Which really really really sucks, because Rosetta is amazing. it’s extremely performant at running x64 code on Apple Silicon, and I’ll be sad to see it go.
To Apple’s credit, though, they did extend its end of life a full year. Rosetta 2 Support was supposed to end this year with the release of macOS 27 Golden Gate, but due to enough backlash, they extended it to next year. (which they also did with Rosetta 1, back in the day.)
The real thing I’m pissed about is they won’t open-source it, which Apple sometimes does (or, used to do) with its tools.
