I have at least 80 fonts that are not functional. They all are listed with six rectangles       beside their font name. How can they be deleted? My Photoshop is on a Mac.
I have opened Font Book within Launchpad and searched for the dysfunctional fonts but they do not appear there. Yet they do appear in the Photoshop font drop-down. I searched for the names of the dysfunctional fonts in fonts.adobe.com and they do not exist there.
I have not been able to delete them within Photoshop or Font Book. There are so many dysfunctional fonts that it really complicates efforts to select a font while using Photoshop. Is there a way to remove or delete unwanted fonts?
