Sapphire Dual-X R9 270x with 10.8.5

     I am given to understand that the R9 270x should work OOB with 10.8.5, however, when I load the OS system information shows:


VRAM (Total): 3 MB [Definitely not correct]
Vendor: ATI (0x1002) [This part seems correct]
Device ID: 0x6810 [This appears to correctly identify the series]
Revision ID: 0x0000 [Not sure?]
Kernel Extension Info: No Kext Loaded [i am assuming this is the primary issue?]



Anyway, I have been reading through this thread and other relevant info: http://www.insanelymac.com/forum/topic/294315-radeon-r9-270x-framebuffer-issue/ 


I somewhat grasp the concepts regarding kext editing and DSDT injection/modification (although not so much the hex code editiing), and I am attempting to learn all of this quickly, however, I am not sure that all of the relevant kexts are even present in S/L/E


I know that I have ATI7000Controller.kext and an X4000.bundle thing, but not an X4000.kext or AMDSupport (i think that's the name?)



I was just wondering if anyone had the full list of AMD/ATI graphics kexts that should be present in 10.8.5

Hey man, use framebuffer Hamachi. Works for me with dual-monitors too. No patch needed.


Hope I could help,
