Apple has notified developers that applications submitted to the Mac App Store that are universal macOS apps and require macOS 13 or newer can now be built without support for Intel-based Mac computers. This marks a shift from previous requirements where Intel compatibility was mandatory for universal apps.
The primary benefits for developers include simplified development workflows and optimized app download and on-device sizes. Developers can achieve this by updating their app build settings to "arm64" only, then rebuilding and resubmitting their applications to the Mac App Store.
While developers can drop Intel support for new versions, Intel users will still be able to use the last version of an app that was compatible with their machine. This ensures continued functionality for users who have not yet transitioned to Apple Silicon Macs.
This policy change is part of Apple's broader transition away from Intel processors. macOS 27, codenamed Golden Gate, is set to completely drop support for Intel-powered Macs. Additionally, Apple previously announced that Rosetta 2, the translation layer for running Intel apps on Apple Silicon, will be discontinued after macOS 27, with limited exceptions for certain games.
