Thanks guys! Especially at post #5 solved my problem. This is the detailed solution for my ML-upgrade on motherboard ASUS P8 Z68-V/GEN3
My Hackintosh upgrade from OS X Lion 10.7.4 to OS X Mountain Lion 10.8.2
Motherboard: ASUS P8 Z68-V/GEN3
Graphics: Nvidia GeForce GTS 450 1024 MB (changed to ASUS nVidia GeForce GTX 660 Ti)
Processor: 3,41 GHz Intel Core i7
16 GB 1333 MHz DDR3
I first tried using the above graphics card but that did not work at all. So I upgraded to
ASUS nVidia GeForce GTX 660 Ti and then things started to work out.
I followed this procedure:
1. I bought and downloaded Mountain Lion 10.8.2 from Appstore and made the
USB-stick for installation using Unibeast.
2. To reach the installer I used the bootflag –x
3. Restart after installation
4. I used –x bootflag again to be able to start Mountain Lion
5. After logging in to Mountain LIon, I ran Multibeast clicking these features:
Since the MBO has no DSDT-file: Easybeast Installation
For sound: Realtek ALC8xx/without DSDT/ALC892.
Network: hnak’s AppleIntelE1000e Ethernet
Customization: Bootoptions/GraphicsEnabler=0
So far so good, but after I tried to restart, it stopped at the famous and enjoyable forever spinning wheel. Sounds familiar? But I found a solution on this link.

Thanks guys! ☺
In short this is how to stop the forever spinning wheel:
1. In post #5 You’ll find a file called AppleACPIPlatform.kext.zip
2. Download the file and place it on Your desktop
3. Install the kextfile using Kexbeast (from tonymac)
4. Then run Multibeast for Lion (Yes Lion!!) and only click ”Repair Permissions” under System Utilities and install.
After that, reboot and Mountain Lion should start in normal mode. At least it works for me. I hope it also will work for You.
Regrettably I’m still using Lion 10.7.4 since my monitor hardware calibration software cannot communicate with monitor NEC LCD 2690WUXi2 due to changes made in Mountain Lion by Apple. NEC is warning users from upgrading to ML until the problem is solved. So I just have to wait for Apple’s next ML upgrade and hope for a solution. But that’s another story. Now I at least have a separate ML disk working.
