Enable Quartz Extreme on 7600GT

Kip McSkipster · #1 12-17-2008, 03:09 AM

Trying to enable Quartz Extreme on my setup. Here are my specs:

Phenom 9550
Gigabyte GA-MA78GM-S2HP
4GB RAM
Geforce 7600GT

Got OS X running using LawlessPPC 10.5.4. I went through a rigmarole to get the Geforce extensions running - not sure if there was an easier way - but I can change my screen resolution. If it helps, I used NVinject 0.2.1.

Again, would appreciate any suggestions on how to enable Quartz Extreme as I would like to install Final Cut.

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.

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!

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:

Code:

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:

Code:

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:

Code:

-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?

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?

lanceomni · #6 12-17-2008, 03:25 PM

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?

Kip McSkipster · #7 12-17-2008, 04:52 PM

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!

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...)

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.
