Works with PS3 DualShock3 (wireless)
GamePad Companion seems to be working fine with my PS3 DualShock3 wireless controller connected to the Mac via BlueTooth (running OSX 10.7). It is easy to set-up multiple configurations and switch between them for different games. However, I havent had the chance to use or calibrate the analog R2 and L2 trigger buttons in, for example, a good racing game, so I cant say how well that aspect works.
