I have an M-Audio Firewire Audiophile that I haven't been able to get working with my new C2D iMac. I'm using driver version 1.7.2, which according to the M-Audio website, was released for Mac OS X 10.4.6 - not 10.4.7. Anyone else having similar problems? I wonder if I'm going to have to depend on M-Audio to release a new driver for every single point update of the Mac OS.
