No error messages, just black frames, if I turned the option 'use red rocket' off it worked.
I just changed the red rocket to the other slot in the Sonnet Echo Express Pro and it works now.
It's just like in the mac pro
Thanks for the tips guys!
Now I get 2 fps without and 12fps with RR in half premium. Should that be ok?
PS is there a release history of Resolve? A friend of mine claims he runs 9.0.3 on his Mac Pro 1.1 in Lion 32 bit? Could he?
