NOTE: THIS WORKS ON OTHER MODS ASWELL IF YOU ARE HAVING A FONT PROBLEM
What you want to do is to go to the textures of the mod and delete font.dds. Apparently, the fonts dont work on mac. Then once the game is loaded up you will be confused because there is a white screen. Now this is the only hard part. This is actually the home screen and you have to kind of guess and click on the left hand side of the screen for the load game and start game screens. After this the game is completely playable. If anyone can help find a way to deal with the white screen, then it will be completely playable and easy to use.
