Gamepad D-pad not working in game (Mac version)

My gamepad isn´t working properly in game. I can start up the game, I can use the D-pad and all the buttons in the meny and the world map but when I start the game the D-pad stops working. The buttons seem to work since I can jump, but I can´t move. This is kind of annoying especially since the splash screen states that I more or less would be an idiot for not playing with a pad.

Are there any knows work arounds for this or is there a patch in the making? A quick google search makes me realize that I´m not the only one with gamepad problems.

ps. The gamepad is a generic USB pad but since it works in every other context and even in Super meat boy (up to the game itself. I would rather have it the other way around...) the problem lies not with the gamepad.
