Reinstall macOS - Apple Support
1) Start up your computer in macOS Recovery:
*On a Mac with Apple silicon: Choose Apple menu
> Shut Down, press and hold the power button until “Loading startup options” appears, select Options, click Continue, then follow the onscreen instructions.
*On an Intel-based Mac: Choose Apple menu
> Restart, then immediately press and hold one of these key combinations, depending on what you want to do:
*Install the latest version of macOS compatible with your computer: Option-Command-R.
*Reinstall your computer’s original version of macOS (including available updates): Option-Shift-Command-R.
*Reinstall your current version of macOS: Command-R.
2) In the Recovery app window, select Reinstall for your macOS release, then click Continue.
3) Follow the onscreen instructions.
4) In the settings where you select a volume, select your current macOS volume (in most cases, it’s the only one available).
