Rosetta permits to run (64-bit) Intel apps on Apple silicon by translating the x86_64 directions.
Normal documentation about Rosetta from Apple may be present in In regards to the Rosetta Translation Atmosphere.
How does Rosetta 2 work? gives some info the way it works beneath the hood.
Rosetta is tough to take away as a result of there isn’t any official uninstall technique, and since the information put in by Rosetta are protected by SIP (System Integrity Safety) like different macOS system software program.
Inofficial directions methods to do away with Rosetta may be discovered e.g. right here and right here, it primarily quantities to
-
Getting the file checklist with
% pkgutil --files com.apple.pkg.RosettaUpdateAuto -
Booting into restoration mode to disable SIP.
-
Eradicating the information.
-
Enabling SIP once more.
Once more: These are inofficial directions, use at your personal danger. I have never examined it.
Comment: It’s a pity that Apple doesn’t present a way to take away (or not less than disable) Rosetta. I do know of a case the place some software program was inadvertently distributed as an Intel-only bundle as an alternative of a Common Binary. This went unnoticed as a result of Rosetta was put in on the pc the place the software program was examined.
