Hackintoshers everywhere rejoice: Mountain Lion supports AMD Radeon HD 6950, 6970, and NVIDIA 5xx graphics cards without hacks.
A forum post on tonymacx86 claims the Radeon HD 6950 and 6970 cards work without hacks citing reports originating from netkas.org forums. There a number of users have reported the 6950 running Netkas EFI working natively in 10.8. While one user even experienced the 6950 working in Lion with unhacked drivers after a warm boot back into Lion from Mountain Lion, another tonymacx86 poster warned “he 69xx situation seems a bit immature and experimental at this point. Even in the new OS.”
Other users on Netkas have experienced problems notably with iTunes causing a kernel panic. NVIDIA’s 5xx cards reportedly work natively without hacks or mods as well with tonymacx86 forum member mkchis claiming the GTX 570 is working faster than on his hacked lion system.
Sadly AMD’s latest card the 7970 isn’t even loading a driver in Mountain Lion. But, Robservatory has a workaround for those experiencing kernel panics when running Mountain Lion in VMware Fusion:
- Make a snapshot of your current setup!
- Run the VMWare Tools installer, but do not reboot when it’s done. Just leave the installer running onscreen.
- Navigate to /Library > Application Support > VMware Tools.
- Delete vmmemctl.kext and vmmemctl
- Edit (you’ll need root power) services.sh in that same directory.
- Comment out these two lines (they’re shown commented out, via the # in front of each):
- #kextload '/Library/Application Support/VMware Tools/vmmemctl.kext'
- #'/Library/Application Support/VMware Tools/vmmemctl'
- Save the edited file, quit the editor, and now (via the still-running Installer) reboot the virtual machine.
