Hello!!! I used to work normally in a Apple Macbook Pro Retina 2015 13 i5, everything good, no problems with the hardware, working 'flawless' with or withour the ac adapter... and now i switched to a 15" Macbook Pro 2015 and i still can't record, i've been delayed a couple of days now. The interface keeps dropping out of ableton live, it nevers keeps a steady connection for more than 15 seconds... the other day i managed to make it work but ONLY without the computer's ac adapter.... so that limited my time, I tried to work the same way yesterday and now that wasn't possible. it does not work in port 1, in port 2, with AC, withput AC, it doesn't even show up half of the times. Please Help!!!!
