    Today I tried using two external displays with my rMBP, but no matter what I do, I can only get one to work at a time. I'm on Sierra beta (10.12.1 Beta (16B2338c)) I'm using Thunderbolt > HDMI connections for both. When plugged in separately, they work just fine, but when I plug them in at the same time, only one works - the other isn't even recognized. I can swap them to get one to work and not the other, and vice versa, but nothing to get them both on at the same time.

    Apple support was of little help, and we collectively ran out of options. Anyone having similar issues or know of a fix? Any help is appreciated.
