Install Mountain Lion 10.8.5 on Haswell ASRock Z87E-ITX Hackintosh

since Haswell CPU is now natively supported by Mountain LION 10.8.5 it is very easy to

All you need for that is a legal copy of Mountain Lion 10.8.5 from the App Store, the patched BIOS for your Asrock Z87E-ITX Mainboard, Unibeast 2.1 and USB Stick with 8GB space.

Prerequisites:

Asrock Z87E-ITX Mainboard

I used for my project energy efficiency 35 Watt CPU: Intel i5-4570T

My whole system is consuming only 22 Watts at mid range load in that combo!

Unibeast 2.1

PMPatched Z87E-ITX Bios

8GB USB Stick

Optional like my Low Wattage Setup:

First of all we need to prepare our Mainboard with compatible BIOS which we can download here

Download and extract the content of the zip file to your USB Stick and plug it in your PC.

On boot up hit F6 and flash the shown Bios Update.

Now its time to prepare the Mountain Lion Installer USB Stick:

Insert your USB Stick to you Mac again and open the Disk Utility application.

Click on the USB Drive on the left pane then on the partiton tab to the right.

Choose:

Partition Layout: 1 Partition

Click Options choose: Master Boot Record

Format: Mac OS Extended (journaled)

then: Apply

Eject your USB Stick and reattach it to your Mac

Download Unibeast 2.1 from here and run it.

Choose your USB Stick as Destination and Choose Mac App Store Mountain Lion 10.8

Click continue and enter your password.

Now it will take some time to complete the preparation process.

Eject the stick after the process has completed and plug it in your PC.

Hit F11 on system powerup and boot your USB Stick.

After some time the Mac OS Installation screen will appear.

Before you can install Mountain Lion on your PC you have to prepare your Target disk first.

Goto Disk utility on the upper tab and follow the steps again as shown above again but choose your target hdd but select GUID partition scheme under options instead of Master Boot Record.

Apply then start the installation process and Choose your new partitioned HDD as target.

After the system have completed the install process it will reboot.

The important part now is to boot your System into safe mode with boot flags: -x because else it will hang on Apple loading screen. So at the boot loader prompt choose your hdd and just enter: – following x and hit enter.

After we have successfully booted up into Mountain Lion we finally have to download and install latest Multibeast 5.5 and install chimera 2.2 from there so booting from hdd without your attached prepared usb stick is possible, kext utility and add drivers for our new platform.

Recommended Multibeast 5.5.3 Packages:

UserDSDT/DSDT-Free Installation

Drivers & Bootloaders > Bootloaders > Chimera v2.2.1 r2248

Drivers > Network > Intel hnak’s AppleIntelE1000e

Drivers > Misc > FakeSMC & FakeSMC Plugins

Customization > Generate CPU States

Customization > Use KernelCache

For Audio/WLAN/Bluetooth:

HDAEnabler1.kext, audio_ALC1150 and audio_hdmi_8series from github by toleda Not necessary anymore since ALC1150 kext now included in newest Multibeast release 5.5.3

Not necessary anymore since ALC1150 kext now included in newest Multibeast release 5.5.3 Bluetooth/Wifi: get the latest from osx86.net

If something went wrong after installing kext files and/or misconfigured Multibeast and System hanging in a boot loop,

i recommend you to plug your USB Stick again to your System and boot from the old bootloader with boot flag -x to get back into safe mode.
