Before attempting to uninstall the Axe-Fx II "driver" from your Mac computer it is imporant to understand that the Axe-Fx II actually uses OSX's driver. When you download the OSX "driver" from our website you are in fact installing a set of files that allows the Axe-Fx to renumerate itself as a valid audio device to the operating system. That being said, you can find these files in /Library/Application Support/Fractal Audio/AxeFxII. The files are named axefx2load, axefx2load.hex, and axefx2unload. By removing these files you will successfully uninstall the Axe-Fx II "driver."
