By disabling some of the extra fonts we can reduce the time applications have to spend on managing fonts. So how do you disable fonts? You can use the application Font Book that comes with your Mac (you find it in Applications). Give it a few seconds to load your fonts then go through the list and disable the ones you don’t use by selecting Disable from the Edit menu. Damaged or duplicate fonts can also slow down your computer so while you are in Font Book select Validate Fonts from the File menu and verify that the fonts you have installed are okay. You can automatically disable duplicates by using the Look for Enabled Duplicates (or Select duplicate fonts on Snow Leopard), followed by Resolve Automatically option (or Resolve Duplicates option in the Edit menu on Snow Leopard). It is also a good idea to enable Automatic font activation in Font Book’s Preferences as it lets OS X re-enable fonts when an application needs it. It is worth noting that the font caches themselves can become corrupted and cause slowdowns or crashes on your Mac so if you experience problems because of this it is a good idea to force OS X to rebuild the font cache. Cocktail makes this easy: open Cocktail and go to Preferences > Caches > User and select Font Caches. Next time you clear the caches Cocktail will make clear out the font caches too and force OS X to rebuild them.
