I just purchased a new MacBook Pro and migrated everything over from the old one. I had imagined that it was the old one that was preventing me from being able use Font Book (
Font Book.app); it’s not that.
When I attempt to open it on the new machine, looks like it is going to work for about five seconds, then becomes completely non–responsive, including the spinning wait cursor, until I use Force Quit.
So far I have tried deleting
~/Library/Preferences/Saved Application State/com.apple.FontBook.savedState, and
and then rebooting, but to no avail.
