stating “(Name) needs to be updated”

App Needs to be Updated MacOS Catalina error message

This includes many older versions of popular apps like Microsoft Office (Word, Excel, Powerpoint, etc), Adobe Photoshop, Lightroom, and many smaller third party tools and utilities.

Additionally, many popular older Mac games are 32-bit and thus will not work on MacOS Catalina (unless they are updated for 64-bit support, which some developers have already stated will not happen with older software).

The only solution to this is to update the apps to 64-bit versions, or to find alternative applications. Or, more extreme, would be to downgrade from MacOS Catalina, but that’s a sizable hassle.

Printers, Scanners, Accessories Incompatible or Don’t Work with MacOS Catalina

Some users have found that printers, scanners, and other hardware accessories are no longer working after updating to MacOS Catalina.

This may be related to the loss of 32-bit application support, as some older printers and drivers are not updated to 64-bit.

Numerous reports exist of various Brother, Epson, HP, and other printers and accessories are incompatible with MacOS Catalina currently.

A good first step would be to reach out to the manufacturer of the printer, scanner, or hardware accessory and see if new drivers or related software are available with MacOS Catalina compatibility.

If new Catalina compatible drivers are available, install them to regain access to the printer, scanner, or hardware accessory.

Mail Missing, Mail Data Loss After MacOS Catalina Update

Some users have reported mail is missing, or that parts of mail messages are incomplete, or some other form of Mail app data loss has occurred after updating to MacOS Catalina.

If you have a Time Machine backup from before updating to MacOS Catalina, you should be a able to restore the Mail folder from that backup. You can also access the backup mail data folder directly on the Time Machine backup, then from Mail app in MacOS Catalina, go to File > Import Mailboxes and import that back-up Mailfolder.

Wi-Fi Not Working in MacOS Catalina

Some users have reported wi-fi problems with MacOS Catalina. Often a solution for wi-fi not working is to go to System Preferences > Network > and create a new Network Location and to re-join a known working wi-fi network.

Bluetooth Input Lagging, Magic Trackpad Slow Response with MacOS Catalina

Some users have reported significant bluetooth input lag since updating to MacOS Catalina, where interacting with a Magic Trackpad or other Bluetooth device has a notable delay of sometimes several seconds before responding.

If you’re experiencing slow response from Bluetooth devices in MacOS Catalina, try disconnecting them from the Mac, removing them, and then reconnecting and resyncing the Bluetooth accessory to the Mac.

Unable to Connect to Network Drives / SMB Shares in Catalina

Some users have reported they are no longer able to connect to network shares with SMB file sharing. This may be an issue with NetBIOS, or it may be due to some other problem, depending on what exactly the network problem is.

You may be able to resolve network sharing issues for Guest users by going to System Preferences > Users & Groups > Guest User > and choosing “Allow guest users to connect to shared folders”

Loss of iTunes Causing Issues with Music Playlists

Some users have reported that music playlists created from iTunes are not being imported or included in the new Music app of MacOS Catalina.

This may be a bug, or it could be an issue with the Music app not finding the playlist files from iTunes.

Some users have reported that simply quitting Music app and restarting the Mac has allowed their old iTunes playlists to surface in Music app as expected.

Unable to Access TV Purchases & TV Content from TV App in Catalina

Some users have reported they are not able to access any content from the TV app in MacOS Catalina.

Some users are not able to stream their TV purchases and video content from the TV app, and some users are not able to download their purchases from TV app.

Symptoms of this issue are typically a gray ‘download from iCloud’ button showing but that is unresponsive, and no video content downloads or plays in the TV app on MacOS Catalina.

If you’re unable to access your purchases and content in TV app in MacOS Catalina, confirming that the appropriate Apple ID is logged into the Mac and TV app, then quitting the app and restarting the Mac may help.

iTunes Removal Causing Issues with XML File Support & Third Party Music Apps

Some users of various music apps have reported that MacOS Catalina does not work with various music production and DJ apps.

This is apparently due to an issue with XML file support being removed from the new Music app.

If you rely on an application which requires iTunes or iTunes XML file support, consider avoiding MacOS Catalina for the time being, or until the apps you rely on are updated to support MacOS Catalina.

