Does Rosetta take up much space, and can I remove it?
Short answer: Rosetta is small; its translation cache grows only with many large Intel apps. There's no supported uninstall, and it isn't worth chasing for space.
Rosetta lets Apple silicon Macs run apps built for Intel. It's small, and it keeps translated copies of the Intel apps you run, which add up only if you use many large Intel apps.
There's no supported way to uninstall Rosetta once installed, and it isn't worth chasing for space. Updating Intel-only apps to native versions removes the need for it over time.
