Fix Frozen App Store Updates and High softwareupdated CPU in OS X

Jul 1, 2015 - 115 Comments

Stuck App Store frozen Updates tab

Some users who are trying to install OS X Yosemite 10.10.4 or iTunes 12.2 have discovered the Mac App Store will freeze, with an endless spinning wait cursor and the updates never showing up. Investigating further reveals that a process called ‘softwareupdated’ simultaneously goes haywire and consumes 99% CPU for an indeterminate amount of time if left unattended. If you encounter either of these issues when trying to install the aforementioned updates, there are several possible resolutions to this, but you’ll have to temporarily circumvent the App Store in either case.

After encountering this issue myself while attempting to update one Mac, I was able to resolve it by manually installing iTunes from the command line software update mechanism, which avoids the App Store.

First, if softwareupdate is consuming significant CPU, you can kill the process with the following Terminal command:

killall softwareupdated

Next, you can install iTunes 12.2 update manually with the following command string:

softwareupdate -i iTunesXPatch-12.2

Once iTunes 12.2 installs and is no longer available as an update, everything else worked fine in the App Store as usual in my case.

Install an update through Terminal of OS X

For some users, the problem has persisted with the actual OS X 10.10.4 update as well.

For installing OS X 10.10.4, you can either attempt to update from the command line, or download and use the Combo Updater. Either way you’ll want to back up the Mac beforehand, like you would with any other system update.

The command to initiate the OS X 10.10.4 installation from the Terminal is as follows:

softwareupdate -i OSXUpd10.10.4-10.10.4

A restart is required to complete the installation.

Getting software updates from the command line results in the same versions as downloading from the Mac App Store, it just avoids the application itself which is hanging for whatever reason.

Most users should not encounter this problem, but if you do, let us know in the comments if these solutions work for you.

    I have the same problem. I’m attempting app updates on this just-out-of-the-box “new” MBP mid-2014 running Yosemite 10.10.2. Curiously, Garage Band updated successfully. But Numbers, Pages, Keynote, iPhoto, and iMoving all get stuck spinning after clicking update. Haven’t tried the suggested solutions yet. Being new to Mac, I did not want to update all till I get a chance to look around Yosemite before updating to Captain. Kinda disappointed. I’m used to this kind of sloppiness on Windows – didn’t expect it on Mac.

    • RickR says:

      It mostly worked after doing the terminal command: softwareupdate -i -r

      That upgraded the OS to Yosemite 10.10.5

      Afterwards, I could use the App Store interface to “Update” the other apps – with a couple of remaining challenges:

      1) After updating one app, the button would change to “Updated” for all the apps. I had to exit App Store and reenter it to reset the buttons to allow further updates.
      2) App Store says iPhoto needs update, but then refuses to do so saying something about using the wrong AppleID (I only have one). But somewhere along the way, Photos was installed which I now understand is a replacement for iPhoto. Fine. But curiously, App Store still reports an available update for iPhoto. The terminal command:
      software update -l
      says no updates are available. o_O

  3. Chris says:

    Is there a simple answer yet out of all this? It is very time-consuming, especially using the Mac for work, to reinstall the whole operating system (and many other rather time-consuming bugs I have experienced since Capitain. I’ve three Mac devices and about to buy another, but it is a bit depressing that core functions can’t just work as they should.

  4. Jan says:

    Update of OS X El Capitan Update-10.11.1 stalled during download and “calculating” message. Now with this command line procedure I could do the update. Hope this update will fix also future update issues !

  5. Matt says:

    After the update I cannot get any program to work properly, Not even able to click on anything due to constant spinning deathball, anyone else having this issue?

  6. Betatron says:

    I had trouble with Software Update stalling on this week’s iTunes update. Force Quitting Software Update solved the problem (force quitting, not just closing the app normally).

  7. Orestes says:


    Using the command line to install, I finally solved the problem.

    Using a Mac Book Pro (late-2009) with Yosemite 10.10.3

    Thank you!

