Reinstall macOS from Recovery.

How to reinstall macOS - Apple Support


Reinstalling macOS does not erase your user data.  The only time that would happen is if you choose to delete, erase, format or partition your startup drive.


If you simply select Reinstall macOS from the macOS Utilities window, the OS should be reinstalled on top of the current installation, thereby refreshing the macOS version currently running. That is assuming that the drive device and volumes are healthy.


If you have not backed up your Mac, then this may be a hard lesson if things go sideways.


To non-destructively reinstall macOS as a troubleshooting measure - without deleting user files, documents, pics and vids, etc. – boot your Mac in Recovery mode by restarting and when you hear the startup chime press the Command-R (⌘R) keys until you see the Apple logo and progress bar. Use a wired USB keyboard for this.


Follow the onscreen instructions to “Reinstall macOS…”.


NOTE– You should not have to delete, erase, format, partition or otherwise alter your startup disk for this. If that becomes an option, quit the process and restart your Mac. Then come back here for additional advice.
