Alex RosenbergWhen a future macOS kills Intel support, I’d like to keep Rosetta 2, if only for Virtualization of other OSes.
Fred Haineux@alexr Was it you that suggested Classic MacOS? I want to play all those old games.
Tim@alexr Rosetta 2 only implements ring 3 x86, so it can't virtualize a whole OS. Probably never will, since AIUI the emulator derives a lot of its performance from assumptions made possible by this limitation.
It may stick around anyways, as there's already use cases beyond running x86 macOS binaries. Apple somewhat recently added a version of it for use inside Arm Linux VMs, enabling them to execute x86 Linux userspace binaries. It's also used by WINE.