    Using the command line to install, I finally solved the problem.

    Thank you!

  9. Gary Roquemore says:

    two MacBooks here with the older one updated no problem from App store. 9 month old macbook air though had the App store searching for update issue. So found this site from search and started OS 10.4 update from the command line code above (It was the big file so did not try all the updates). Got up this morning and it is 15 hours later and it is still loading code into the console. So I’m looking back in the terminal window and it says the update tool was started, then a line about error service connection interrupted. Then a line could not communicate with helper application. And started update without it I believe. I’m taking this is the reason it is so slow. I don’t need the Air specifically and can just let it load slowly? Our should I kill it (How do I do that?). Any thoughts and help would be appreciated.

  10. Javier says:

    Thank you very much! It worked!

    Macbook Pro 15, mid 2009, Yosemite

  11. TheLostDutchman says:

    Didn’t need the iTunes, but the 10.10.4 upgrade from 10.10.3 never appeared in the App Store updates, but amually applying it resolved my issue.

  12. Chuck says:

    Thank you sooooo much! This solution fixed my issue. 😀

  13. Mick says:

    I’ve all the same problems as everybody else. When I tried the terminal method it immediately went to “Finding available software” and it’s been there for over 20 minutes already. Not sure if it’s hung or if it’s actually downloading anything and just taking a while. How long has it stayed at that spot for people who had successfully updated?

    • Mick says:

      Finally got it working. I did have to abort the terminal method. I deleted all the stuff in /Library/Updates and then used the terminal method again and it all worked.
      Thanks (but not to Apple).

  14. Wil says:

    Thank you. This fixed my issue.

  15. Julio says:

    Thank you!!!

  16. Dan says:

    This method worked perfectly! thanks

  17. Jerry says:

    I don’t need an update to my software. Apple, when you get the update to work like updates are suppose to work, let me know. I’ll wait. No stink, no stir.

    I’m reminded of a saying, ” I’ll be on the leading edge, not the bleeding edge.”

  18. Kookie says:

    Manual iTunes update worked perfectly for MBP 13″ Retina, late 2012.

    By the way, how does one find out the command line for a specific update?

  19. Sam says:

    I’m experiencing the problem you listed exactly. When I tried to update iTunes 12.2 the updates tab in the App store freezes on me.

    I’m not a computer science guy at all, but I tried to follow your steps in the terminal. I put in the iTunes patch and it says “Finding Available Software” but nothing comes up after that. Am I missing something? Thanks for your help!

    • Sam says:

      I did software update -l and it listed the updates, including the iTunes patch. Then I did software update -i iTunesXPatch-12.2 and it was “Finding available software” and then it says “Downloaded iTunes.” But when I open iTunes it definitely isn’t downloaded, and still wants me to update.

      • Sam says:

        Nevermind, it worked after all. I just went back into the app store and it said it was downloaded. Thanks so much for your help. I love this Macbook. This is the first problem like this I’ve had and I was scared. But your fix helped a lot! (And taught me a bit more about code!)

  20. Anders says:

    Excellent tip! However neither “killall software updated” nor “sudo killall software updated” worked (still using 100%). Rebooted and then ran “softwareupdate -i iTunesXPatch-12.2”. iTunes was installed and then the normal update procedures via App Store worked flawlessly.

  21. tedd says:

    Hey! This solved the problem! Thanks a lot for the solution!

  22. MyHumbleRant says:

    It seems that OS X 10.10.4 was my issue. Thanks for the help!

  23. mark says:

    It worked

  24. Niek says:

    Thanks!! I was extremely p*ssed off, already restarted AppStore and Mac for about 10 times, and my MBP 13″ kept going hot and didn’t do any updates. Tried it via Terminal, no problems at all!

    Thanks so much for this post!

  25. Thomas Meyer says:

    Had the same problem with MacBook Air (11-inch, Mid 2012), your fix worked perfectly, App Store app is back to normal, thanks a lot!

