Hello, I'm using an hackintosh for 3d rendering. I use Blender with Cycles render engine which use gpu for render the scene. In my system I have one quadro k2000 for manage monitor and viewport and 3 titan for gpu compute. Under Windows into nvidia control panel I can deselect k2000 from cuda compute, but with OSx 10.9.0 I didn't found any option like that. I can't choose which gpu exclude from Blender. Does anyone know a solution?
