Sorry for the Zombie thread, but I figured something out in regards to this issue. for some reason, my Mac wouldn't connect regardless of which cable I used or which port I plugged it into, which order I powered on, etc. I just remembered that one time I read that some devices need to be run though an adapter because of the way apple connections work with other, maybe less high-quality connections, function. I plugged it into a random dock I had laying around and the helix connected. repeatedly. This seems to have fixed this specific issue when trying to connect.
Hope it helps someone.
