OS X 10.8 Mountain Lion bootable USB (without MAC)

Download the raw file from here.

How to use:

1 - Copy the .raw file to an USB stick using SUSE Studio Image Writer.

If you have error during copy, eject and re-connect the pen drive. When Windows asks if you want to format it, cancel and run Image Writer again.

If the problem persists, disable your anti-virus software, it may be blocking raw write to the drive.

Another Image Writer for Windows, if SUSE doesn't work

2 - Boot the USB drive and install.

If you need, type boot options, for example:
-v (verbose boot) [default]
-x (safe)
-s (single user)
GraphicsEnabler=yes (enable graphics card drivers) [default]
USBBusFix=yes (fix problems with USB devices)
npci=0x2000 (use if boot stops at "PCI configuration begin")

If you need, use TransMac to remove kexts which are causing problems (System/Library/Extensions) and use the flag -f (ignore caches) at boot, or remove /System/Library/Caches/

If you get KP related to ApplePolicyControl.kext remove /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/ApplePolicyControl.kext

If boot stops right before reaching the installer, or graphics aren't working right, remove video kexts and boot with GraphicsEnabler=No -f

Intel = AppleIntelHD* AppleIntelSNB*
nVidia = GeForce* NVDA*

You need at least one free partition, use Disk Utility (in the Utilities menu) to erase it as Mac Os Extended (Journaled).

If you want to install Chameleon (the boot loader) in this partition and you use MBR (not GUID, like if you already have Windows in the HD), it must be a primary (not extended/logical) partition.

Wait for the installation to finish and restart.

3 - Boot the USB drive, then choose to boot the HD you just installed OS X (not the installer USB again).

4 - Install Chameleon and the Extra folder to the HD.

I recommend using Chameleon Wizard to install and create/configure org.chameleon.Boot.plist and SMBIOS.plist in /Extra folder. ... pic=257464

5 - Install essential and other kexts you may need (network, audio, etc).

FakeSMC.kext is always needed.

While you don't have power management fixed, you will probably need NullCPUPowerManagement.kext.

If you use PS/2 keyboard or a laptop you will need VoodooPS2Controller.kext (or ApplePS2Controller.kext) and AppleACPIPS2Nub.kext.

I recommend using Kext Wizard to install kexts. ... pic=253395
