Installed font not showing up in keyboard preferences list
I have been trying to install a downloaded greek font, and have tried two - one is Galatia SIL and the other is SBL Greek. They have both installed into font book, but I cannot find them anywhere in my keyboard preferences list, including in the "other" category. How can I get Keyboard preferences to see these installed fonts? In Font Book, they are showing up in a folder called User. Thank you.
