I want to use my PS3 controller on my Mac to play Borderlands GOTY. I have a magic mouse and I hate trying to zoom in with it. I've tried Gamepad Companion but I can't seem to figure it out; it just doesn't want to work with me.

Does anyone have a clue as to how I can get my PS3 controller working on a Mac?

Get a PC.

Or get Crossover and use joystiq.

I'm looking for an under $500 solution, thanks.

You're not helping. I said I needed Gamepad for Mac for a reason, It's not "Gamepad for Mac but I'm willing to waste my time looking for CrossOver to use Windows, a sucky operating system, to make it work".
