However, things didn't go very well. I think I need help. I don't know if Aquamac or anyone can help me to make my Quadro 4000 work with GFX string. If I can not get it work , I probably need to return it back to store before the end of this month.
Try dropping these 2 files into your "Extra" folder (see screen shot enclosed). You will have to delete ATY INIT or any other Natit, NVInject type kexts from your System/Library/Extensions folder or Extra folder as these will overwrite the strings. Also you will not want any NVEnalbler instructions in your com.apple.boot.plist. You may of course get a black screen at boot as this may be the first time your card has really been activated. Can you also try the DVI port.
