How to clear font caches on MAC.

Description: Font Caches: The operating system and certain applications use font caches to keep track of installed fonts. Problems occur if a font cache becomes corrupted, for example: 

a) fonts not appearing in an application font list;
b) wrong fonts;
c)  missing fonts in documents. 

The best solution is to delete the font cache file(s). This is OK as they are automatically restored on system restart, or on re-launch of an application.
