First Aid Utility
I have been running the First Aid utility on an external backup disk, and it seems stuck on ‘Checking catalogue file’. How do I get out of the utility as the ‘Done’ button is grayed out?

If the external backup drive is large, it could take some time. It is best to let Disk Utility First Aid finish on its own. Be patient, go do something else and forget about it for a while. Check back at a later time to see if it has finished.
