Have run out of easy fixes on iMac that won't restart or shutdown
Running macOS 10.13.6 on iMac Retina 5K, 27-inch, 2017
Trouble started when I was trying to do Security Update 2019-002 10.13.6 tonight.
The restart/shutdown attempts usually proceed as follows:
- Screen blanks, leaving only the mouse cursor visible
- Then the mouse cursor disappears...then reappears. And that's as far as it goes.
- Have tried the PRAM reset and the SMC reset as well, but to no avail.
- Did a restore startup and ran Disk Utility First Aid on Macintosh HD. Everything A-OK there.
- No luck with other diagnostics. ("D" restart).
Maybe I should just throw in the towel and upgrade to Mojave....?
Though maybe I can't if the @#$%^& machine won't restart!
