If you need to uninstall Rosetta 2 on a Mac, here we show you how to uninstall Rosetta on Apple Silicon M1, M2 and M3 Macs.
Rosetta 2 is a clever free tool in macOS that “translates” Intel only apps and programs so that they work on Apple Silicon Macs.
Rosetta is not installed by default on Apple Silicon Macs and you’ll only be prompted to install Rosetta on a Mac the first time you open an Intel only application or program that requires it.
Most people will never need to uninstall Rosetta 2 after it has been installed.
However, if you’re using a Mac for testing, development or are a system administrator, you may need to remove Rosetta 2 from a Mac to see how certain apps and software performs without Rosetta installed.
Unfortunately, there’s no easy way to uninstall Rosetta 2 from a Mac because it installs deep within macOS and once installed, is SIP protected by macOS for security reasons.
This is why if you’re using a Mac for testing purposes, it’s much better to use a Virtual Machine (VM) such as Parallels.
Although Parallels is most commonly used to install Windows on a Mac, you can also use it to install macOS in a virtual environment that you can then easily install, uninstall and wipe the installation without affecting your Mac.
Shut down your Mac and then Boot into recovery mode by holding down the power button on your M1/M2/M3 Mac
Open Terminal and run the command csrutil disable and confirm to temporary disable SIP security on your Mac
Shut down and reboot your Mac normally
Delete all of the the files listed earlier making sure you delete /Library/Apple/usr/share/rosetta and /Library/Apple/usr/libexec and contents.
Shut down and reboot your Mac in Recovery Mode by holding down the power button again.
Run csrutil enable and confirm to complete uninstalling Rosetta from your Mac.
You have now removed Rosetta 2 from your Mac.
You can check whether Rosetta has been fully removed from your Mac by going to the Apple logo in the top left corner of your Mac and selecting About This Mac and then click on System Report and in the left hand margin select Software > Installations.
If you scroll down to “R”, you should not see any references to RosettaUpdateAuto which means that Rosetta has been removed from your Mac.
