Hannah BrooksReinstalling Rosetta 2 runtime daemon and rebuilding LaunchServices database.
Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:
- Force reinstall Rosetta 2:
softwareupdate --install-rosetta --agree-to-license - Reset LaunchServices database:
/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user - Kill daemon to rebuild fresh cache:
sudo killall -9 oahd
Following this procedure restores full stability with zero recurring log errors.
