I have successfully completed a fresh install of Mountain Lion using Unibeast 1.5.3 and I think I got everything working with the exception of USB 3.0. Does anybody know if USB 3.0 support will be added for Mountain Lion for the P67A-UD3-B3 board? If not, is there an add on card I can purchase that comes with native drivers for ML?

Thanks

Awesome. Can you please post your MB settings? Are you using bios F9?

Thanks
 
Yes I am using the F9 bios. I'll put together a detailed post listing everything I did from start to finish. So far sleep is working just fine and the OS is stable. USB 3.0 is the only thing I can't seem to figure out.

P67A-UD3-B3 (Rev 1.1) Mountain Lion Success (Step by step guide)

Motherboard = Gigabyte P67A-UD3-B3 (Rev 1.1) F9 Bios
Graphics = Asus HD6870 1GB GDDR5 using two monitors via the display ports. (Not tested using HDMI ports)
8GB Apple Memory (4x2GB dimms) I just happened to have this memory on hand, it is not required) (I also didn't have to pull any out to do the install)
90GB Corsair SATA 3 SSD. (Not very big, but big enough for the install and some testing)
CORE i7-2600K LGA1155 CPU (Unlocked, but I am not overclocking at this time)

I purchased Mountain Lion via the app store and created a bootable USB stick using the Unibeast 1.5.3 process documented on this site.

For those of you who haven't been through a Unibeast process before, it is a hurry up and wait process. The first part goes really fast and then it tells you it will be done in a minute, but really that minute is more like an hour depending on what system you are building it on. Just be patient and don't interrupt it, it will finish eventually. It's well worth the wait. Way easier than the alternative way of doing an install.

Note: In my case the HD6870 Graphics card suffers from an issue where you boot to a white screen and you are able to move the mouse around, but can't do anything else. This problem has been solved and I referenced the link below to fix the issue.

http://www.tonymacx86.com/mountain-...mountain-lion-6xxx-gpu-issues-fix-inside.html

1) Update to the F9 BIOS which you will find on the Gigabyte site.

2) Download the DSDT for your Rev board and BIOS version from this site.

2) Boot from the Unibeast USB stick you just created.

3) I did a bare metal install so I went through the disk utility and partitioned/formatted my SSD.

4) Start the install. (Mine finished in about 9 minutes). The beauty of Unibeast!

5) Boot back up using the Unibeast USB stick and select your newly created Mountain Lion partition on boot.

6) Once up place the DSDT file on your desktop as well as Muiltibeast for Mountain Lion.

7) If you have a Graphics card such as mine, you need to complete the instructions you started above. (It can be done later, but now is a good time)

8) Run Multibeast for Mountain Lion and select the appropriate options. (I have included a screen shot of what I selected)

9) Reboot when prompted and you should be all set.

I added a few low quality pictures, but they should be clear enough for you to see. Keep in mind that this is a best effort and I am not 100% sure of my BIOS settings, but they seem to work for me.

A couple of things I have noticed right off the bat in Mountain Lion is that there is no X server included. If you click on the x-terminal under Utilities it will prompt you to download XQuartz. Looks and works just like the X that use to be included with previous versions os OSX.

I also noticed that you can't just install any old software package like you could in the past. You have to allow it under system prefs first. I included a screen shot of that as well.

Good luck! I hope this is helpful to many of you.

Thanks for taking the time to post. Sleep finally works!
Sorry I can't help with USB 3 as I don't have any 3.0 drives.
The only issue so far is the eject key on the keyboard and the DVD drive itself do not work.
I haven't used my DVD drive in forever so I'm not going to waste any time on it.

I have found that ML by far has been much more painful to install than Lion or SL.
Anyhow, glad I got it running. Thanks so much for posting your BIOS and MS settings.

BTW, no issues so far with 10.8.1

Cheers
 
Since I am still in the testing phase I decided to overclock my CPU. I took it up to 4.2GHZ and it seems to be very stable. I did rerun multibeast to make sure I had the right profile to support the overclock. I encoded a bunch of movies using Handbrake and had all cores pegged for several hours without any issues. I just installed the 10.8.1 update and will continue to test with it, but so far it didn't seem to break anything. My DVD drive is working fine both before and after the update. I only control it from the arrow in the upper right of my screen and that seems to be fine too. My keyboard is not a MAC keyboard so I don't have a good way to test it from there. F12 doesn't seem to do it.
 
After reading your post I just completed my own fresh install on this exact same board, upgrading from F7 bios to the F9 version first. Everything went pretty well and I'm 90% up and running. I have a couple of issues though.

Setup:
P67A-UD3-B3 1.1 F9
Core i5 2500k @ 3.6 GHz
16GB RAM (4 x 4GB DDR3 1333)
EVGA gForce 8800 GTS 512MB
2 x WD 640 GB Caviar Black
2 x Seagate 2TB Green

The biggest issue is that my internal drives are being detected as external with the orange icons. I've tried the IOAHCIBlockStorageInjector.kext, but it didn't help. This seems to be tied to a problem with the internal drives randomly mounting as read-only on boot. Sometimes I'll boot up and they're fine, other times one might be read-only, or all could pop up as read-only. Reboot and sometimes they're fixed, sometimes it takes 2-3 reboots. Anyone else have trouble with this?
 
I'm not sure if this is the fix for your problem, but I will post my latest findings when going through the same install process using a non SSD hard drive. What took me all of about a half an hour to complete the first time through, took me an entire day of messing around and reinstalling when I switched to a Seagate 750GB Momentus Hybrid drive.

I ran into two issues major issues.

1. There is something different about some of the newer drives and I ended up using this thread to fix the issue. Bottom line is that you have to use the Unibeast to boot up until you use the following thread to fix it so it boots from the hard drive.

2. I kept getting an error that said waiting for root device and the system just hung on that step and it repeated it a few times. If I booted up and chose the option to "Ignore Caches" the system would boot just fine. I found the following thread and followed it to resolve the issue.

Hope this fixes your issue.
 
After weeks of trying and no luck, I have the same board, updated the bios to the new UEFI u1a and it installed and ran perfectly with only having to use PCIRootUID=0 for my NVIDIA 470 GTX. Used multibeast and only needed audio to work so I installed the 889 kext and everything runs perfect except for boot camp, which doesn't matter since I can triple boot win7 win8 and OSX ML.

Gigabyte P67A-UD3-B3 rev 1.1 U1A
Intel Core i7 2600K Sandy Bridge
Corsair 16GB DDR3 1333
Crucial 64GB SSD
EVGA GTX 470 SC
 
I had 0 success with your guide, tried twice.

It just hangs at the white screen with grey logo

-v will have it hang aswell

**** off, Snowleopard worked fine on this rig, spent all day trying to get ML running on it
