Enable Quartz Extreme on 7600GT

QE

Thanks for the quick response, nfoav8or. I am clueless re: EFI strings. Would you happen to have a link to a good starting point/introduction? Also, a PM with the Zephyroth link would be great!

mising file

Hey, that worked! Thanks both of you for helping. lanceomni, I used your instructions, but there doesn't seem to be a Extensions.kextcache in the Library directory. Is that anything I should worry about?

Flags

I'll look again. I forgot to restart using the flags, but I'll do that, too. But Quartz Extreme is enabled now, so I'm happy!

I'd advise going to EFI strings for great CI/QE support (with help from a .bundle)... otherwise, check your permissions because those installers don't always finish this correctly. then reboot and recheck your graphics... 0.2.1 should work fine for it...

There's always the Zephyroth NVidia Universal Installer... I can PM you a link if you want. This incorporates NVinject 0.2.1 as well.

If your still having issues with NVinject you can try NVkush. Its in my signature. Though Nfoav8or is right its probably a issue with permissions.

You can manually install the kexts.

1. Removed all video related kexts (nvkush, nvinject...)
2. Copy NVinject.kext to /System/Library/Extensions
3. In Terminal write:

sudo chmod -R 755 /System/LibraryExtensions/NVinject.kext

4. Copied NVinject.kext to /System/Library/Extensions
5. Entered your admin password when prompted
6. In Terminal write:

sudo chown -R root:wheel /System/Library/Extensions/NVinject.kext
sudo rm -R /System/Library/Extensions.kextcache
sudo rm -R /System/Library/Extensions.mkext

7. Restarted using the boot flags:

-v -f -F

-v Verbose
-f Ignore extensions cache
-F Ignore com.apple.boot.plist settings

If use any other boot flags add them to number 7.

I have the same series of card as you do (not sure who manufactured yours). Ive used both NVinject & NVkush and both worked equally as well.

Did I miss anything guy?

System/Library/ not Library/ correct?

Im not sure maybe its already been removed. I believe that if you boot with the flags I described it should refresh those two files. I always thought removing those files and using -f would do pretty much the same thing but its just a fail safe. I could be wrong. Have you restarted after this? and used the flags?

Great… now backup

In addition to a full backup I always keep a set of all kexts Ive installed on a USB thumb drive for easy access.

By the way you wouldnt happen to know who the manufacturer is for your graphics card? (PNY, ASUS, EVGA, MSI, Gigabyte...)

Quartz Extreme on an NVIDIA GeForce 9800 GTX DDL

All:
I know this is a very old thread. I have a couple of questions. I installed NVKush using Diabolik's nvkushinstaller.pkg. I also rebooted using -v -f -F. I still don't have the ability to enable Quartz extreme. Am I supposed to re-run permissions? Is Quartz extreme display dependent? I am using an HD monitor connected to my hack.
Any help is greatly appreciated. Flames -->null.
