At this stage I was thinking okay this has to be either the thunderbolt cable or the Interface has died on me somehow. Just today I tried the interface on two different 17-inch macbook pros of mine (one running High Sierra the other is El Capitan and it appears to get no power from either of them. Here's whats going on, I have a Zoom TAC-2 Thunderbolt Audio interface which I've been using for sometime with another macbook pro 17" and it had no problems on a macbook air either.
