Hi, I've had my system running absolutely fine with Snow Leopard, however time had come to update. I've followed the process up until the multbeast stage, where I installed No DSDT and only the USB3.0.

I'm Using a GTX580 3gb GPU, 16GB Ram, i7 Sandybridge processor, a 60gb ssd for my main drive and two raid arrays.

The only way that I can boot into Yosemite is by using these commands:

GraphicsEnabler=Yes PCIRootUID=1 Mode=1600x1200x32

Without the commands, the apple screen hangs and then my monitor goes to sleep.

I have added to my chameleon boot plist:

<key>Kernel Flags</key>
<string>nvda_drv=1</string>


This seems to be a graphics issue, so I have installed the Nvidia drivers, not sure if they doing anything to help the problem or make it worse.

Geekbench Scores are identical to the Mavericks install (2600 single, 10484 multi, 32bit), so the system doesn't appear to be limping

Thanks,
Ross
 
So where exactly the problem is?
