Jun 1, 2018 - 36 Comments

macOS High Sierra  update

Apple has released macOS High Sierra 10.13.5 update for Mac users running the High Sierra operating system.

Additionally, Apple has also released Security Update 2018-003 Sierra for macOS 10.12.6 and Security Update 2018-003 El Capitan for Mac OS X 10.11.6.

The new Mac software update includes mostly bug fixes and minor enhancements to the Mac operating system, but also includes MacOS High Sierra support for the Messages in iCloud feature, which is also now available for iPhone and iPad devices running iOS 11.4 (or later). Messages on iCloud requires that newer iOS build to be running on those devices, and Messages in iCloud must be enabled in iOS Settings in order for the feature to work as expected across iOS and macOS.

How to Download & Install MacOS 10.13.5 High Sierra Update

Mac users currently running macOS High Sierra can find macOS 10.13.5 available now as a software update:

  1. Go to the  Apple menu and choose “App Store”
  2. Choose the “Updates” tab and click to download and install MacOS High Sierra 10.13.5 when it becomes available

For Mac users running macOS Sierra or Mac OS X El Capitan, instead they will find Security Update 2018-003 Sierra, Security Update 2018-003 El Capitan available to download in the Mac App Store Updates section instead.

Security Update 2018-003

Mac users will also find updates available for iTunes 12.7.5 available to download and install.

Some more advanced Mac users may prefer to install the Mac OS software update by using the Combo Update packages, or manually download and install the Security Update packages on Macs running El Capitan or Sierra. Each of those individual package installers can be downloaded directly from Apple here at their support downloads webpage.

An added note: users who want to have iMessages in iCloud work as expected need to manually enable Messages on iCloud on their iPhone and iPad as well, after installing the iOS 11.4 update on their devices. Messages in iCloud is not expected to work on earlier versions of macOS system software prior to macOS High Sierra 10.13.5.

    After last update to 10.13.5, my MBP 2011 wan’t restart and doesn’t shut down anymore.
    In the App store will be listed: please restart
    and this will not change.

  2. Adam says:

    Hello I currently have installed sierra 10.13.4 and downloaded 10.13.05. When I proceeded to install the upgrade there was a prompt:mac Os High sierra 10.13.5 update cant be installed on this disk. This volume does not meet the requirements for this upgrade.
    Now reading the pre requirements the website says it requires 10.13.4 as a pre-requirement.
    What are the options to solve this problem I had earlier downloaded 10.13.6, however did not realise the pre requirement was sierra 10.12.5 and this is why I downloaded this version.
    The SSD is new and has 375.55 GB available.

  3. david corkran says:

    I found the update to be unstable on my 2011 i5 mini with a 1tb Samsung ssd. It crashed during the update and then I would get screen locks. Hard restart resulted in a white screen lockup. Would reboot after using recovery and selecting the start up disk. This became progressively worse over the last 5 days. Just performed a system reinstall through recovery. My 2012 i7 MacBook Pro hasn’t crashed yet but I have noticed screen flicker. I have not installed on my 2012 i7 mini and will hold off on it till apple fixes this. I have found similar complaints on line.

  4. ForGudnessSake says:

    After this update 10.13.5 with has stability and performance update, my mac mini niw is unusable at all. It keeps freezing my screen for every click like 30s freeze then cooldown like 10s the it will freeze again, thought background processes still continue to work after the freeze. I can’t even use activity monitor, but it has a complete user throttle usage god damn update.

  5. Charles says:

    After hitting update to 10.13.5, my iMac wan’t restart and doesn’t shut down anymore.
    The only way to shut down is pressing the on/off button for 8 seconds.
    Great Job(s)…:-(

  6. Ugo Possenti says:

    After the update (on my Mid 2013 MacBook Air) the text fields all across the OS (and apps) are painfully lagging. Does anyone have the same problem?

  7. Pete says:

    My Macbook Pro 13 refused to do a restart or a shutdown after I updated to 10.13.4 and continues to do so after I have just updated to 10.13.5. I need log out and then manually press the power button in order to shut the Macbook down. Apple software sucks these days.

    • BertusS says:

      I have same issue after the last update 10.13.5 High Sierra.
      is there anyone with this issue in the MBP 15″ of 2011?

  8. Lee says:

    lol lol people are still using that Beta software. “down”grade to 10.12.6 and all works ok

    • Daniel says:

      I know what you mean. I made the mistake of buying a new mac to replace an old ’08 machine. It was the first time I was disappointed within 48 hours of the unboxing. Unfortunately, I can’t downgrade the OS to something stable.

