OK, I learned a few things. I installed a Radeon HD 7970 Graphics card in the mac pro (mavericks 10.9.1) and it’s still stuttering. Disabling audio in Resolve makes it play smoothly.
I found an old cloned boot drive and found Resolve runs super great in ML 10.8.5 with audio enabled. Over 30 fps. Problem is, I’ve already converted a bunch of FCPX 10.1 libraries. Looks like I’ll be going back to ML with the next project.
Anybody else getting Davinci Resolve to work on Mavericks? It’s got to work for the new Mac Pro, right?