You can read more about this specific issue at The Verge if interested.

Mac App Store Showing “No Purchases”

Some Mac users are discovering that MacOS Catalina is not showing their purchased app history.

Sometimes simply rebooting the Mac can resolve this problem.

Otherwise, try logging out of the Mac App Store, quitting the App Store application, relaunching the App Store, then logging back into the Mac App Store again, to regain access to purchases.

Mac App Store no purchases error message

Mac App Store Showing “No Updates”

Some users have reported that the Mac App Store is erroneously showing a “No Updates” available message, despite having older versions of apps like iMovie installed that are not working without an update for full 64-bit compatibility.

Quitting the Mac App Store, then rebooting the Mac and relaunching the Mac App Store appears to resolve this problem.

Mac is Hot and Running Slow After Installing MacOS Catalina

This is likely due to the system reindexing files on the drive, and the system toll it takes to perform maintenance tasks that are necessary after reinstalling or updating MacOS system software.

Let this process complete, it may take a while, but the Mac should perform as expected when that background activity has finished.

Safari Can’t Connect to Websites, But Internet Works

Some third party firewall software and anti-virus apps may be causing issues with Safari and other apps accessing websites and the internet in general.

Try disabling those third party firewall and virus tools, then rebooting the Mac to see if the issue is resolved.

MacOS Catalina Wi-Fi Dropping Connections

Adding a new Network Location often can resolve issues with dropping wi-fi connections.

Make sure you also have reasonable distance to the wi-fi router and there is no significant interference, which is good general advice or wi-fi connection issues.

Additional MacOS Catalina Troubleshooting Ideas

Depending on the issue, you may want to try a few additional troubleshooting steps like:

MacOS Catalina is Unusable for Me, Help!

If you find MacOS Catalina totally unusable for whatever reason, you have a few options:

  • Restore the Mac from a previously made Time Machine backup, which is perhaps the easiest and best method of reverting from MacOS Catalina
  • Reinstalling MacOS via Internet Recovery, which will attempt to reinstall the version of MacOS that came with the Mac
  • Erase the Mac and restore from Time Machine or a prior backup method to effectively downgrade from MacOS Catalina to the prior version of MacOS you had backed up
  • Contact official Apple Support for further assistance – Apple support techs and engineers may be able to resolve a problem for you that unaffiliated third party fan sites like this are not able to address

Are all of these problems common?

No, these are not commonly encountered issues with MacOS Catalina.

Perhaps the most common issue that may be experienced by users with MacOS Catalina is that some older apps will not work, because of the loss of 32-bit app support. The other issues discussed here are fairly rare.

If you’re on the fence about whether or not to install MacOS Catalina then don’t assume you will experience any of the issues or problems discussed here. This is intended as a troubleshooting guide for problems that a small number of users are encountering, and by no means is representative of the wider MacOS Catalina user base or experience. You can use this guide to get ready and prepare for MacOS Catalina and download MacOS Catalina as soon as you’re ready for the software update. Or you can skip it for the time being, that’s OK too!

    It installed and showed the Island picture, I logged in following initial install, and it stopped on “Setting Up Your Mac” spinning wheel; left it on overnight; next day the screen had locked already; logged in again, brought up spinning wheel. Force restarted computer by holding power til it turned off. Turned power on. Install window showed up and completed. Island picture showed again, and showed some news messages, then disappeared. Logged in. Screen went black for a few minutes and it logged out. Logged in again. Screen black, but showed mouse cursor. Slowly brought up menu items top left, and completed. No further issues.

    Some people with 2018 Mac mini that have bricked completely after installing MacOS Catalina can find a possible solution through this video below. It’s techy and weird but if your Mac is stuck not booting after Catalina it may be why and related.

    Apparently if I understand the video sometimes a 32-bit application is loaded at system start, but since Catalina doesn’t support 32-bit apps the system can’t start and the whole thing breaks. Weird situation. Anyway there’s a way to disable and delete that 32-bit app.

    The solution offered is basically this for terminal, but you must know the 32-bit application that is loading at start and where it is so you can remove it:


    /sbin/mount -uw /

    rm -rf /path/to/

    dsenableroot disable


    If you have this issue you’ll see an error about failing to return kernel address space with an error about something like:


    I don’t know, watch the video below it might help someone with a bricked machine after MacOS Catalina install, the video has a lot of ranting in it so ignore that but maybe some useful information:

    OSX Catalina sucks. Facing so many problems.

