I normally use a PC with a RAL dual conduit cable w/ IFI usb power connected between my dac. I'm experimenting with a Macbook Air, and for some reason I can only get the cable working when both the data and power conduits are connected to each of the Macbook Air's 2 usb ports. I cannot get it working with IFI power supply. Any ideas why this might be.
Is there something in the MAC OS that I can change so that my dac is recognized?
