Updating system caches mac os x
If you want to test your font in a real-life situation, and you are thinking about Adobe apps, well, then you can use the Adobe Fonts folder, and avoid cache problems from the start.
Congratulations: You do not need to read any further, you are done!
But let us assume you decided to test your font in an application like Text Edit or Word. Because installing a font with the same name as a previously installed one can seriously mess up your font caches.
So, you install it in the system by either opening it in Apple’s Font Book app, or by using a third-party font manager, or by simply dragging the font file into . Caches are collections of previously calculated data.
Likewise, font caches allow your Mac to speed up the use of installed fonts because all the stuff your Mac had to calculate to make your font appear on the screen, has already been done.
