Reinstalling 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:

  1. Force reinstall Rosetta 2: 
    softwareupdate --install-rosetta --agree-to-license
  2. Reset LaunchServices database: 
    /System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user
  3. Kill daemon to rebuild fresh cache: 
    sudo killall -9 oahd

Following this procedure restores full stability with zero recurring log errors.
