Hello,
I have been trying to get OS X mountain lion 10.8.3 working with my hd 6850, but it is not working.
So far I have tried several kernels, kexts and different personalities, everything works but i'm still having artifacts.
Could you fix this with a dsdt for my motherboard.
Thanks in advance,
Quintes