  4. Nidia says:

    Installation stucked on a black screen for about 10 hours until I decided to turn it off. When restarted asked my password and never recognized it. It couldn’t be reseted using the Apple ID. I tried to reinstall or repair the HD and it can’t. So I would have to erase the HD because there’s no way to back up to restore. what else can I do?

  5. Ted Striker says:

    Catalina download is unavailable, despite running 10.14.6 on a brand new MacBook Air with plenty of storage. Tried quitting the App Store & rebooted as suggested, but still nothing. Help!

    Issues with Word for Mac

    Selecting any text inside Word for Mac will cause MacOS to freeze for 10 seconds (with the beachball). Then the screen snaps and any text/action done during the freeze will be performed. Selecting again will cause the same.

    Tried selecting using Wireless/Wired mouse, trackpad, shift+arrow, all same results. Sometimes the screen turns Red for few seconds then returns back to normal after the 10 seconds!

    No issues with Excel or Powerpoint for Mac.

    Current setup:
    MacOS Catalina 10.15 (19A602)
    Word for Mac 16.31
    Lots of SSD disk space and 16GB Ram

    Is anyone else experiencing the following:
    When I Shut down my mac, it reboots, showing a black screen telling me to either press any key on my keyboard or wait for an x amount secs. Then it reboots to the login screen, then I can turn my mac of. On the next startup, after login in, I get an error message stating that I turned my Mac of because of a problem, followed by a crash report. However, the problem was turning it of in the first place. has anyone encountered this? And how did you fix this, if you fixed it?

  8. Figaro says:

    Be safe and try Catalina on an APFS volume created with Disk Utility before installing over Mojave. I did, hated it, and just deleted the volume. No sweat, no problems.

  9. Tom says:

    Catalina has decided not to let me print to a Dell printer due to the software being downloaded from an unauthorised site (i.e. The print job is interrupted before being sent to the printer, and only option it offers is to delete the specific driver application, which it then cannot do because the file is (obviously) in use.

    This seems pretty poor, as there is not the usual security override (via the Control Panel) and the print application appears to be 64-bit compatible. Looks like this was not properly tested prior to release

  10. Sam says:

    Mac Mini 2012: No Audio thru HDMI. Workaround PRAM reset after every ca. 3 sleep cycle. Thanks Apple for adding this bull** “feature”. Already resolution was screwed (underscan setting needed to redo after each sleep cycle) after sleep
    cycle in previous MacOS release and now this…

    How can I downgrade to OSX Sierra? Seems Apple sacked their quality department…

  11. Charles Major says:

    Lost many albums, picture comments and photos in the ”Photos” app after downloading Catalina. All my hours of picture organization and chronology are gone. Not to mention photos also.

  12. Ben says:

    I have experienced several oddities: my usb extended apple keyboard on restart after install and after mini updates restart wouldn’t work, I had to use a bluetooth keyboard I had lurking about, then after a little while removing the usb, looking at the system keyboard input tab, looking at system profile usb and repeating that a dozen times, it suddenly decides it will work.

    I’ve also had some files disappear, which threw me, but luckily I had time machine, though I had to recover to a different location and then copy it back to the relevant folder. Recovering to the folder itself didn’t appear to do anything.

    I also had the screen go haywire but restarting it seemed to help, I think it either had something to do with the Adobe Stock Library or the object styles menus in Adobe InDesign CC. Restarting fixed it.

    It seems a little shaky at times but to be fair it is a big re-write. Though some of the bugs have me shaken.

  13. Paul says:

    Loaded Catalina to my iMac , ran great for about five days, then I started having issues with music(wouldn’t close) then screensaver would not stay on my selection, now when I close any browser I have to try “force quit “all hanging applications (music, Firefox, Opera, photos ). Can’t shut down even after 60 seconds countdown.

  14. Jack Ouzzi says:

    Catalina ‘Voice Control’

    This is quite important for me. It is CLAIMED that no voice data is sent to Apple, all being stored locally … OK where is it stored locally, how can I delete this ‘locally stored’ data.

