My 2017 Macbook pro no longer will shutdown. It clears the screen to black and leaves a cursor pointer in the top left corner.....forever.
It was not such a big deal until I tried to use the appstore to upgrade to 10.13.6. After the upgrade shutdown notification it just hangs with the cursor in the top left. I can still manually power down, and I can still ssh into the box and do a sudo shutdown; But then the MACOS upgrade never happens.
Finally I booted into repair mode and restored the operating system from there (cmd,opt,R). The upgrade was successful, but alas I still can not shutdown the box without it going to the black screen with cursor.
Any ideas?