  26. I am using a brand new MacBook Pro (2 months old) and have found myself in a never ending loop of downloading the update, seeing the restart button, then going back to being prompted to download the update again.
    Two hours and counting of this now.
    I think I might be going mad.

  27. Hannah Pabinguit says:

    My problem was that even after it said it finished installing it wouldn’t go away from the list of available updates and even after trying to update through the command line. The only updates I still have left are the OSX and the iTunes. After downloading the iTunes one alone, it still wouldn’t go away. If I tried to just download the OSX update, it would ask me to restart but upon clicking, the restart pop-up on the right (the one that countdowns from a minute), it would say something like “Your available updates have been changed/updated. Click for details.” and it would go on loop. If I just plain restarted, nothing gets installed or updated at all. Is this update even necessary? What a pain

  28. Kenneth Hansen says:

    Thank you Simon Bolton för your solution. That worked fine for me. You Saved My Day :)

  29. Kevin says:

    When I go into my App Store updates, I see updates for Garageband and iMovie, but not OS 10.10.4. In addition, whenever I get the update notification for iTunes 12.2 and click ‘Download iTunes,’ it takes me to the App Store update page, but then says ‘Can’t connect to Apple update server’ even though I am downloading the iMovie and Garageband updates. What can I do here to get the App Store working correctly?

  30. John R says:

    Folks, I immediately had issues when I updated to iTunes12.2. I could not QUIT iTunes. I always had to Force Quit. Both my iPhone4 and iPad Air became unrecognized by iTunes12.2. Some of my iMac stored movies were missing and moved around. So I rebooted and reinstalled OSX10.10.4 which included iTunes12.2. Rebooted repaired disk and repaired permissions. iTunes12.2 has same issues.

    Called Apple Support. After about a half hour, we determined that my iPhone4 needed to be rebooted. Fixed all iTunes12.2 issues.

  31. MacRules says:

    Your solution worked for me.

    I had the “checking for updates” circling arrow after initiating the iTunes 12.2 update.

  32. Miguel says:

    Thanks! You’re the man!

  33. kalani says:

    I had same exact issue. Downloading the combo manually from website resolved the problem. Pretty spectacular foul-up judging by the large numbers of people affected.

  34. mehere says:

    Worked exactly as advertised. After installing iTunes with the command line utility the App Store worked again and I was able to install all other updates. Thanks!

  35. Justabrake says:

    Had to format my hardrive after the update, it never took only a blank screen on my macbook pro 17″2011 late edition

  36. tokai says:

    The “softwareupdated” trashed its cache data. Probably it got confused by the App Store problems. For some reason it can not recover from this situation (see strange error messages in the “/var/log/install.log” file.

    To bring it back normally one can delete the broken cache files and information. It’s located in a rather hidden folder in
    “/var/folders/zz”. Do a “ls -l” and locate the sub folder owned by “_softwareupdate” and delete this on. After a reboot everything should work again (until the next time it trashes its data when the App Store is down ;) ).

    For those less “techy” persons a bit more crude variant:
    * Activte the Finder in the Dock
    * Choose “Go > Go to Folder…” from the menu
    * Type: “/var/folders” into the dialog and click “Go”
    * Move the whole folder called “zz” to the Trashcan (you need to type your password) (1)
    * Reboot.

    1) Moving the whole “zz” folder is a bit more crude, but does no harm. It only contains various temporary data by various system processes and can be safely deleted.

    Can’t update to Xcode 6.4 here. The wheel just keep spinning forever and command line update can’t use with Xcode update

  38. Sven says:

    Is there an issue with not updating 10.10.4 until Apple fixes the software update (and, from the sounds of it, the software itself) in, presumably, the next couple of weeks?

  39. Anthony says:

    I had to restart my Mac to get it to work from the terminal because the App Store was doing way too much without the processes showing, but it worked fine other than that. I can finally update Xcode that came out as well.

  40. Utsav Raychaudhuri says:

    Went ahead with the update. Completed the update and then when my Mac went to restart my Mac shut down but never started back again. Tried every possible thing from resetting the Smc/nvram but nothing. Till now. Don’t know what to do.

