How to create bootable Mountain Lion 10.8.2 USB installer using myHack


MyHack is quite popular hackintosh installation tool, functionality is more less the same as tonymacx86’s Unibeast + Multibeast installation method. This method is fairly simple and straightforward, no terminal or coding required, just use this simple tool graphical interface to create your own bootable USB installer.

You will need:
– Install OS X Mountain from the app store or the InstallESD.dmg from it.
– An External Hard Drive or USB Flash Drive with min. 8GB of space.
myHack (I used version 3.1.2 for this tutorial)
– Working OS X 10.6 or newer to prepare your installation device (this can be a real mac, a hackintosh, or windows with OS X virtual machine).

OK, so first plug your USB drive to working Os X 10.6 or later, open Disk Utility from /Applications/Utilities and select your USB Disk from the left menu. Click “Partition” in the upper menu, select “1 Partition”, Name it the way you want, in my case “osx install”, under Format select “Mac OS Extended (Journaled)”. Click Options and select “GUID Partition Table”. At the end click Apply and Partition and wait until finish. Close disk utility.

Now open myHack, enter your password, select “Create OS X Installer”, than select “Create OS X 10.8 Install Disk”, as a target select your USB drive (“osx install”). When “myHack needs the location of the installation source” appears click “Browse Manually”, browse to your InstalESD.dmg file, select it and click “Open”. Wait for a while and when “Ready to copy installation data to target” appears just click “Ok” to continue. Wait for a while, be patient until “myHack finished” message.

Now your bootable USB Installer is ready to use, or modify if needed.

myHack will automatically remove ApplePolicyControl.kext, AppleTyMCEDriver.kext and AppleUpstreamUserClient.kext from /System/Library/Extensions folder on USB drive. Also GraphicsEnabler=Yes flag will be added to /Extra/org.chameleon.Boot.plist file on USB drive. Edit org.chameleon.Boot.plist to suite your needs.
