I am a MBP owner hoping to see an answer from SE for the Mac version in the future.

I can understand why BOOTCAMP isn't that good and Windows 7 had to take 2GB out of my RAM but ARR is still playable. I don't see why they are against OS X since it's based on UNIX like many features you see from Linux. If SE is making the game for the PS3 with OpenGL then it would not be that much problem for a established game company to port it to OS X and Linux.
