View source for Mac: make an aggregated audio device (group 2 or more audio devices into one)

ATTN: this is for Mac only !

You may want to do this especially since on most Macs the audio output device (usually called "Built-in Output") and the audio input device - the microphone (usually called "Built-in Microphone") are separated devices, so you cannot use them at the same time in future.dj / FutureDecks DJ pro. So, you have to make an aggregate device from the 2 devices to be able to use both output and input (microphone) at the same time.

If you wish to aggregate 2 or more audio devices (make them into one) so they would appear as one single audio device here is what you have to do:

[[File:aggregate_step4_5.jpg|700px|thumb| center |Step 4 - a new "Aggregate Device" appears in the devices list -- simply select it and then enable (on the right) the "Built-in Microphone" and "Built-in Output" devices. After you checked (enabled) both the input and the output devices you then select the Clock Source as the "Built-in Output" device]]

That's all there is to it. You now simply open up future.dj / FutureDecks DJ pro and select the "Aggregate Device" in the Audio settings.
