I purchased this gamepad to work with Call of Duty Modern Warfare on my Mac in OS X, apparently it is 'plug & play', should be renamed 'plug & no play', very disappointing.
The Thrustmaster Technical Support answered my email very fast but didn't help much, this was their response..."The only detail you need to assure of is to check if the device is located on the official list of game pads that are supported by the game you intend to play. For this information we recommend you to get in touch with the developer of the game".
I wasted hours trawling the net looking for a solution and eventually gave up and continued to use the keyboard, which imo is not good for mac game play.
