A couple days ago I created an unofficial Mac OS X port of the Cutie Mark Crusade Demo, and I decided that I might as well post it up here. For those of you who are tired of running the game through the command line and just want to launch it by clicking on an app, here you go!

Please note that this port is somewhat unstable, and I have no idea if it works for ponies other then me. Please leave feedback on stability in the comments.
