I just updated to Mac OS X Sierra and my TonePort UX2 doesn't want to open in my computer. I had no problems with it when I ran Yosemite. Any idea how to fix it? I downloaded the last driver update for TonePortUX2 still no luck so far. It could be just a simple tweak but I don't see it. If you ran into this kind of problem before I would appreciate your help. Thank you.
