Smile How to Install OSX Mountain Lion on PC

How Install OSX Mountain Lion 10.8 on PC

What we need:
a) an Intel Core2 Duo/i3/i5/i7 computer ( mine Optiplex 760)
b) an USB pen (8 Gb is fine )
c) an Hackintosh running Mac Os X to create MLion.dmg and USB Pen.

Start Mac Os X Leo /Snow Leo/Lion (what you like ..)

0. Create OSX MLion DMG for Hackintosh
a. Download OSX 10.8 MLion GM/RTM/Retail (12A269 )
b. find InstallESD.dmg -> "Install Mac Os X"
Open and mount InstallESD.dmg
Show HiddenFiles -> here
Find BaseSystem.dmg inside InstallESD.dmg
Mount BaseSystem.dmg
c. Using Disk utility create an new immage.dmg 8.0 Gb read and write , rename like MLion.dmg
d. Using Disk utility restore BaseSystem.dmg on new image MLion.dmg
e. mount MLion.dmg and rename volume like OSX MLION
Delete packages link inside /System/installation
Copy Packages folder from InstallESD.dmg to MLion.dmg inside /System/Installation/ folder
f. Copy needed Kexts on MLion.dmg inside /System/Library/Extentions
* nullCPUPowermanagenent.kext
* ElliotForceLegacyRTC.kext -> this only if you experience Bios reset
Used Kexts -> here

Copy Mach_Kernel from InstallESD.dmg to MLion.dmg
Copy OSinstall.mpkg patched for MBR inside /System/Installation/Packages
Copy OSinstall. patched for MBR inside /System/Library/PrivateFrameworks/Install.framework/Frameworks/OSinstall.framwork/Versions/A folder
OSinstall MBR Patched -> here

g. Install Extra_Lion.pkg on MLion.dmg -> here
h. Install Chameleon-2.1svn-r1820.pkg on MLion.dmg -> here
Create a folder Postinstallation on MLion.dmg and copy Chameleon-2.1svn-r1820.pkg , Extra.pkg and the three kexts
i. With Disk Utility repair permission on MLion.dmg

1. Create Bootable USB pen with OSX MLion
a. With Disk Utility erase USB pen
GUID + HFS+ journaled
rename it "OSX MLion Boot"
b. With Disk Utility restore MLion.dmg to USB Pen

c. install Extra_Lion.pkg to USB Pen
d. Install Chameleon-2.1svn-r1820.pkg to USB Pen

2. Boot USB pen with OSX MLion and install
switch off PC
a) Boot newly created USB Pen
With Disk Utility Create a HFS+ journaled partition, rename it "OSX MLion"
( You can Install MLion on MBR or GUID partition)
(if you install over a previous OSX [SL 10.6.6-10.6.8 or Lion 10.7.x] , don't create a new partition and you will be able to upgrade your S.O. without loosing anything)
b) Boot again with USB pen and choose to boot HD
