Hi,


A Safe Mode boot deletes system caches that can help with problems due to an interrupted macOS update.



To start up in safe mode:


  1. Start or restart your Mac, then immediately press and hold the Shift key. The Apple logo appears on your display. If you don't see the Apple logo, learn what to do.
  2. Release the Shift key when you see the login window. If your startup disk is encrypted with FileVault.


To leave safe mode, restart your Mac without pressing any keys during startup.


Then open System Preferences > App Store then click: Check Now
