This keeps getting posted and is not true. Rosetta is still present and working. It throws a deprecation warning notice but otherwise runs fine.

It's macOS 28 that will no longer run x86_64 apps, although games are exempt. Rosetta is basically going game only at that point. They haven't announced how long it will keep working in this capacity.

Have they announced how they’re going to make it game only? A whitelist based on a hash of the executable? That seems cumbersome.

The basic answer is ability to run x86_64 will still be there, but the system frameworks (apart from like OpenGL shims etc.) will no longer be shipped with x86_64 slices.

The macOS 27 release notes explain how to activate this mode. `game-test-tool`

My guess (without much to substantiate it) is that it will also keep support for running x86_64 programs in virtual machines via `container` too.

That’s correct, Rosetta for running x86_64 binaries in Linux VMs is not going away. They’re no longer branding this feature as Rosetta, so it doesn’t get lumped in with the Rosetta removal for Mac binaries (although it’s all still kinda confusing)

Aha, thanks for the reference. Good to see that written down by Apple!
