Because the manual identifies this as a command that requires root privileges, we’ll type the following into Terminal and then press Return: sudo tmutil disableĪfter entering our admin password and pressing Return once again, we’ll find that Time Machine is now disabled on our Mac.

The functions offered by the latter category are usually available only via the Terminal and are often helpful during advanced troubleshooting. Reading over the list of functions, you’ll see options that range from the simple – turn Time Machine on or off – to the more complex – checking to see if a particular file or folder is excluded from a backup, manually associating a backup drive with a new source drive, and comparing two backups to see what’s changed.

All of Time Machine’s magic is controlled by tmutil, or Time Machine Utility.