    Anyone have a clue?


  15. TS954 says:

    I found this writeup by Mike a bit shocking. I have never needed to restore a backup when I had plenty of time. The need ALWAYS occurs at the worst possible moment, right? So while his article is brilliant and informative, as usual, I disagree with his conclusion that it is an acceptable trade off. I’m sure that must if the world’s back ups are on spinning hard drives and … well, read the article.

  16. TS954 says:

    I’d suggest everyone spend some time studying the information on CCC’s developer’s website RE: APFS, FileVault, the conversion processes of both, snapshots, Time Machine and how it all affects your backups and clones, especially if you are on a newer T2 equipped Mac. It is very complicated and the potential pitfalls are numerous and perhaps, depending on your setup, more likely than not. I’d start reading with his information about High Sierra and work your way forward. He does a great job of explaining all of it and is a tried and proven resource as is OS X Daily. Many thanks to both!

    Also, I found his article about Catalina and how it destroys the read/write speeds of spinning external hard drives, by forcing their conversion from HFS+ to APFS, to be stunning. I’m sure that most backup hard drives in use today are still the cheaper spinning HDDs. If that is your case, don’t “upgrade” to Catalina. My advice, not his.

  17. Elyssa says:

    I cannot get any of my photo titles to show up. I have clicked and unclicked “View – Metadata – Titles”, I have quit and restarted, I have unchecked Photos from iCloud and reinstalled them. Nothing works.

    The same is true on my laptop, so it’s not specific to one computer. I need to see the titles of my photos. Please help!

  18. Paul Stewart says:

    I upgraded both my Mac to Catalina and my iPhone 8 to 13.1.2. Somehow, a couple of my photos in each of my photo albums have gotten out of order! Also, if I arrange photos on the Mac app, it jumbles the photos on the iPhone, and vice versa. What the heck? Please tell me there is a fix!

  19. David says:

    When it’s finished you’ll have 2 volumes, one named (for example) “MacintoshHD” and then “MacintoshHD – Data”. And neither one seems to be the entire contents of the volume.

    “According to some macOS developer geeks, it is because Apple didn’t yet update the storage tab in “About this Mac” to recognize the new file system layout in macOS Catalina.”

    “Similar to how iOS is configured, macOS is now on a separate partition from user data, which acts as if it is read-only (but in beta 1, it’s merely SIP-protected). In the beta, you’ll see “Macintosh HD” and “Macintosh HD — Data”. Data is a separate volume mounted in /System/Volumes. OS-installed applications live in /System/Applications, but the Finder presents them in /Applications as well. Apple calls the technology “firmlinking”. Beta 2 will be fully read-only by default.”

    If I had wanted 2 damn volumes I would have partitioned it that way! So now I have to 1) either wait until Apple fixes this, or 2) no longer update.

  20. Frans says:

    Installed Catalina but it won’t start. It continues till the end of the progress bar and then it remains there for eternity. No boot!
    I had the same happen with Mojave. Complete the progress bar and stay there for eternity, no boot.
    Luckily I had this experience already, so I had an extra partition running High Sierra to fall back to.
    Ans after reading all these problems you guys encounter here, I even wonder if I SHOULD upgrade.
    And I also wonder if this would happen if Steve was still around.

    Good luck guys. I’m sticking with High Sierra for now.

    • Cornwhallus says:

      No, there is little reason to install MacOS Catalina.

      There’s a saying in Texas, “If it ain’t broke, don’t fix it”

    • The Skeptic says:

      “I also wonder if this would happen if Steve was still around.”

      OS X 10.5 and OS X 10.7 were both released under Steve, and were widely reported to have lots of issues.

      A clean install (after a backup) may well do the trick for you.

  21. Bill Geraci says:

    Greetings! Here’s the only thing I’ve noticed (so far) where Catalina seems to hate me. ;-) In Photos (version 5.0 (101.15.190)) 2/3rds of the time I try and write a description into the Info Description field it will delete the description and replace whatever I’ve typed with “Looking for descriptions…” which I can then select and type and it’ll usually delete that again. Weird.
    MacBook Pro (15-inch, 2017), 10.15 (19A583), 2.9 GHz Quad-Core Intel Core i7, 16/1000, with German keyboard (in case that might matter).