    • Gondor says:

      I would restore from a backup and avoid OS X 10.10.4 it’s proving to be more problematic than it’s worth. How Apple continuously releases these mucked up OS X builds amazes me. This thing went through a public beta, it’s supposed to fix bugs not create new ones!

  41. Oscar says:

    I have the same issue with my 2015 MBP. App Store updates we a no go for 10.10.4, iTunes, and Garageband. My 2011 MBP didn’t have any problems with App Store updates.
    Doing updates by the command line, I did notice that none of the updates show up as installed through the App Store.

  42. UglyStuff says:

    Sorry, I meant **atMonitor**.

    ActMonitor is a monitoring tool for iOS… My bad…

  43. UglyStuff says:

    You can also use ActMonitor to renice the offending process(es).

    Once you’ve set the right priority and clicked on “Set and remember”, your process won’t gobble up so many CPU cycles.

  44. hajrudin says:

    I tried the command lines in Terminal but it’s stuck finding updates on there too.

  45. Schwach says:

    I updated with terminal -i -a but app store stills showng 2 updates:
    – Yosemite recovery update
    – Xcode update
    i can install it again and after installation they are still there..

    And itunes 12.2 says “you need itunes 12.2 to use Music”

  46. Ixmntr says:

    It seems that mostly MBP’s seem to be affected. I also had this issue and downloaded the combo update and that ended up working.

  47. Wharf Xanadu says:

    Ran into this on a MacBook Pro. Worked perfect as described. Thanks.

  48. Mellie says:

    Booting in Safe Mode allowed me to install all software updates after the store froze up with a grey screen.

    After rebooting as usual, the app store worked as expected.

  49. MikeK says:

    (Clarifying slightly — I quit the App Store, force-quit the daemon, then re-launched App Store. After multiple iterations of this, I would finally get a successful update.)

  50. MikeK says:

    I had this problem on two Macs. Repeatedly force-quitting softwareupdated eventually allowed the update to complete.

  51. MoreBucksThanBrains says:

    I just buy a new Mac Pro every time an update comes out. Much easier to have the brainiacs set it all up for me and deliver it, then I throw away my old system.

    Try it, it might save you a lot of hair.

  52. Jupiter Antunes says:

    I also faced the problem… For several times I forced quit the installer, booted the MBP and started again…
    I really don’t know why, but as a magic I received the message that The computer will be restarting to complete… No progress information, no other messages…. and then… after the restart… 10.10.4 was there…
    That is it!

  53. Brooklyn Geek says:

    Sounds like Apple has serious quality control problems with their software.

  54. Hija del Rey de Israel says:

    Thank you.
    God bless you.
    The day you face God, He judges you by His law (no lying, no hating, no using His name in vain, no lusting in your heart, etc); you’d be guilty. The sentence: a timeless lake of fire made for Satan and his angels. If you want eternal life accept the legal transaction Jesus Christ did for you on the cross over 2,000 yrs ago (deny yourself, carry your cross, follow Him) so your case can be legally dismissed and you’ll be granted eternal life with Him (no more sorrow, no more death, no more crying). Eternity is timeless; I wouldn’t want you to wake up in hell (if you wouldn’t sell your eyes bc you love them, how much more should you care about your eternal soul). 151,600 die each day. GBY!

      So uh, how about those Macs eh? Well, uh, how’d that OS X update work out for you then?

  55. julian says:

    thanks! your solution works for me, but after rebooting my mac.

  56. Amol Deshmukh says:

    I tried the given solution but it did not worked. The terminal was did not showed anyting after Finding available software. I think the software update was downloaded but did not install as many times the popup for restart was coming on my screen but when I clicked restart it did not did so.

