toolbox1234 Posted March 17, 2011 Share Posted March 17, 2011 I used to have a working 10.6.4 with a GeForce 7900CS card. Recently, the 7900cs broke and I got a GT430 to replace. However, I got KP whenever I try to boot it up. Boot up with -x switch also ends in KP. Any suggestions? Thanks. Quote Link to comment Share on other sites More sharing options...
Gringo Vermelho Posted March 17, 2011 Share Posted March 17, 2011 Fermi architecture video cards are not supported on 10.6.4 and lower. Boot into safe mode with -x, update to 10.6.6, install the latest drivers from nvidia and use GraphicsEnabler=y in /Extra/com.apple.Boot.plist.

Boot into safe mode with -x, update to 10.6.6, install the latest drivers from nvidia and use GraphicsEnabler=y in /Extra/com.apple.Boot.plist. Can not boot into safe mode. When using -x, the same "computer needs to power down..." message shows up. Quote Link to comment Share on other sites More sharing options...
pgb64 Posted March 18, 2011 Share Posted March 18, 2011 Hey toolie, sorry could not resist. I have a Zotec GTX 460 1GB, and it runs perfectly well on 10.6.3, and now on my 10.6.6. This is what I did, try it I hope it works for you as well. In windows use gpuz to dump your graphics bios. Change the name to Nvidia.rom. Boot into Mac copy the bios to the root of your Mac HDD. Remove all graphics injectors. In S/L/E copy this file to your desktop. NVDANV50Hal.kext . Modify your .plist with your hardware and device IDs. Use kexthelper to install this kext back to S/L/E. Make 2 copies of your com.apple.Boot.plist. Use OSX86Tools and make a custom EFI string with your Cards make, model, ext.. . when you are finished the wizard, you have 2 windows. The top one is the plist info ** do not use **. The bottom has your EFI string, leave the window open. Now open your com.apple.Boot.plist, and ADD these lines in red at the bottom, above the last dict and plist. <key>PciRoot</key> <string>4</string> <- add your cards pciroot here. <key>UseNvidiaROM</key> <string>Yes</string> <key>device-properties</key> <string>Copy and paste your string here</string> </dict> </plist> Save your com.apple.Boot.plist, and copy it back to it's original location. Close OSX86Tools. Repair permissions and reboot. Let me know if this works for you. Quote Link to comment Share on other sites More sharing options...
pgb64 Posted March 18, 2011 Share Posted March 18, 2011 Sorry I missed the can not boot to safe mode. If you can read/write your Mac HDD in windows, remove all graphics enablers/injectors. Remove these kexts from S/L/E. NVDANV50Hal.kext, NVDANV40Hal.kext, NVDAResman.kext. Try a boot into OS X with your -x -v flags, post the error if it doesn't boot. Good luck.

toolbox1234 Posted March 18, 2011 Author Share Posted March 18, 2011 Looks like I will return the card to the store. In addition to the 10.6, I also have a 10.5 installation on the same hard drive. Won't do me much good if I don't have a video card that will work for both. Will read more before buying again. Quote Link to comment Share on other sites More sharing options...
toolbox1234 Posted March 18, 2011 Author Share Posted March 18, 2011 Making progress... I borrowed a MSI HD4350 512MB and it works under 10.6.6 by adding device ID to ATI4600Controller.kext. Now if the system has audio and able to sleep, I am all set. For 10.5, I can boot it in safe mode which is a lot better than the GT430.
