*** I have written this guide while at work, so I will add the necessary attachments, files, and some screenshots this evening. I'm sure the exact names of some the files and the methods of which to navigate to them may be slightly off as this has been written strictly from memory.
A few notes before we get started.
-Currently running onboard DVI at 1024 x 768 (discrete GPU hasn't arrived yet).
-USB 3.0 seems to work as it is listed properly in "System Profiler" (no USB 3.0 peripherals to test with)
-FireWire, same as above
-Please PM me if you have any successes that aren't listed in this guide so that it can be updated (credit will be noted, of course).
1) BIOS
-Set to AHCI
-Set HPET to Enabled 64-bit
-Set boot priority to CD/DVD first and HDD second
-(Optional) up multiplier to 40x for a 4.0 GHz overclock
2) iBoot 3.0.4
-Boot with iBoot and eject after it loads
-Pop in your retail 10.6.3 Snow Leopard install disc
-Wait about 5 seconds and press F5
-Use the arrow key to select the OS X install disc if it is not automatically selected
-Type in "-v" and press "enter"
3) Installation
-Once the installer opens, go to "Utilities" and select "Disk Utility"
-Partition your hard drive as needed
-Select the partition you wish to use for Snow Leopard and proceed with install
4) Initial boot after install
-After install completes the computer will reboot. You will want to remove the retail install disc and replace it with iBoot.
-Use the arrow to select the newly installed Snow Leopard partition
-Type in "-v" and press "enter"
5) Post install configuration
-Copy the "Post Installation" folder to your desktop
-Double click on the "Z68 Auto Patcher", select you motherboard ("Gigabyte Z68" and then "GA-Z68X-UD3H-B3"), and then click "Patch"
-You should now have a file named "dsdt.aml" on your desktop
-Next, run the 10.6.7 OS X software update, do not restart
-Before restarting, open "MultiBeast"
-The application will automatically close after you make it through the initial prompts and rolling your mouse arrow over the "Continue" button. Go ahead and get this out of the way and "Ignore" the installer error message.
-Open Multibeast again and go through the initial prompts. You will want to select the following:
-"User DSDT"
-"System Utilities"
-Expand "Drivers and Bootloaders" and expand "Kexts and Enablers". Expand "Audio" and expand "Realtek ALC8xx" and select "ALC8xxHDA". You will then want to expand "Non-DSDT HDAEnabler" and select "ALC889"
-Expand "Disk" and select "IOAHCIBlockStorageInjector"
-Expand "Miscellaneous" and select "USB 3.0 - NEC/Renesas"
-Expand "Network" and select "Realtek Gigabit Ethernet 2.0.6"
-Expand "Customization" and also "Boot Options". Select "64-bit Apple Boot Screen" and "Instant Menu"
-Expand "OSx86 Software" and select "Kext Utility B7"
-Finally, select "Continue" and install to your Snow Leopard partition. Once again, do not restart.
-Go back to "Post Installation" folder and open "BridgeHelper". Follow the prompts and install to the Snow Leopard partition.
-Remove iBoot from CD/DVD drive and reboot.
6) Optional Post Install from the "Early 2011 iMac 10.6.7" software update
-Drag the 3 kexts from the "Early 2011 iMac 10.6.7" folder and drop them in "Kext Utility B7" (you may have to open a Finder window and navigate to "Applications" instead of trying to drop them in the expandable Applications folder on the desktop).
-Enter your password and continue the install. Do not reboot.
-Copy "mach_kernel_SB" and paste in the root folder (it will be in Finder at the top left hand side and named whatever you named your Snow Leopard partition). You may be prompted to "Authenticate", enter your password when prompted to continue.
-Navigate to the root folder and open up the "Extra" folder. Double click the "com.Apple.bootlist" file and change the string that says "mach_kernel" to "mach_kernel_SB". This allows your system to boot up with the new iMac SB kernel.
-Open up MultiBeast and select only the "System Utilities". This is a way to repair permissions to allow the previous changes to function.
-Reboot.
7) Conclusion
-You should now have a fully functioning system that is able to be booted from the hard drive. Please keep in mind that I have not fully tested every feature of Snow Leopard or this board. Everything that is used by me on a day to day basis is functioning perfectly. If you can verify that something may or may not be working, please PM me and I will update the thread and we can seek resolution.
8) Possible issues
-The only issue I had after completing the steps in this guide was that Safari would freeze and crash after loading a few pages. The remedy for this is to go to the Adobe site (ironic since Safari may not stay open long enough to get you there
) and download the Flash uninstaller package. Run the package and reboot. Once you reboot you can re-install Flash and Safari should be working normally. I opted to switch to Chrome.
If your audio dies with the 10.6.8 update, install the "AppleHDA.kext" located in the "Post Installation". This is the original kext found in the 10.6.7 combo update.
