Article Brief Description:
Apple stated at their 2017 World Wide Developer Conference (WWDC) that a future version of macOS would stop supporting 32-bit applications. This article has information about this, how it might impact you and includes a list of known 32-bit applications.

32-Bit Applications

Apple stated at their 2017 World Wide Developer Conference (WWDC) that a future version of macOS would stop supporting 32-bit applications. It looks like macOS 10.13 High Sierra will be the "last version to support 32-bit applications without compromises". Therefore, macOS 10.14 (due Autumn 2018) is most likely to just warn users that 32-bit apps will stop working in the future. And macOS 10.15 (due Autumn 2019) will be the first version to not support 32-bit apps at all. With the release of the macOS 10.13.4 update (29th March 2018) Apple's plans to remove 32-bit application support appears to have moved up. We assumed 10.14 would introduce the warnings and 10.15 would kill support but the warnings have already appeared in 10.13.4+ and support will probably be killed off as early as 10.14.

Mac App Store Applications

Apple has already begun preparations to prune the Mac App Store. From January 2018 all new apps submitted to the Mac App Store will have to be 64-bit and from June 2018, both new apps and app updates must be 64-bit. Any submissions that don't meet these requirements will be rejected. At some point apps that are still 32-bit and that have not been updated will be removed from the Mac App Store. If you bought a 32-bit app you should still be able to download it (on a version of macOS that supports it) but no new purchases will be allowed and they will not show up in searches.

Apple Applications (Mac App Store)

As of 19th April 2018 all of Apple's current applications on the Mac App Store are 64-bit except for Compressor. However, be careful if you are still running very old versions of their apps such as early versions of Pages and Numbers.

Other Apple Applications

The following Apple applications are 32-bit. It is unknown if they will be updated to 64-bit:
  • DVD Player v5.8
  • iDVD 7.1.2
  • iPhoto Library Upgrader v8.1
  • QuickTime Player 7
There are some additional buried system apps/background processes that Apple includes within macOS that are still 32-bit. We haven't listed all of those here as one would assume these will be updated in the version of macOS that stops supporting 32-bit apps, but just in case here are a few:
  • /System/Library/CoreServices/SecurityFixer.app
  • /System/Library/Frameworks/QuickLook.framework/Versions/A/Resources/quicklookd32.app
  • /System/Library/Frameworks/Tk.framework/Versions/8.4/Resources/Wish.app
  • /System/Library/Input Methods/InkServer.app
There are, obviously, many old Apple utilities that 32-bit so we only list a few significant ones here that you might come across on your hard disk if you've migrated up from earlier versions of macOS:
  • iPod Reset Utility 1.0.2
  • Apple application based Read Mes and Guides
    • Apple Hardware Test Read Me 1.1
    • Apple Remote Desktop Administrator's Guide
    • Apple Remote Desktop Read Me
    • iDVD Getting Started 3.8
    • iMovie Getting Started 1.0.2
    • Keynote User Guide 1.0.2
    • Pages User Guide 1.0.2
    • Welcome to Leopard
    • Welcome to Snow Leopard

Third Party Non-Mac App Store Applications

32-bit applications will continue to run until macOS 10.15 (due Autumn 2019) is released. At this point if you still wish to use 32-bit applications you will not be able to upgrade to macOS 10.15. If you still run macOS 10.14 it should be supported with security updates until Autumn 2021. As of 29th March 2018 with the release of macOS 10.13.4 Apple's plans to remove 32-bit application support appears to have moved up so it is likely 32-bit applications will continue to run until macOS 10.14 (due Autumn 2018) is released. At this point if you still wish to use 32-bit applications you will not be able to upgrade to macOS 10.14. If you still run macOS 10.13 it should be supported with security updates until Autumn 2020.

Disc Burning Software

Many (all?) disc burning applications appear to be 32-bit including Apple's own iDVD - perhaps the underlying OS frameworks/components for this technology are only 32-bit? However, as Apple hasn't shipped any computers with a built-in optical drive since 2011 it is a possibility that Apple may not bother to update these underlying frameworks/components, which could mean the demise of disc burning directly within macOS, even on older hardware in the future! We'll update this article as more information becomes available.

Timeline For 32-Bit Applications

Based on currently available information this is the most likely scenario:

Early 2018 (macOS 10.13.0 - 10.13.3) - no change
Spring 2018 (macOS 10.13.4 - 10.13.6) - 32-bit applications will run but you will get warnings when opening them
Autumn 2018 (macOS 10.14) - 32-bit applications will not work in macOS 10.14 or later
Autumn 2020 (macOS 10.16) - macOS 10.13 will be unsupported for security updates so continuing to run macOS 10.13 with 32-bit apps will be a security risk!

The Way Forward

Although, at the time of knowing 32-bit app support will stop, there are a number of years before 32-bit app support will actually stop, it is always best to start planning ahead now. Create a list of 32-bit apps that you are running/have installed on your computer (see next section) and make plans:
  • Do you still need the application?
  • Can you update the application to a newer version for free?
  • Can you upgrade the application to a newer version? - this might have compatibility issues that need to be tested and/or associated costs that need to be planned for
  • Is there an alternative? - this might have compatibility issues that need to be tested and/or associated costs that need to be planned for
  • Consider moving older apps to a dedicated older Mac specifically to run them.
  • Consider virtualising an older version of macOS / OS X / Mac OS X with Parallels Desktop / VMWare Fusion / VirtualBox to run your 32-bit apps:
  • We recommend running the following versions of macOS / OS X / Mac OS X as Virtual Machines:
    • Mac OS X 10.6 Snow Leopard (Server) - costs money but you may already be running/want to run this to be able to use PowerPC/Rosetta based applications
    • OS X 10.7 - OS X 10.8 is better
    • OS X 10.8 - costs money but if you already own it/want to pay for it, it runs very efficiently in a virtual machine and there are few internet/iCloud based services clogging it up
    • OS X 10.9 - was very kludgy and slow when installed on a hard disk
    • OS X 10.10 - was slow when installed on a hard disk, does not support latest Apple internet/iCloud based services
    • OS X 10.11 - free, supports most internet/iCloud based services
    • macOS 10.12 - free, supports most internet/iCloud based services
    • macOS 10.13 - buggy, slow, still being revised by Apple, 10.13.4 or later will give you repeated running 32-bit application warnings

    How To Tell Which Applications You Have Installed Are 32-Bit

    Go to Apple menu > About This Mac > click the "System Report…" button (the System Information app will open) > select "Applications" under the 'Software' heading on the left > click on the "64-bit (Intel)" column heading to group applications > check the items listed as "No" in the '64-bit (Intel)' column. This can take a few minutes if you have a lot of applications installed/slow storage e.g. a traditional spinning hard disk. There are also a few third-party utilities out there that may help too: You should also consider that you may have background processes running that are 32-bit. You can see these (when they are running) by going to Macintosh HD > Applications > Utilities > Activity Monitor > CPU tab > (right click the column headings to add/tick the "Kind" column) > click the "Kind" column heading to sort by 32-bit/64-bit type.

    List Of Known 32-Bit Applications That You May Still Be Running/Have Installed

If a 64-bit version of a listed app is available we'll try to list it with a link. This list will be updated over time - bookmark this article and revisit it if running 32-bit applications is important to you.
