Since the official Apple forum blocked me from posting, I will post here. I'm so disgusted that Apple did not provide support for NVIDIA graphics cards. What kind of crap is it that we are forced into buying underpowered second rate AMD cards in our Mac and then when given the possibility to use powerful NVIDIA GPUs, Apple blocks us again... Why does AMD have such sway over Apple? Who is sleeping with who? The promise of eGFX was to allow Mac users to break out of the limits of Mac Hardware. The kext files/drivers already exist, this is easy for Apple to enable. Hoping Apple opens the door to NVIDIA cards in their eGFX, until then I won't be getting an eGFX unit for my MacBook Pro, which I had planned to do. It also keeps me looking at a PC where I can run NVIDIA. Bring the rain!
