Apple Says macOS 27 Will Be the Final Release to Support Rosetta

Apple has confirmed that macOS 27 will be the final release to support Rosetta, bringing its transition away from Intel-based Mac apps closer to an end. In a developer update on September 1, the company said Intel-only apps will no longer run on Apple silicon Macs after macOS 27.



Users running macOS 26.4 or later may receive a system notification when launching an app that relies on Rosetta, alerting them to update to a native Apple silicon version. Intel-only apps will continue to run through macOS 27.


Notably, Apple says it will retain some Rosetta functionality for older, unmaintained games that rely on Intel-based frameworks, providing an exception once broader support ends.

Developers still shipping Intel-only software are being urged to begin the transition immediately. Apple recommends building and distributing apps as universal binaries, allowing them to run natively on both Apple silicon and Intel-based Macs. Developers that already offer an Apple silicon version should encourage users to install it to avoid the macOS 26.4 notifications and ensure their app runs when the transition takes place.

macOS 27 supports only Apple silicon Macs.
