Did you know that the OnLive OSX app has its own built in drivers that work out of the box with your wired Xbox360 controllers? I found this to be fantastic, but I had already installed the tattiebogle.net controller driver it works, but it conflicts with OnLives use of the device so I couldn’t use it where I wanted to use it. There were no handy instructions on uninstalling them, so I did it manually. Here’s how: back-up and then delete the /System/Library/Extensions/360Controller.kext and /System/Library/Extensions/Wireless360Controller.kext directories from your mac (you’ll need to be root to do this.) after a reboot the driver is gone and OnLive will recognize it. hope this helps someone.
