It doesnt work for the new macbook airs.

Whenever I try to play touchgrind on my new 2013 Macbook air, it says the touch pad does not support multi-touch gestures, and when I try tp play it, the game would glitch and bug out. Please let me play this game, it looks good and full of potential… If only I could play it.