      It makes me sad that newer mac users can’t experience the “good old days” of Snow Leopard.

  9. Jeff says:

    I updated with this, and now all my seagate hard drives aren’t being seen. Disk utility sees them, but finder doesn’t…

  10. Wayne says:

    Ran the latest June 2018 Hi Sierra update. Boots up slow and hangs. Had to turn off and restart.

  11. Victor says:

    Ran the update on a Mid 2009 iMac. the 800 Firewire quit working. Any clues ?

    • opinion says:

      My strong opinion is that High Sierra is broken beyond repair, use at your own peril. I personally refuse to use High Sierra of any version on any production hardware, it is too problematic and the potential for downside is much higher than an upside of which there is none for me or anyone I know, there is literally no feature in High Sierra that I can even think of let alone something that would be worth any potential of the hassle. I go with El Cap and Serra instead.

  12. Calypso says:

    This update removed both my adblocker, and anti-tracking extension from Safari, so I had to install them all over again.

    • John says:

      I’ve ran the standalone installer and hadn’t noticed any problems with Safari extensions. Everything works fine as expected.

      Having encountered boot failures with APFS I’ve reverted my hard drive back to HFS+. Apple should improve their new file system and make it compatible with Fusion SSDs as the reports for crashing issues with APFS-formatted drives constantly grow.

    • Deb M says:

      I found the same problem. My adblocker and duckduckgo were both eliminated. I hope to figure out which adblocker I had installed… I’m not a computer/tech wiz… but I’ll keep investigating!

  13. iMac convert says:

    Asked many times, does anyone know where the amount of data an Apple update can be checked before download?
    Its important to those that have limited data package.
    It is never shown anywhere I check!

    • Calypso says:

      As far as I know, there is now way to know, until you start downloading. You can start a download, take a look at the progress bar, and if you see that it takes more than you can allow to use up, cancel the download.

      • Tom says:

        Hi, I just installed the 10.13.5 update on my MBPr 13 Mid 2014, the size is 2.12 GB. It took about 25 minutes including small updates for Numbers, Pages, Keynote and DaisyDisk. Everything seems to be running correctly.

  14. M Schumacher says:

    This update is just crap. My battery drains from 100% To 5% in 1-2hours, whilst before I could use it 6 or more hours Watching movies or series And still have battery left

    • RK says:

      I have the same issue. My Macbook battery drain is drastic after this upgrade. Anyone any tips to prevent it ?

    • Peter Z says:

      Same, I upgrade yesterday. My MacBook Pro 15″ Retina lasted me all day on battery.
      Now I have to re-charge every couple hours.

    • Sean says:

      Weird, because I’ve had the opposite experience! The last update, 10.13.4, had my 2017 MBP running super hot (70-80ºC), forcing me to run the fan at 7200rpm all of the time, and killing the battery in about 2-3 hours. Very frustrating!

      Since this update, my fan has been off, temp. has been at ~45ºC (maxed at 50ºC), and after an hour of use (Photoshop CC, Acrobat, Chrome, iTunes, and Word, all running simultaneously) my battery has only dropped to 10%.

      I wonder what could cause such extreme, opposite experiences for multiple users?

  15. Cody Staples says:

    What is the difference between a combo update package and a regular download.?

    • Paul says:

      The Combo Update is a more complete update installer, and it therefore allows you to go from say macOS 10.13.3 directly to macOS 10.13.5 without installing the in-between software release (in this example, 10.13.4). It’s most useful for people upgrading from earlier versions within the same major release, but running a Combo Update package can also sometimes remedy a failed update process, and some power users just prefer them for various reasons.

  16. DJ Sullivan says:

    Hello. If you are like me and prefer to use Combo Update or direct download packages to install yourself (download once, install multiple Macs, or download and maintain package file library, etc), then the following links may be useful to you. They all are from Apple for this particular update grouping to macOS High Sierra, Sierra, El Capitan.

    “The macOS High Sierra 10.13.5 Update improves the stability [and] performance…of your Mac”

    I’m not actually convinced this is true until they provide any evidence to back it up. If they really did improve those things, why not put it in the changelog?

    • MacHelper says:

      Looks like your glass is always half empty.

      • avenged110 says:

        Years of unreliable software will do that to you…

        • INWDC says:

          Agree with avenged110. There’s no denying Apple’s software quality has dropped considerably in the past 5 years. Sadly, the average consumer has only two choices: apple or windows. And until Linux or some other OS maker hits it out of the park, then we’re basically at the computing mercy of these two turds.

    What happened to promised APFS support for hybrid drives?
