Creating an Admin Account in Single User Mode

Start by turning off your Mac. If you’re not able to shut down normally, press and hold the power switch.

Once your Mac shuts down, you’re going to restart it in a special startup environment called Single User mode, which boots your Mac into a Terminal-like interface where you can run commands directly from a prompt.

You can use Single User mode for many different troubleshooting processes, including repairing a startup drive that won’t start up.
