Hello, scrollo.


Thank you for using Apple Support Communities.


I understand you're unable to install macOS update 10.13.6. I'd like to help. See if you can either update using safe mode or a test user account:


How to use safe mode on your Mac


How to test an issue in another user account on your Mac


If this doesn't help, try repairing your disk: Repair a storage device in Disk Utility on Mac


Keep me updated.


Cheers!
