I don't understand why CCC will not allow me to enable crossfire. In the graphics tab there is no options for crossfire. Under the hardware tab it shows my second 5870 is disabled, however, in gpuz it shows that they are both there. Does anyone know how I would enable the second 5870? Or why this is happening. I never had this problem before, I downloaded the dreaded 10.12 and could not figure out how to enable crossfire, so I went back to 10.11 but I have the same problem. Any help would be appreciated thank you.

Is the jumper cable loose at all? I'd check that, then pop both cards out, then back in and give that a go... also I'd check the supplemental power cables. That's all I can think of.
