Dropping Intel Support for Mac App Store Apps

If you maintain a universal Mac app, Apple now lets you drop Intel support on the Mac App Store, provided your app's minimum system version is macOS 13 or later. The 18 June App Store Connect release notes describe the change: remove the x86_64 architecture, then upload and submit the new build.

Apple also covers this in its WWDC26 App Store guide, which says apps offered as Universal Purchases no longer need to support Intel. The same macOS 13 minimum applies.

I think this is a welcome change, particularly for smaller developers who have to fit compatibility testing around everything else involved in shipping an app. Supporting another architecture means keeping a build working and checking how the app behaves on that hardware. That can be worthwhile work, but it's reasonable to review whether it still makes sense for your app.

The people using Intel Macs should be part of that decision. If they're a substantial part of your audience, continuing to support them may be the right choice. If you've mostly kept x86_64 because it was already in the project settings, this is a good opportunity to check your usage data and the maintenance involved before deciding what to support in your next release.
