No Comments on Apple will stop accepting 32-bit Mac apps starting January 1, 2018

Apple recommends that if you distribute your app outside of the App Store

you should update your app to run 64-bit as well.


														
							

Apple’s Developer site has today shared a reminder that starting January 1st, 2018 32-bit Mac apps will no longer be accepted.

This is due to the fact that macOS High Sierra will be the last macOS release to support 32-bit architecture.

Apple also shared its support site for distributing Mac apps.

As a reminder, new apps submitted to the Mac App Store must support 64-bit starting January 2018, and Mac app updates and existing apps must support 64-bit starting June 2018. If you distribute your apps outside the Mac App Store, we highly recommend distributing 64-bit binaries to make sure your users can continue to run your apps on future versions of macOS. The last macOS release to support 32-bit apps without compromise is macOS High Sierra.
