Seems like a bug if it only affects certain processor cores.
- wickedOne 2y agoi 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
- bbatsell 2y agoThey 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.
- wtallis 2y agoVirtualizing 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.
