official support for any macos version < ventura has been dropped (monterey support ended 2024-09-16) so i wonder whether apple will consider this a bug...

  Seems like a bug if it only affects certain processor cores.

    i guess there will be always a previous processor supporting something which the most recent doesn't. but when the bug report is regarding supporting a software version which they don't support themselves anymore, personally i don't think they will give it any priority

    They added custom instructions to Apple silicon to more easily emulate x86 behavior (e.g., https://developer.apple.com/documentation/virtualization/accelerating_the_performance_of_rosetta https://developer.apple.com/documentation/virtualization/acc...). They may have now removed them because their analytics say that Rosetta2 use on new devices is minimal.

      Virtualizing older macOS on M4 hardware has nothing to do with Rosetta 2. And it would be ridiculous for Apple to remove hardware features that Rosetta 2 relies upon before they're actually ready to retire Rosetta 2—that would force Apple to invest more software engineering effort in updating Rosetta 2 to work without those features.
