5MD works on Macs, didn't test the others though.
Edit: Some small glitches, when in a game and you try to select a class load out the class icons will be invisible until you mouse over them.
Edit 2: Also in tournament mode (tested on a dodgeball server) in the top left where I assume it'd show players left it shows a red and a blue %%.
Edit 3: I have a glitch that I think it just an issue with fonts on Macs. The main menu text is cut off, it's still readable just annoying. Tested on 16:10. 16:9, and 4:3 aspect ratios.
