Open Source Mac Software

Open Source Mac

From the About:

Open Source Mac is a simple list of the best free and open source software for Mac OS X. We aren't trying to be a comprehensive listing of every open-source mac app, instead we want to showcase the best, most important, and easiest to use. This page should be a handy reference and a useful tool for getting more people to start using free and open-source software. If you think we're missing any great apps, please let us know. If you're a Mac user, this site is a treasure.

Not every open-source app, but the cream of the crop. Firefox (web) and Thunderbird (email) are here, plus about half a dozen more apps I use frequently. Nicely done!
