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:
-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?
