If you've updated to macOS 26.4, you may start seeing warnings when launching certain apps, noting they won't be supported in a future macOS version. This applies to apps that rely on Rosetta to run Intel-based code on Apple silicon.
Apple announced that macOS 27 will be the last version to support Rosetta for most Intel apps. Full removal comes with macOS 28, expected sometime in late 2027 or 2028, so there's no immediate action required.
Now is a good time, though, to take stock of which apps on your Mac are still Intel-based. Open System Information from the Utilities folder inside Applications, select Applications in the sidebar, and click the Kind column to sort your apps by type. Intel apps will group together, making them easy to spot. If you prefer a cleaner interface, iMazing offers a free app called Silicon that does the same thing.