  57. Andy says:

    Thanks! I have this problem and yours solutions help me!
    MacBook Pro mid 2012 10.10.3

  58. Blair says:

    I saw the looking for updates hang on the App Store, so I downloaded the 10.10.4 update from the Apple Support downloads page.
    Running the update produced the softwareupdated problem.
    Couple of things I noticed using Activity Monitor:
    – Cpu usage dropped if you minimised the Installer window
    – softwareupdated was showing 40GB of memory used, and 65K ports!
    Something obviously very wrong! Memory pressure slowed the system to a crawl
    Anyway, I shutdown everything and restarted the system, and the install ran normally. App Store worked with no problems after the update.

    • Roxy says:

      I noticed the same thing with softwareupdated taking up 30GB of RAM, LOL. Something very broken. Apple, come on, this is our productive OS X! iOS is for kids, OS X is for adults, lets get this thing working.

  59. Hal B. Rager says:

    I was having this problem on my wife’s MacBook Pro from mid-2012 running 10.10.3. I ran ‘sudo softwareupdate -i iTunesXPatch-12.2’ after doing ‘sudo kill -9 220’ [process id for softwareupdated]. [Old unix habits] After this, the App Store worked just fine. Thank you.

  60. Richard Moore says:

    RE Mail not working with gmail, I had to re-enable the “automatically update settings” in imap and smtp preferences — once that was done, Mail started working immediately.

  61. Michael says:

    I found that going into Safe mode and then doing update resolved the problem. Only had problem on 1 of 3 Macs.

  62. Edward Stern says:

    I had the same problem on a 2011 MacBook air running 10.10.3 Software update would not refresh and the fans were on constantly. I used activity monitor to check CPU usage and software update was not even running. I tried the terminal procedures and none of them worked. So i went directly to Apple’s website and downloaded the basic 10.10.4 update since i was running 10.10.3 the updated installed fine but fans still ran at high speed, then I went to software updates and ran the new iTunes update. Installed and ran fine. fans still on hight I went to activity monitor and saw something to do with software updates using 28% of the cpu. Killed the process and fans finally stopped running. Not sure why that was still running after both updates were applied.

  63. Josh says:

    Anytime this happens I just run CCleaner to remove temp files and misc. caches followed by repair disk permissions & restart.

    • Eiman says:

      I did the same (with another cleaning software) and did a repair disc permissions. It resolved the issue.

  64. Mike says:

    Had problem with one of four machines.
    softwareupdate -i -a solved the problem.

  65. RF Lampe says:

    Had the problem and did a safe boot which allowed me to access the app store. All seems good now.

  66. raphaellz says:

    I had the same problem here, thought was because my isp or some firewall on my macbook.
    The solution for me was logging off from Mac App store, restart and reset pram, download both itunes and osx10.10.4 update from apples website.
    it worked fine after.
    But i still have a problem with other updates.
    Pro Video Formats Ver: 2.0.1 keeps showing from time to time as a needed update, and I have already dowloaded it from apples website too. Anyone with a solution?

  67. Fred Flinstone says:

    Thanks a bunch. showupdates didn’t show the Xcode 6.4 update, but once all else was updated from the terminal, AppStore was able to update that.

    thanks again

  68. Simon Bolton says:

    I had same problem today… my solution was to delete all in the Mac HD/Library/Updates folder, reboot and rerun App Store Update and all was fine :-)

  69. Rob Durnford says:

    I experienced similar problems with the App store, I was running the 10.10.4 beta and still had these issues I Force Quit The App store and App web. Couldn’t get a resolution of the issue until I did a restart them App Store worked normally for most application OS downloads on a Update All selection, however Xcode did not install and insisted on my password to download update. Must be new for Xcode downloads

  70. Mike says:

    I had the same problems, process softwareupdated taking max CPU, running beachball when trying to update using App Store.

    Solution for me (MacBookAir 13″ mid 2012) was to kill that f#cking proces and restart App Store to get the Yosemite 10.10.4 update. Once downloaded and installed Software Update kept running as advertised, no problem getting iTunes 12.2 or any other update.

