Some items in the Trash cannot be deleted because of System Integrity Protection That's the message I'm getting when trying to empty the trash. To my knowledge, almost all of this is just old backups from an external drive, even though the message seems to imply I've been rooting around (no pun intended) in operating system files.



Any clue what this message means?
sudo rm -rf /Volumes/ExternalDrive/.Trashes/


Replace "ExternalDrive" with the actual name of your external drive.
Be careful using the rm command and make sure the path to the External Drive is correct.
