fisherwei Posted September 1, 2014 Share Posted September 1, 2014 I copied yosemite's amd8000 and amdx4000 to 10.9.4, and add my card's dev-id into infos.plist. Then, resolution and QE/CI is working fine. But, Heaven extreme profile test will freeze mac os x, I have to reboot, "basic profile" is no problem. I also tested World of Warcraft, it is running OK, but the performance seems no good, there is only 25-30fps with the highest graphics settings. My another HD6850 can get same fps in mac os x .... Anybody have the same issue? Link to comment Share on other sites More sharing options...
vusun123 Posted September 1, 2014 Share Posted September 1, 2014 You shouldn't copy kexts from a higher version of OS X to an older version. It tends to mess up, and AMD kexts in 10.10 are still in developing stage, so it isn't stable. What bootloader are you using ? Link to comment Share on other sites More sharing options...

Rampage Dev Posted September 1, 2014 Share Posted September 1, 2014 Considering that your GPU is not supported in the OS version you are using and most likely you never enabled AGPM for the GPU be grateful that Apple and AMD have put in any amount of time into making a GPU they don't use under Mac OS X the ability to work.
