Hello everyone,

I followed direction on installing Mountain Lion with unibeast 1.5.1 Mountain lion. USB stick boots fine it gets to Apple logo with spinning wheel and after about 1 min or so monitor just turns off like there is no signal. Please advise me on what to do?

I changed mobo settings to AHCI
And installing OSX on separate hard drive.

my system:

Asus p6t motherboard
7i
12 GB Ram
GTX 260 Video card

Thank you

Stan

Did you use a computer with Snow Leopard to create the USB boot?

Its a graphics card issue, there are fixes listed here:

I had a similar problem with a GTS250 - Removing my HDMI to DVI connector fixed the problems.

I've got the same problem and I tried GraphicsEnabler=No but that didn't help
any other suggestions?

I have a msi Nvidia gtx 550 ti

I too am currently having this issue, any luck thus far, I've done a clean install of osx mountain lion I used -v npci=0x2000 to get pass the pic configuration hang. After installing easy beast through multibeast my display shuts off after the apple logo disappears. I know it's logged in I can hit keys and hear them respond. It's a rather vexing situation.

I've the same issues like you described, but only after a BIOS update...
Have you found a solution yet?

thx bru3

(BIOS update X79-UD5 F13p - beta)

Anyone have any luck with this?
I had my Hack running fine then all of a sudden it doesnt output a signal to my monitor.
I did upgrade drivers on my Win7 partition but I dont think that would be the problem.

In my case I solved the problem.
It was an old DSDT file on a other partition.

If you're not using a DSDT. Check your flags for example npci=0x3000 PCIRootUID=0 darkwake=0 GraphicsEnabler=Yes....
