Xbox 360 Controller won't work

[Radawan]

I have a retina macbook pro with OS X Yosemite and using a wired xbox 360 controller. I am using the 0.12 tattiebogle driver and it works with my controller fine. My controller light turns on like it's connected to an Xbox. I have set up all the controls that I need for Dolphin under GCPad, Pad 2. But once I open a rom/iso, it won't read my controller. I don't understand why this is happening, and I don't think it has happened to anyone else.
