360 controller, Steam, Mac. I need help.

So I got this game Sportsfriends the other day that's supposed to be playable with any controller. But I CANNOT get my 360 controller to work. went to download drivers the developers said I should install, now the center light does even stay on where as it did with before. I can go through steam with it, but as soon as I open up the game itself, it's like the controller doesn't even exist anymore.

Extremely frustrated and need help!
