Hi, I have been building computers for years and this is my first mac attempt. I have the GA-Z77X-UP5-TH. I am installing snow-leopard and all is well. I had to take the I3 out of my kids computer to make this work which is a sandy bridge. I then go for update after update helper, all goes well then I reboot and I get a white screen spin ant then black. I says something about error with Itunes. Some other errors, I tried all the boot tricks but nothing made it get past that screen. My hope is to install mountain lion and uni-beast I just cant get there because I need that apple program.. It says I should barrow someones computer but i do not have anyone with them. Do I have an old bios on my new board. I know you don't have enough info but I thought maybe you had the same problems once. Maybe one of my settings are wrong in bios but I have all the recommended settings. Can you help?

as you have replace you Ivy Bridge w a SAndy Bridge this improves your chances -
And as your MB states it does support both IB and Sb cpu's.
What you will need is to do some seachs on this MB - Google and a SB cpu
most of the time we us a DSDT file but this board has an UEFi bios and this can confuse us and the installers.
A DSDT aml file was done by another user - see this link

You will need to create a account /user ID they are not sync'd. DSDT file is in bottom of first post - word of caution many users have this MB anc have had issues w Audio. In SL
You will need to tools that we use and a legal OSX Snow Leopard DVD.
If you set you BIOS into legacy mode and set AHCI and HPET as well as S3 properties as it spec'd in TonyMacx86 Guide
then you can begin -
If now DSDT file - use the non DSDT method in multibeast -
Also follow this guide for a Sandy Bridge CPU

How to do a sandybridge cpu w compatable hardware OSX hack 10.6.8 build. jester969
Typical installation steps are:
1) iBoot + Disk Utility + install Snow Leopard DVD (perform install via DVD) reboot
2) iBoot + Installed OSX HDD (boot with iBoot and loading OS via newly installed HDD) - get welcome screen
3) Run Update Helper and Reboot?
4) iBoot + Installed OSX HDD, run combo update 10.6.8 , DO NOT reboot
5) Run Multibeast and select option which are required to your board.
6) Reboot w/out iBoot
Audio/Ethernet/DSDT
DSDT and BIOS firmware must match to the corresponding number.

You will need a lot of command switchs at start - "-x -v -f acpi=off PCIRootUID=0 GraphicsEnabler=No "
once you have it running suggest you use this setting for each reboot "-v -f PCIRootUID=0"
