Mountain Lion on MSI G31TM P21

[Mr. Xtreme]

I got OS X Mountain Lion on the MSI G31TM P21, here's how...

 

Things you will need:

 

A existing Hackintosh/Mac/OS X Virtual Machine,

A 8GB or larger USB stick,

2GB or more of RAM,

Intel Core 2 Duo or greater,

myhack here Download Link

A video card (Integrated Graphics will work),

 

What to do next:

 

Now run myhack, change settings according to your system.

Reboot the system,

press del (short for delete repeatably until you get to the BIOS,

Change the boot order so it boots from your myhack usb disk,

look for "HPET" int the BIOS and enable it.

save and exit,

when you get to the myhack boot (It's chameleon) type "-v USBBusFix=Yes" (with-out the quotes),

When you get to the language screen select your language,

Start disk utility from the utilities drop down,

Format your destination disk with Mac OS Extended (Journaled), name it whatever you want.

In options set the partition map to GIUD,

After it's done quit Disk Utility,

Install OS X; no need to change the default settings,

Reboot.

Again enter the BIOS but now change the boot order to your HD.

Again type "-v USBBusFix=Yes" at the boot prompt,

Set it it up (add needed bootlegs for chameleon, add kexts and other needed stuff

Before reboot install Clover/Chimera*

Download kext Wizard and install the attached kexts,

 

Reboot and enjoy   (I do not own these kexts; I only uploaded them) (VoodooHDA uploaded is for Mountain Lion).

*If you like them instead.

If you have any problems please post here no PMs.

 

EDIT: Made instructions clearer, Changed minimum CPU from "Intel Core 2 Solo to Core 2 Duo to match the "OS X Mountain Lion" requirements, Mentioned that you only need to install a boot loader if you want, Added steps to change boot device to the hackintoshed HD, removed mentions of using the usb as the bootloader.

EDIT2 @12/6/15 Made the tut even clearer.
