As announced in September, macOS 27 Golden Gate is now available to users whose Mac will support the upgrade. However, Apple has recently announced that it will be changing their support model for apps that require Rosetta to run Intel-based applications.
What is Rosetta?
Rosetta allows Intel-based apps to run on Apple silicon devices. In 2020, Apple announced the transition from Mac computers with Intel processors to Mac computers with Apple silicon. To ease this transition, Apple created Rosetta. Rosetta works in the background to translate Intel-based apps for use with Apple silicon. Rosetta is available for any Mac with Apple silicon using macOS 27 or earlier. Rosetta support will be unavailable with the release of macOS 28.
What does this mean for you?
If you run applications or services that require Rosetta, you could see an impact if you upgrade to macOS 27. Before upgrading, please check your apps for compatibility with this new operating system.
Apple has installed tools in macOS 27 to help users identify their Intel-based apps and prepare for the transition away from Rosetta.
