When I open Font Book there is a message in yellow "Multiple copies of this font are installed." That's the best I can get after several openings and closings of Font Book as the message flashes by so fast it's hard to read!
I have preferences set to Default Install Location: User and the box for "Resolve duplicates by moving files to the trash" checked.
I also selected ALL the fonts and checked for duplicates... there were none found... then I chose to validate all the fonts... no problems found except for 2 minor problems with one font. I disabled that one otherwise no problems.
Shut down Font Book... restarted it and there's the same message flashing by...
Happens even when there is no font selected.
Does anyone have any idea what the thing means?
