Audio 2 dj / Audio 4 dj / Audio 8 and USB 3.0
Just wanted to double check here before swooping one of these second hand. I believe the USB 3.0 backwards compatibility issue has been resolved, correct? I’m running a late 2012 MBPretina 13in with only USB 3.0 ports…
Friendly bump 
If you are using windows 7 (havent tried on 8 yet) i wouldnt do it.. My audio 2 crashes the OS if I plug it in through usb 3. For MAC i have no idea. I got it to work on my laptop through the usb 2 slot ( i have one of those) but latley ive been having some troubles with this one too where windows doesnt recognize the audio 2.
In general I would advise you to borrow from someone to try first, if possible. From my experience with the NI soundcards + windows usage I would not recommend buying before testing. I would expect apple computeres to work tho, as most dj equipment is made with their OS in mind.
I use the Audio2 mk1 with my new MBPr. Everything works fine when set to 48 kHz!
NI released drivers for MacOS 10.9 & 10.10.
For a former MacOS version use the older drivers!
You find the drivers on NI´s support page.
Thanks Dr.Blue and Consul. Yes, I saw the drivers and downloaded appropriately. Will try to test the soundcard on my laptop before buying.
