The default Eclipse for Mac OS X font is kind of annoying since it’s way too big and reminds me of MS Comic Sans. If you try to replace it with one of the wonderful ProggyFonts without tweaking them first, you get stuck with anti-aliased fonts that look terrible. During my quest to get past this problem, I came across a way to setup a more programming friendly font in Mac OS X which uses one of the Proggy Fonts in aliased mode.

Although the above instructions aren’t terribly explicit, you can find the various Eclipse font settings under Eclipse > Preferences > General > Apperance > Colors and Fonts once you’ve installed the font and made the appropriate changes to your System Preferences.
