Thank you for your suggestion. Unfortunately unable to follow safe restart as log in screen doesn't appear after steps followed. The Apple logo flashes on then replace by grey screen as before. Looks like it's trying to restart after software update, but then back to error screen as mentioned above.

Thanks but no good. I am unable to get to any menu. The screen shows as attached, then after the restart it eventually comes back to the same message. Have tried blind force quit etc, but just keep getting this. Help please! Thank you, I do very much appreciate your assistance. User uploaded file

We have had this happen on a few of our computers running High Sierra


This seems to fix it -


  1. When you get the message, click on the image inside of the error, you should now see a menu bar at the top of the screen
  2. Choose the Apple icon
  3. Choose Startup Disk
  4. Select "Macintosh HD" and restart/reboot
  5. Computer should now boot up normally