  22. Anon says:

    My clock has been lagging several seconds behind since I downloaded Catalina, and it’s falling more and more behind each time I check.

    I have the date and time set automatically (Apple Americas/U.S. (, as well as the time zone.

  23. Mikee says:

    Here’s my list; install froze 2 days; day 3 all username/passwords deleted; day 4all desktop content/Documents/ apps, everything/ deleted off desktop; keeps asking for ‘old’ mac password; unstable as can be, everything keeps crashing; still do not know where all my data went; all functions suer slow, I see the win wheel more than I se anything else; ‘add password’ function doesn’t work, that started day 6; password preferences logs out after about 20 seconds; anti-virus fighting with some other function, works but never ending updating now,,,, and thats just as of day 8, Apple is baffled (surprised?). I’m going to drive 2 hours this week to take this paperweight into the Apple Store, DO NOT install this software until they have the bugs out (Mac mini, 2012/ 1TB drive, 1600 RAM) Summary, Dont Install this until they get the bugs out!!!!!!

  24. shiyu xu says:

    After I installed OSX Catalina, my iMovie is not able to access Photos. Does anybody have the same problem? Anybody knows how to fix it? Many of my other applications were broken, too. I am really frustrated. Any help will be appreciated.

  25. Ken Campbell says:

    after upgrading to Catalina my imovie drop down menus dont work – screen just turns purple with wierd geometric design – same with some other apps too – can’t even shut down via top left hand corner apple button – can’t get the drop down menu here either. I’ve tried deleting imovie and installing it again but that doesnt solve the problem – yesterday I could manage the preparation of my movies – now with catalina I can’t do anything – what a mess

    • Tina Miller says:

      Me too!!! I am so frustrated. Someone said that maybe the installation of Catalina wasn’t completed correctly due to an internet issue but I don’t know how to reinstall it or if that would even fix the problem. I have an iMac late 2013 model. Let me know if you get this resolved!

  26. Paul Johnson says:

    This may be helpful for someone who has been unable to connect to a network drive using SMB. I found a very simple solution.

    I have a local network that includes a Mac mini server with an attached USB drive, and after upgrading to MacOS Catalina I was unable to mount the drive from any computer on the network.

    I found many posts on various forums that reported the problem but none of the suggested “solutions” solved the problem for me. (And on one forum I was even chastised for reporting the ineffectiveness of two suggested solutions.)

    Here’s how I solved the problem:

    On the Mac mini server I displayed the Info window for the attached USB drive and selected “Shared folder”.

    Now I’m able to access the drive from my other computers in the network.

  27. Matteo says:

    Actually having the “Mac Running MacOS Catalina Randomly Crashes & Restarts” issue. Hope it will be solved with some update.

    Also, Music keeps on having an activity going on “load illustration”, that I don’t understand. I have noted that a new folder “Music” has been created, similar to the old “iTunes”, but iTunes keeps on existing with the library files. Hope they can cohexist.

  28. Roger Bell says:

    the download of “Catalina” took 3 days and the mail function didn’t work for another day. Currently having problems accessing my music files – previously on “iTunes”

    I am getting a message – “accessing music files may take a few minutes” Fair enough I thought – that was 36 hours ago…I have 3 Apple computers and I am not sure given this experience that I will move the other two over to “Catalina”

    So let me see – I couldn’t use my MacBook Pro for three days – I had tow other machinist use for my business so in the grand scheme of things it is not a huge problem for me – but what about people or businesses relying on “one machine?” In effect they are out of action for several days….

  29. H Hakim says:

    My Acer KG241Q monitor could not detect signal from my Mac Mini 2018 using HDMI to HDMI, or USBC to HDMI or USBC to DP ports after upgrading to MacOS Catalina a few days back. It worked fine only once, but when rebooted, it went blank all the way, even after forced shutdown a number of times. It was working superfine under MacOS Mojave. I don’t have access to monitors/displays anymore, and hence can’t even troubleshoot.

  30. John says:

    Catalina S U C K S.
    I’ve lost my 3 favorite programs, plus numerous others, due to the elimination of 32bit support. I mean how much would have hurt to continue to support it? Ridiculous.

