Good Morning All,

I recently updated my beloved MBP only to find a window telling me "The MacOS installation couldn't be completed" with options of shutting down or restarting. If I do either one, it pulls up the same window.

Has anyone encountered this? How can I just revert back and not install the update?

Do you have a backup from before you attempted this upgrade?

If you have a backup of your personal files to an external drive, you can restore the Mac to Factory defaults. Restart the MBP and hold down the Command+R keys to enter Recovery.
Connect to your WiFi.
You should see one of these options depending on your version of OSX, OSX Recovery, Internet Recovery, or Reinstall OSX.
