I've updated two of my systems to 15.7.7, iMac & MacBook Pro, and have had issues with both updates. The update runs and then the systems seem to hang and the display goes black after a few hours with only the cursor active. Have waited over 12 hours for it to complete. Finally on both systems I have had to do a hard shutdown and restart to get the system to reboot. After reboot system seems to be fine and shows it has updated to 15.7.7.
Has anyone experienced this issue?