    So, I figured I’d open TIME MACHINE, and go back to the day before CRAPOLINA, and use MOJAVE again, (which incidentally I loved.) Well, CRAPOLINA completely wiped out my Time Machine backups, prior to the Crapolina installation. I’m really beside myself angry that Apple would put put out such a huge piece a S H * T as this.

    Totally unacceptable.

  31. tom mcgarrity says:

    since microsoft office isn’t working, now, it tells me to go to app store to get 365. BUT, not accepting my Apple ID password. when i try to change password, it tells me to use my unlocking mac password … which it doesn’t accept.

    its a circular problem. help!!

  32. Dom Williams says:

    Apple TV App in my 2015 MBP now reports that my screen isn’t HDCP compliant can’t see the video to any purchased movies or tv although I still have sound. I feel a roll back coming on. 😡

  33. Whit says:

    Preview does not allow searching anymore. it will populate on the sidebar with the pages the phrases I am searching are found on, however, it wont actually show them on the page or allow me to find the “next” instance of it.

    Also continually getting warnings to accept user terms and agreement, and I have…. about 50 times. still shows up as needing to do it. Literally every time the screen wakes up.

  34. Andrew Griffiths says:

    Tried the normal update – got an error message that the update could not be completed because there was an error removing the old (Mojave) operating system. Tried it several times with no success. Created a bootable disk on a flash drive and tried to install from that but got the same message. Decided the only solution was too format the main drive (startup disk) – deep breath – knowing I had a Time Machine backup.

    That worked – Catalina then installed OK and I restored from the Time Machine back–up. As far as I can see everything is working (minor issue with Mail telling me there was not enough room in my home folder when I had over 100Gb free!). That seems to have resolved now.

    Major issue for me is that I cannot run Final Cur Pro X. The program quits every time I try to load it. I’m hing the 10.15.1 update will sort that!

  35. Jane Smith says:

    Since I updated to Mac OS Catalina, I have had some issues.
    When I type on the keyboard it repeats 3 or 4 characters (which is a drag when put passwords because it always goes wrong. Example: When I try to write Catalina appears “catlinaina” or “catactalina” or when I try to type Quando appears “Quanuado” or when I try to type more appears “More ore” or when I type the word try appears “try tr”.
    I called apple support and they tried to fix it through the “smc” and “pram”. Not only was it not solved, but it added one more problem: The Delete key no longer quickly erases a few words when I press and hold but it does character by character (about one per second) and so do the arrows keys.

    The battery is also going really fast but I’ve seen a lot of people complain about it.

    Some help please?

  36. Lee says:

    I installed it on a test machine, saw it was rubbish and wiped it

  37. João costa says:

    My Catalina Installation stuck at ”IOHDIXcontroller: note: administrator is creating non-ejectable disk”
    I know many users have waited hours for installation to complete… mine is there for 4/5 hours.
    Any ideas please.

  38. Mr. H. says:

    All went well until I tried to remove some of the desktop pictures. Minor point, I know but…
    I get a message that says the macOS needs these.
    Any ideas?

  39. Renie says:

    Since the upgrade the screen resolution is off and I can only see half my screen so I can answer the questions on the other half… anybody got any insights?

  40. William says:

    Catalina inhibits and causes backups to an external hard drive to take an extreme amount of time and fail. With High Sierra and Mohave, it took approximately 10 minutes to backup my iMac [including encryption]. With Catalina, time machine indicated 10 hours [later reduced to 6 hours] but, the system kept stalling at 4 hours and would not complete the backup.

    I gave up and just did a backup of critical files to a memory stick. I have older backups and am considering undertaking the task of converting my system back to Mohave as this system is slow, cumbersome and not worth the trouble.

  41. Mgm says:

    Well,,,, So far, it froze during installation, 2 days to get it unstuck,,,, next day, my entire username passwords files erased themselves,,,,,today, the desktop completely wiped itself off of any icons or data, except for my background photo,,, lovely upgrade Catalina is,,,,,not!

  42. Art Jacks says:

    I upgraded and the installation went OK on a late 2016 MBP, my issue is with Adobe Bridge which will not show the contents of my Desktop, Download or Document folders, in the file structure on the left of Bridge these folders have a downward pointing arrow on them and if the folder is clicked in the normal way a message is shown saying no items to display but they are there when using Finder. I contacted Adobe support and they said they are aware of the issues with Catalina and they are working on a fix.

