I started with a Snow Leopard Hackintosh Setup with the ff:


Almost the same setup from Lifehacker.


Followed the bios correctly


To make it short it was a successful install.

Recently i decided to try out Mountain Lion Hackintosh install and followed this


Problem is after booting into the USB i only reached the part where i can boot from the USB and after selecting my installation i am getting the apple logo and a few seconds a black screen.

Tried reading and used the following boot flag commands like 
But did not get a different result.
Still apple logo and black screen will follow.

How Do i fix this one since i am done with snow leopard and time to move on.
Thank you!

After applying the following commands


GraphicsEnabler=Yes PCIRootUID=1 -v -f -x 


This is what i got. Please download screenshot.




Thank you for assisting. Hope the screenshot is readable enough.



Here's another try 


Commands used:

GraphicsEnabler=Yes PCIRootUID=1 -v -f -x  -s

(in the end i put -s for single user mode)


See screenshot for results:

When I installed Snow Leopard, mine wouldn't start unless I booted with "busratio=30" 


I recommend trying that and also try "cpus=1" and my 10.6.8 would not boot unless I had "USBBusFix=yes" 


Mind you, I have an AMD Processor.

I am having trouble installing Mountain Lion but will give that a try. Thanks!

I did try Iatkos a couple of times. 

Followed the USB boot but it freezes during boot.

Tried the DVD boot and i reached the apple logo then black screen.

No luck. Only the snow leopard version 10.6 worked on my system. If i upgrade to the combo 10.6.8 i get kernel panic after rebooting. Even [url="http://www.insanelymac.com/forum/topic/279450-why-insanelymac-does-not-support-tonymacx86/"]#####[/url] didn't solve the problem.  :(

I always use iAtkos...

they pre-hack it to make it easier to boot.

If you want mountain lion, use iAtkos ML2
