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