  43. Lucia says:

    Since using Catalina, I cannot use Draftkings Sportsbook on my MacBook. I informed Draftkings but they did not know how to resolve, just to make sure my intranet cable (what??, never mind, thanks)
    Anyone else encounter this or at least have a reason why it does not “locate me” properly? Maps and other apps know where I am so not sure the issue.

    • Brandon says:

      I had the same issue with draftkings sportsbook site. I ended up going back to the previous iOS until the bugs are all worked out. Are you still having the issues? I saw their was a iOS update but didnt want to try it yet.

  44. Clinton says:

    We currently have a 66% roll back rate on this botched up install.

    Not only have we seen all of the above issues but drive I/O access issues after. Many SSD drives don’t report well with encryption. So lots of boot faults and hangs under APFS.

  45. Mike O’Connor says:

    My 2015 MacBook Air has been rendered useless after attempting to install Catalina. I was on my iPhone with Customer Support for almost 3 hours and the situation only became worse. Now, I have no working MacBook Air and Apple will not rectify it after their damned OS decimated my hard drive. Do not, under any circumstances, install Catalina.

  46. jaybee says:

    Since upgrading to catalina, I’m not getting icon previews for music files – in particular .aiff and .m4a apple losseless. These files display on desktop and in finder with blank icons. (some mp3 icons do appear though.)

    is this a bug or am I missing something?

    Any suggestions would be greatly appreciated

  48. Richard says:

    Since installing Catalina, apple music does not work properly. If I play a recommended album, the playback stops after each track and therefore I have to manually select play for each track.

    Also sometimes apple’s playlists play ok, others, times only a few of the tracks are played before playback stops.

    I didn’t have any of those problems with the previous version of the operating system using the iTunes app.

  49. threbus says:

    Two-user MBP; secondary administrator. Catalina kept asking for my Apple ID repeatedly—entered it, asked for my log in pw, entered it and it recycled; waited a day; logged out, restarted, had it asked for again, entered it and log in pw, but this time I waited a little longer; after 5-10 seconds, I got a request for a passcode for one of my other devices. After that, the prompts and the warning triangle went away. Done!

  50. Simon says:

    Please How do you now reset the network settings ie delete network prefs in Catalina, as I can’t locate system configuration folder. It is not viewable or searchable so I can’t access network prefs to delete or move out of the folder.


    • Daniel Wells says:

      You can’t maunually edit system folders at all…The system files are on a disk that is read-only now. You can get to System Preferences for the APPLE menu though.

  51. Great Article. After installing Catolina on IMac I have three yellow triangles

    Confirm mac password
    Update Apple ID settings
    Update Apple ID settings (yes 2 the same)

    After trying to add password message reads can’t connect to server or my password is wrong when I know it’s correct.

    Any ideas on a remedy

    How many others have similier issues?

    Cheers Simon

    • Opinionated says:

      You should call (800) MY–APPLE (800–692–7753) which is Apple’s official tech support phone line and make them walk you through the resolution to your problem.

      Everyone else is just guessing, or trying things on their own, hoping this or that will work, and maybe it does. But this is Apple’s mess and we are just working through it as fellow users.

      Apple created the mess with Catalina, broke a lot of stuff, so call them and let’s hear their explanation on how to fix it. I would like to know what they say, though their call center employees probably don’t know yet either.

      I have seen other people say the Apple ID password is being rejected despite being accurate, that is a common issue and obviously a problem with Mac Catalina.

      • Daniel Wells says:

        APPLE won’t give you free tech support via the telephone UNLESS you still have time left in your tech support window…the first 90 days.

    • Rider Boy says:

      I had the same problem with System Preference Apple ID function not recognizing my Apple iCloud ID. My issue was resolved by deleting my NordVPN program which I was using to watch blacked out college sports in my area. Even tho it was turned off or so I thought, it was interfering with my internet connection to the Apple ID Server. Once I deleted the VPN and restarted my Mac, the issue resolved itself on startup like magic!

