Stuck at gray screen with mouse pointer

Post Installation - Stuck at gray screen with mouse pointer

The unibeast installation went well, but I can't actually get into the installed OS.

When the computer first boots, it gets past the apple logo, and hangs at the gray screen with the mouse pointer.

I have tried verbose mode, but it all looks fairly normal, and the computer hangs in the GUI after verbose ends anyway.

If I try -f or -x, Chimera returns "Can't find /System/Library/Kernels/mach_kernel"

It's a P55M-UD2 w/ a Radeon HD6870

Any ideas?

So some new developments...

If I boot the Unibeast USB and choose the drive with my Yosemite installation to try to get into the installer, it boots the Yosemite installation in safe mode. When I try to boot without the USB, I still get the gray screen with mouse pointer.

I have tried both GraphicsEnabler=Yes, GraphicsEnabler=No, and there is no change.

Has anyone else seen this?

Try adding to your boot.plist file:

<key>IGPEnabler</key><string>Yes</string>

I fixed this problem by moving my SMBIOS.plist to the /Extra folder on the flash drive.

So far I've tried combinations of:

GraphicsEnabler
PCIRootUID
dart=0 (although it looks like my bios doesn't even support this)
IGPEnabler (I don't have onboard graphics, so I'm not sure about this one either)
npci=0x2000, npci=0x3000
kext-dev-mode=1

I'm still stuck at the gray screen and can't get into the os without safe mode.

You might need to add screen resolution...

I thought that only adjusted the screen resolution on boot. However, I tried and still not working.

Here is a video of my troubles: https://www.youtube.com/watch?v=Lys1caB3kG0&list=UUH_xjtii-hrHn3tsRi5ozVw

Does anyone see anything obvious?

Did you ever get this fixed? I have the same problem.
