Hi again... Sadly our testing of torque 3d for mac with the AFX addon we use did not yield good results at all. Game was barely playable at all, performance is very poor on mac mini and midrange MacBook. We are waiting for a better version of the mac engine before producing a mac version of the game.
We did try though, but they're just not there with the mac engine yet to make it worth our while doing all the porting.
Perhaps later this year. Also we are waiting on torque 3d for iPhone so the game could play on apple devices, that is due to enter beta this fall.