  52. James says:

    Upgraded to Catalina now the Extensions off the Edit mode of Photos does not allow the changes to be saved. Get error message that states: Unable to Save Changes for “Luminar 3”. Ab error occurred while saving. Please try again later.

    • René says:

      Same problem here, I hope either Apple or Luminar can fix this, as it makes the otherwise brilliant Luminar plugin useless.

  53. Darren McCoy says:

    Everything went smoothly for me. Does anyone else have a minor problem in finder? When I open my download folder the last download is always above the interface. I always have to scroll up to see the last download.

  54. Bobby Papoutsis says:

    My MacBook Pro, which is compatible with macOS Catalina, won’t even upgrade to 10.5 because the download always seems to fail once I’ve gotten past a certain threshold. In my case, it’s after I pass 5 gigabytes out of the 8 gigabytes you need to download. From there, then estimated time remaining jumps to 12 hours to 3 days. Then it just fails and I have to start from scratch. This has been a persistent issue for the past two days. Is it because of congested network traffic on the part of Apple since so many people are downloading this? Is it my internet connection? I don’t think it is because I can stream HD without buffering issues. I have it downloading again and hope that it won’t fail with another error.

  55. Catherine says:

    Since I updated my Mac with Os Catalina, the screen is stuck with Screen Time. I can’t access any application, nothing!
    Anyone could help?

  56. Is there a list of applications, like 32 bit ones, people have encountered ?
    a list of those not upgradable?

    This would be hugely helpful if a user requires an application that is unavailable!

  57. Richard says:

    Noticed my disk space percentage was radically reduced… decimated, actually. Went from 81% to 8%. There are 32GB of space eaten up by “Other” with no idea what that “Other” is. Any ideas?

  58. Daniel says:

    Sit for days if it takes that long. Are you right out of your mind? Wait for days for an install? Not very likely.

  59. Daniel says:

    Lost the entire Time Machine backup history (about 3 years of backups) after upgrading to Catalina. Only the backups made with Catalina are shown when opening Time Machine.

    • Mike says:

      I have the sam issue on 3 different machines 2 iMac’s and a Macbook Air. Spent almost 2 hours with Mac support, tried to tell me I needed to format my time capsule to APFS, which can’t be done

    • Scott Hayward says:

      Ditto, I have the same issue. I cannot access pre-upgrade backups, even though time machine says they’re there (1.3/2.0 TB of the disk are in use).

  60. SalParadise says:

    Music and TV apps will update album and DVD covers over time. Just leave the apps open. I hope they’re not being grabbed off the net. All my albums, TV shows and movies had art already attached to file in iTunes.

    Also the remote app on your iPhone or iPad doesn’t work with Music. Which sucks. Hopefully Apple will update or fix the app.

  61. Robert Mansfield says:

    I have upgraded to Catalina but iPhoto has disapeared along with all my photos. Photos is ticked ini cloud but nothing has come back?

  62. Bernt Ringström says:

    Can’t use playlists in Music.
    My personal equalizer preset function drops after each song but still indicates ‘on’ and must be reactivated.
    Most annoying.
    I must control myself and not update first day…

  63. chbrunne says:

    No, you’re not missing anything. The view you are looking for, doesn’t exist anymore :-(
    And the album artwork problem is a general one:

    Catalina isn’t a great update for music, because Music is a dork… ;-)

  64. Todd says:

    Since upgrading to Catlina, Word crashes immediately upon opening. I know this is not isolated to me, others are reporting it too. I spent 2 hours on a chat “hold” with Microsoft with no resolution. That was after 2 help sessions with Apple, thinking it was a Catalina issue.

    • Scott says:

      I’m able to use Word, but I can’t save a document in Word format. When I try to save a document, the document title bar changes from Document1 to the file name I’ve chosen, but after a few seconds, it changes back to Document1. I was able to “print” it as a PDF file, so I have a copy of it, but if I want to open the document again, I’m hosed.

  65. Fulvio says:

    I just updated to OSX Catalina and I lost (or not yet found) the way to show the Album Artwork (on the left side) when I select “Songs”. This is very annoying as the list with the Album cover was more “view” friendly than the actual “text” list. Have I missing something? Anyone else?

    Thanks for shed some light.
    Regards, Fulvio, Switzerland
