External USB Audio not being picked up by Macbook Pro I've just bought the brand new 13" Retina Macbook pro. I'd like to hook it up to my USB DAC (An Audio Engine D1) When I plug in the USB to the Macbook it doesn't pick up anything. I've restarted the laptop to no effect. Nothing is being displayed in the Output section of Sound in System Preferences. 

The DAC is supposed to be plug and play and has been working fine on my Windows machine for years.

How can I set up external audio on a Macbook Pro?
First, it would be helpful to know the exact model and the brand.

Second, could you please give this a try:


Plug your DAC in,
open the Audio-MIDI-Setup utiilty from the Utilities folder and 
check whether it appears?


If not, try to create a device for it... Just a crazy idea...
