My PS3 Controller not reading right?

[dolphinmac]

I have mac. The emulator works fine, in game and all. However, my controller does not read the right buttons it should. Like if I press the left analog, it will punch with square action. It seems to randomly change up too. So sometimes down will be up, and left will be right. I'm running dolphin 3.0 the release, because none of the other builds would get me in-game.

Any thoughts? Thanks.