  71. Strange?

    When i paste:

    softwareupdate -i iTunesXPatch-12.2

    Terminal answers:

    Finding available software
    iTunesXPatch-12.2: No such update
    No updates are available.

    Any idea why?

    • t says:

      You probably already have the update installed

      softwareupdate –list will let you see what is available

      • Nope.. I didn’t have it installed..

        It’s funny.. I have never been able to get a new version of iTunes through the Mac app store on my Macbook Air.. I always have to get it manually.

    • Rich says:

      Mine returned the same message saying no update to iTunes was available, but I know I had not updated it. I did the OS update and it found the update and restarted. After the re-start, the iTunes update now shows in the App store and it’s no longer frozen, so I updated it from there and it worked fine…

  72. Firdaus says:

    Same goes to me. Download combo manually from website.

  73. smh says:

    I used the following command to install all updates:
    softwareupdate -i -a

    • Don McFarland says:

      This worked for me, too.

    • Rick says:

      I didn’t work here. It says:
      “Finding available software” and nothing else.
      Cant update the OS or the iTunes. Both gets me stuck.

      • Matt P says:

        I had to force quit and then restart and then try it again (with nothing else running) but it did do it eventually…

        • Rick says:

          I managed to do it by manually downloading it from Apple’s website and installing it. I had to reboot to be able to install it (don’t know why) and, after that, the update mark was still on on the Mac Store icon. I opened it and let it spin for quite sometime until, eventually, it understood that i’ve already updated.
          Now everything is fine.
          …I hope!

      • Claude says:

        Same for me, I’m stuck waiting for available software to show.

        I had updated to 10.10.3 on month ago when I tried to update Xcode to 6.4 ; it’s a mess since.

        • upaj says:

          Open Terminal (found in /Applications/Utilities/) and type:

          softwareupdate -i -a

          This will initiate a manual update of everything including Xcode

    • Matt P says:

      Worked for me too, THANKS smh. MacBook Pro was almost stationery this morning.

      [FOR ANYONE READING THIS NOT V TECHIE (like me) you just need to hit Command-Space to open Spotlight Search and then type ‘Terminal’ and hit return. Then copy and paste the line above into it and hit return. Mine took 20-30 minutes to search, download and install – even with v fast fibre-optic broadband. The restart.]

  74. Doug Fleur says:

    Yup, App Store gets stuck on “Checking for updates”

    I guess I will not update for now, I don’t see anything worthwhile in the update anyway.

    • Dinky says:

      Killing softwareupdated will cancel the “check for updates” and you can then select what you want to update

  75. famiji says:

    Apple Discussion boards are full of complaints and problems with OS X 10.10.4, everything from crashing App Store to crashing Mail, to Mail no longer working with Gmail, to Wi-Fi dropping, to slow wireless networking, to crashing apps, to slow behavior. Apple even had a Public Beta with 10.10.4, what’s the deal??

    • Paul says:

      My MacBook Pro is working nicely since the update. There will always be some people that have issues with OS updates, they are very complex.

    • Rob says:

      No idea what the problem is. I tested each build of 10.10.4 before the public release (we are talking about over a month) and never had the problems people have been complaining about. the first builds had some Finder issues, but other than that each build of 10.10.4 has been stable and noticeablely better than earlier releases. Still no problems with the public release either.

      Sometimes I wonder if people have trouble because they have years of backdated files floating around in their systems, or never reformat drives by writing zeros to map out bad sectors before doing a reinstall of your OS.

      • Pab says:

        The MacBook Pro I have which encountered this issue is a mid-2015 model, about 2 months old, shipped with OS X 10.10.2 preinstalled, and there is very little third party software on it. So no, the problems are not limited to users with old files and crud floating around, this is a brand new Mac, hanging on an App Store update.

        • Edward Stern says:

          I have bening beta testing 10.4 also on my iMac no issues but I wiped clean my macbook air and reinstalled 10.3 to take on a trip. I could not upgrade it to 10.4 from the app store. had to go to apple downloads to upgrade. I had all the fan issues as well. very peculiar.
