This is quick and dirty how-to to get Quartz Extreme and Core Image at full resolution working on OSx86 (with OSX 10.4.8) a nVidia 7600gt 256MB card.

Follow the simple insructions below and you can’t go wrong:

  • Install OSx86 with the optional Natit package
  • Once booted find your card identifier by adding the DeviceID and VendorID together to get a string (mine is 0x02e110de)
  • Edit the corresponding <string> tag for the IOPCIMatch key in these four packages
    • /System/Library/Extensions/Geforce.kext
    • /System/Library/Extensions/NVDANV40Hal.kext
    • /System/Library/Extensions/NVDANV30Hal.kext
    • /System/Library/Extensions/NVDAResman.kext

If the file is like this:

<key>IOPCIMatch</key
<string>0x00000000&0x0000ffff</string>

Replace it with this:

<key>IOPCIMatch</key
<string>0x02e010de&0x0000ffff</string>

If the key has a number of values in the string tag, just add 0x02e010de&0x0000ffff to the start of the list.

  • You now need to flush the kext cache so run:
    sudo rm /System/Library/Extensions
  • Now reboot and enjoy the goodness of Mac OSx86 :)

I cannot claim the credit for this, I got it from a post by sinjon on the osxx86 forum
