Installation of Retail OS X 10.8.2 Mountain Lion on Gigabyte GA P41T-D3P + update to 10.8.3

Updated to Mountain Lion 10.8.3 without any significant problems. Check bottom of the post for detailed info!

Gigabyte GA P41T-D3P is very cheap motherboard and it’s perfect solution if you wanna use your older socket 775 CPU with a newer DDR3 memory to build a low budget hackintosh. Actually its cheaper to buy new motherboard + 2x4GB DDR3 memory modules than just 2x4GB DDR2 memory modules which are very expensive this days. This tutorial will show you how to setup your BIOS, and install OS X 10.8.2 Mountain Lion on this specific motherboard, but it should work for most intel based Gigabyte main boards and core2duo or later processors. You just need to find exact hardware you use, and than select specific drivers and (if u use) DSDT.aml for your main board.

GA P41T-D3P rev 1.5 Bios FD, Intel G41 chipset, ICH7 (check osx86 project for compatible hardware)
On board LAN Realtek GbE LAN chip Realtek RTL8111E
On board Audio Realtek HD audio codec ALC889
Zotac NVIDIA GTX 560 1024 MB GDDR5
Kingmax 2x4GB DDR3 1333MHz RAM
Logitech USB keyboard and mouse.

Files you will need:
– OS X Mountain Lion 10.8.2 from app store, or try search torrents if u wanna test if your system is capable to run OS X. OS X Mountain Lion costs only 20$, so please buy it…

ShowHiddenFiles app (to show hidden files)
– GA P41T-D3P rev 1.5 Bios FD DSDT.aml file
Kext Utility

Also you will need USB drive (8 GB or larger)

This tutorial is for educational purposes only. You, of course, assume all responsibility for choosing to follow this tutorial. Also, OS X EULA states that you can run Lion on Apple labeled hardware only.

First step is to create bootable USB drive.

To create bootable USB drive I used Unibeast method, whole process is described in this tutorial.
Otherwise there are alternative bootloader installers as myHack or Kakewalk. For myHack method  you can follow this tutorial.

Setting up the BIOS and installing system.

Ok, so once you created your bootable USB install drive, plug it into your computer and enter the BIOS settinfs (Press Del key on boot for Gigabyte motherboards). This step is going to be different depending on what motherboard you have but it’s fairly straightforward.

First find boot options and select USB hard drive as your first boot device.

There is no AHCI settings On GA P41T-D3P main board (ICH7 chipset doesn’t support AHCI), so  you are not going to be able to enable Trim Support for any SSD drive. Anyway it’s possible to install ML without AHCI. Turn on your computer, press delete to load bios, choose “LOAD OPTIMIZED DEFAULTS” and than change your settings like on pics bellow.

Press F10 to save your changes and boot your PC with UniBeast USB drive. When UniBeast starts, select USB and press enter. If you have issues try again but this time type GraphicsEnabler=No in the prompt. If you’re still having problems try booting with the -v flag and noting what error you get.

Once it boots you should see the OS X installer. We’re most of the way there however there’s one more thing to do before installing. Come up to the top menu and select Disk Utility. Here you should see all hard drives connecting to your computer. Pick the one you want to install Mountain Lion on and select the Partition tab. In options select GUID Partition Table then choose Mac OS Extended Journaled as the format and name it HDD. Then click Apply.

Close Disk Utility and go through the installer like normal. When it comes to the install screen just pick the Mountain Lion disk and then click install. This will take quite a while so be patient and let it do its thing. Reboot after installation finish back into the UniBeast USB drive. This time select HDD to boot from, and then continue installation.

Creating bootable OS X 10.8.2 system

First you will need to allow running apps downloaded from other source than apple store. To do this go to System Preferences / Security and Privacy and unlock the preferences. Under “Allow applications downloaded from” select “Anywhere” and close preferences.

If you want or need to extract your own DSDT.aml follow this tutorial.

For GA P41T-D3P  I used this DSDT.aml file, unzip and put DSDT.aml on your desktop and than start MultiBeast. Again go through the installer until you reach the options.
Under options you choose UserDSDT or DSDT-Free Installation.
Next click arrows to open Drivers and Bootloaders / Drivers / Audio / Realtek ALC8xx / With DSDT  and than select ALC889.
Under Network select Lnx2Mac’s RealtekRTL81xx Ethernet v0.0.90, and finally  under Bootloaders check Chimera v1.11.1 r1394. Continue and finish the installation.

Unmount and unplug your USB Installer, and reboot your hackintosh, and now you can install your graphics.

Zotac NVIDIA GTX 560 works OOB, so you dont need to do anything ( multibeast puts GraphicsEnabler=Yes automatically to boot.plist file ). If you plan to use your hackintosh for video editing install Nvidia Cuda Drivers for Mac From

And now you are good to go, everything should be fully operational, graphics, sleep, audio, network…  works practically out of the box 🙂 enjoy your new Hackintosh :) !

UPDATE: I updated system to ML 10.8.3 with default App Store Software Update without any significant problems. Only thing need to be fixed is Audio Device (Realtek HD ALC889), so before update backup your /S/L/E/AppleHDA.kext, and after update put it back to /S/L/E/, run Kext Utility and reboot. Now, your system should be updated to the latest 10.8.3 Mountain Lion release.
