apple silicon – Implications of the assertion: “Word that it is rather troublesome to take away Rosetta 2 as soon as it’s put in”

Rosetta permits to run (64-bit) Intel apps on Apple silicon by translating the x86_64 directions.

Basic documentation about Rosetta from Apple may be present in In regards to the Rosetta Translation Surroundings.

How does Rosetta 2 work? offers some info the way it works underneath the hood.

Rosetta is troublesome to take away as a result of there isn’t any official uninstall methodology, and since the information put in by Rosetta are protected by SIP (System Integrity Safety) like different macOS system software program.

Inofficial directions tips on how to eliminate Rosetta may be discovered e.g. right here and right here, it primarily quantities to

• Getting the file record 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 threat. I have not examined it.

Comment: It’s a pity that Apple doesn’t present a way to take away (or at the least 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.
