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.

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)

All Apple applications currently on the App Store are 64-bit except Compressor v4.3.2.

Other Apple Applications

The following Apple applications are 32-bit. It is unknown if they will be updated to 64-bit:
  • Compressor v4.3.2
  • DVD Player v5.8
  • iDVD 7.1.2
  • iPhoto Library Upgrader v8.1
  • QuickTime Player 7
There are some additional apps/background processes that Apple includes within macOS that are still 32-bit. We haven't listed those here as one would assume these will be updated in the version of macOS that stops supporting 32-bit apps.

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.

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:

Autumn 2017 (macOS 10.13) - no change
Autumn 2018 (macOS 10.14) - 32-bit applications will run but you will get warnings when opening them
Autumn 2019 (macOS 10.15) - 32-bit applications will not work in macOS 10.15 or later
Autumn 2021 (macOS 10.17) - macOS 10.14 will be unsupported for security updates so continuing to run macOS 10.14 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 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 Mac OS X with Parallels Desktop / VMWare Fusion / VirtualBox to run your 32-bit apps:

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.
