Deleting System data (Snapshots) 205GB
macOS Monterey 12.0.1 - My iMac (2019) system data is reading 205.28, that most likely are old back up snapshots which I would like to remove:
Time Machine unticked from auto back up = No change
Terminal command "sudo tmutil disablelocal" returns Unrecognized verb.
Are there any other functions to attempt?
