In this tutorial i will show you how to get working hackintosh graphics in mountain lion with Full resolution and QI/CE
previously i posted patched kext for lion 10.7.4 and this time this is for mountain lion 10.8.1 and laterafter installing everything ,  i am assuming that you already installed boot-loader and other kexts if you dont you should install them first, for more on installation guides see http://www.tonymacx86.com and get back here when you install everything except graphicsTESTED ON : Mountaion Lion 10.8.1

NOTE : I do not issue any guarantee that this will work for you! use google for other troubleshooting

STEPS :
1 : Open Terminal and paste these commands to ShowAll Files

$defaults write com.apple.finder AppleShowAllFiles TRUE
$killall Finder

2 : Figure out your graphics device ID
  • about this mac
  • more info
  • system report
  • click on graphics/displays from left sidebar

3 :Add your Device ID to ATi5000controller.kext and AMDRadeonAccelerator.kext.
  • GO to System/Library/Extensions 
  • then find one of the above Kexts and show package contents  
  • Contents 
  • add you dev id to info.plist under IOPCIMatch

    for eg . if your card vendor id is  0x1002 and devise id is 0x68f9 then

    <key>IOPCIMatch</key> <string>0x68f91002</string>

4: delete all ATI and AMD related Kexts and injectors EXCEPT these 5 : 
  1. ATIFramebuffer.kext
  2. ATIRadeonX3000GLDriver.bundle
  3. ATI5000Controller.kext
  4. AMDRadeonAccelerator.kext
  5. ATISupport.kext
or just copy and save all ATI and AMD related kext to somewhere and delete from S/L/E then download and install these patched kexts 
 
Download kexts

Another Patched Kexts if first doesn’t work for you ( 10.8.2 version ) 

 

5 : set GraphicsEnabler = Yes 
6 : Repair permission through kext utility 
7 : reboot
