Looking at everything I can find in these forums I have managed to install my GeForce 9800 GT using EFI and it is correctly recognized and I can use all display resolutions. The one thing I cannot get to work is Quartz Extreme. Under System profiler it says Unsupported. Is there an extra step I am missing to get it to work, or is it simply not supported?

Here is my bootlist in case that helps at all.

Thanks for your help in advance!

some times efi strings are not enough

download nvidia 9series driver http://forum.insanelymac.com/index.php?showtopic=132089

and install it then repair premissions and reboot then when you boot back up if you dont have qe supported then remove the efi strings

I'm having the same problem, i've installed the drivers, how do I repair the premissions and last resort how to remove efi strings?

Thanks for your help

Now I just have a blue screen without the cursor after the apple screen with the round loading ring. Help ? Desktop only appears with booting -x (safe mode)

I´ve tried tons of methods..nothing seems to work. Has anyone experienced the same problem using EFI string and Nvidia drivers?

This one's easy, I hope!

Download osx86tools from http://code.google.com/p/osx86tools/

I don't have it right now on my Snow Leopard install so I can't remember where the option is exactly, but you should find a button that says 'enable quartz extreme' or 'enable opengl' - both mean the same thing. Reboot and you should have QE!!

Just got my PNY 9600GT working tonight, using the 9000 series drivers. OSX86 tools turned on OpenGL but wouldn't get QE working, but by following Aquamac's guide

http://aquamac.proboards.com/index.cgi?act...&thread=509

I finally got QE turned on in about five minutes flat.

I have a 9600 GT with DVI and HDMI outputs, and I have similar problem before. I managed to find out that if you get a blue screen without the cursor, it simply means you have the screen output to the other head instead of the current one you connected to. For me I use the DVI port to a LCD monitor but for some reason the card alwasy use HDMI port as primary display after boot up, even though I didn't connect anything to the HDMI port. I didn't find a thorough fix yet but the workaround is quite easy, just turn the monitor off for several seconds and turn it on again, it seems will trigger the driver to re-detect the port and will switch back to use the DVI port as output.

Hope this will help your 9800, you can even verify it by connect to the other display port on your card to see if it has anything on it.

Huh, after two days of installing the drivers and repairing permissions and deleting files in a million different methods I just connected the display to the other port and it works ! But still no QE, OpenGL is supported tho. Thank you!
