Intel 4600 HD for Mountain Lion?

[fknchino]

Hey all, I've got a fairly 'new' PC and I've successfully installed Yosemite so far with no big issue.

However, I need to install Mountain Lion 10.8.5 for certain software compatibility.
I'm currently stuck on the dreaded IO Bluetooth error / Graphics issue which pops up no matter what bootflag I enter (Clover bootloader).

I'd like to clear things up for myself and others trying to install a slightly older version of OSX on a newer machine.
Is there any possibility for a solution or am I just going in circles!?
I have no experience editing DSDT files and I've yet to manually install any graphics kext.
Would love to hear from anyone that has been through a similar experience.

Cheers thanks

10.8.5 supports HD4600 natively with correct ig-platform-id injection, correct BIOS settings, digital connection to monitor, etc.
