The Apple Rumor mill feeds on snippets from comments and documentation embedded in the code. Some of those refer to developmental technologies or branches that may never see the light of day, some of those are from the early macOS 12, 13, 14, even 15 development that is already ongoing, some from other offshoots from the underlying kernel, and some may really a harbinger of things to come. Given Apple's past history of migrating from one processor to another, I wouldn't worry about the disappearance of Rosetta any time soon. Certainly not before the entire Mac product line has been moved to Apple silicon, and that is still a year or so away. After that, it is certain to happen sooner rather than later. Not that rosetta will be removed from existing versions of macOS, just that it won't be included in future versions.


If we knew what it was we were doing, it wouldn't be called research, would it?
