Further instructions may ask that you try restart into recovery or other built-in system partition
in a troubleshooting attempt to repair or reinstall the macOS.
Learn what to do if your Mac starts up to a circle with a line through it (prohibitory symbol).
"A circle with a line through it means that your startup disk contains a
Mac operating system, but it's not a macOS that your Mac can use."
- Press and hold the power button on your Mac for up to 10 seconds, until your Mac turns off.
- Turn on your Mac and immediately press and hold both Command (⌘) and R to start up from macOS Recovery.
- While in macOS Recovery, use Disk Utility to repair your startup disk.
- If Disk Utility found no errors or repaired all errors, reinstall macOS.
- If you still need help, please contact Apple Support.
In general these instructions can help reinstall or repair/reinstall.
