Remove/Uninstall Rosetta 2 from Apple Silicon Macs

1. Obtain a list of files/directories and LaunchAgents with: pkgutil --files com.apple.pkg.RosettaUpdateAuto
2. Save them in a way that you can access them in the recovery
3. Boot into recovery mode: Press and hold the power button on your Mac until “Loading startup options” appears.
4. Open Terminal in recovery mode
5. Run csrutil disable and confirm (temporary disable SIP)
6. Reboot
7. Delete the files listed at step 1 (in my case it was enough to delete /Library/Apple/usr/share/rosetta and /Library/Apple/usr/libexec with all their contents)
8. Remember to empty the Trash
9. Reboot back to recovery
10. Run csrutil enable and confirm

Sample pkgutil output:

$ pkgutil --files com.apple.pkg.RosettaUpdateAuto
