Look at the Metal API...if it has compatibility to render to an OpenGL context with a version number as old as what QC uses, there is some chance.
FWIW, I wish Apple would spend more time making sure all of their OpenGL drivers are up to par, supporting as recent a version as they can. Aside from QC issues. Stop reinventing the wheel or spending time on stop gap measures. I know that efforts like this give a little hype and publicity but...I feel like I've seen this dog and pony show before with OpenCL.
