Asus X79 Rampage IV Extreme | Core i7-3930k | Radeon HD 7970 Ghz 3GB
6 Cores at 4.2Ghz

Mountain Lion 10.8.4

by MK500 and shilohh

Huge thanks to tonymacx86, MacMan, Hexa, and mitchellk without whom this machine would never have been built.
Special thanks to Shilohh for his DSDT work.

WARNING: This guide will ONLY work fully with the specified motherboard and video card because the included DSDT is injected with specific code to support them. However, you may find several steps useful if you own a AMD 7xxx card and are having trouble with install or boot.

Comments:

The goal of this system is a powerful 6-core with moderate over-clock (for reliability) and similar noise level to a Mac Pro. I'm have a seperate post for over-clock details here.

This machine is extremely quiet (Mac Pro level) and stable. I run 4.2Ghz with idle temperature is under 40C at 24C room temperature. Under moderate load it runs in the 50s. Under Prime95 (for testing) it will run high 60s.

Working: Sleep, Audio, Video (accelerated), USB 2 ports, USB 3 ports, SATA ports, eSATA hotswap ports, Intel Ethernet.

Not working: iStat/Sensors. Must sleep/wake once each boot. Power management (it stays at 4.2Ghz). On-motherboard bluetooth; replaced with cheap bluetooth dongle.

Installation Steps

1) Install BIOS 3602. This is necessary to use included DSDT (BIOS must match DSDT).

http://dlcdnet.asus.com/pub/ASUS/mb/LGA2011/Rampage_IV_Extreme/Rampage-IV-Extreme-ASUS-3602.zip

Photos | BIOS Settings

2) Prepare USB stick using UniBeast 2.0.1 and OS X Mountain Lion 10.8.4 (updated via app store). PLEASE name your USB stick "USB". If you are unfamiliar with UniBeast, follow the steps in "STEP 2: Create a Bootable USB Drive Using UniBeast" here:

tonymacx86 Blog: UniBeast: Install OS X Mountain Lion on Any Supported Intel-based PC

3) Connect your USB thumb drive to the USB port above the white one on the motherboard. Ensure the hard drive you will install to is connected to one of the 6 SATA ports on the Intel bus (NOT the two far left red ASMedia ports). Or use a PCI SSD like mine.


4) Power on your computer and hold F8. Select the USB stick and type the following when the Chimera screen comes up (just start typing and the box will appear):

Code:
-v cpus=1 npci=0x2000 GraphicsEnabler=No
5) Format your hard drive GUID with two partitions. The first large partition should be named "OSX" and standard journaled format (you may rename later). The second partition should be as small as possible and FAT format. Quit Disk Utility. Install the OS as usual. Move your mouse from time to time so your screen doesn't go to sleep.




6) On reboot, hold F8. Select the USB stick again and choose it when Chimera comes up, then type the following (just start typing and the box will appear):

Code:
-v cpus=1 npci=0x2000 GraphicsEnabler=No
7) Open Terminal in the same way you opened Disk Utility above. Run the following two commands:

Code:
mkdir /Volumes/OSX/ati_backup
mv /Volumes/OSX/System/Library/Extensions/ATI7000Controller.kext /Volumes/OSX/ati_backup/
8) Quit Terminal and Restart your computer.

9) On reboot, hold F8. Select the USB stick and when the Chimera screen comes up select your newly installed Mountain Lion disk. Then type the following:

Code:
-v cpus=1 npci=0x2000 GraphicsEnabler=No
10) Go through the normal OS X first time setup steps (user account, etc.).

11) Drop shilohh's DSDT file below onto your desktop. Decompress the zip by double-clicking. You need this for built-in audio, video, USB, and sleep.

Shiloh's DSDT for 7970

12) Install MultiBeast - Mountain Lion 5.3.1 as seen in image below. If you have an SSD that requires TRIM support, then check the appropriate option under TRIM.

MultiBeast Configuration for Mountain Lion

13) Download 898 Audio kext from here, drag kext to desktop. Download VoodooTSCSync kext from here, uncompress and move kext to desktop. Also download SleepEnabler from here, uncompress and move kext to the desktop. Then run the following command in Terminal:

Code:
cp -r /Volumes/OSX/ati_backup/ATI7000Controller.kext ~/Desktop/
Then install using KextBeast as shown below. You do not need to do "rollback" or anything else, as installing this Kext is equivalent to a rollback. The DSDT takes care of the rest.

Kextbeast Installation

14) Download Chameleon Wizard from here to install updated boot0 file (needed to avoid crazy characters at boot). Launch Chameleon Wizard and allow it to update. Make sure your Target Partition at bottom is your new Mountain Lion disk. Click the Boot0hfs bullet. Then just click the Install button.



15) You are ready for your first boot. Go to Apple -> Restart... and hold F8 to select your newly installed drive. You can unplug your Unibeast USB stick now. When the Chimera menu comes up, hit the down arrow on your keyboard to select "Boot Verbose" and hit enter to boot.


16) At the white/black screen after boot completes (HD access stops), put your computer to sleep using the power button. Be patient after hitting power button; it can take up to 2 minutes to go to sleep the first time. Then wake it back up and you should be up and running. You will need to do this at each boot until the ATI 7xxx issue is fixed. Subsequent sleeps (once booted) are quite fast (few seconds), and 2 minutes is worst case at boot. It's often much faster.





FAQ:
Q: If I'm just fixing an existing build; can I add the FAT partition without reformatting my drive?
A: Yes! In Disk Utility, just select your existing drive and click "Partition" on the right. Then click the little + below your Partition graph. Then proceed with the instructions.

Q: Why the heck do I need this little FAT partition?
A: The small FAT partition is needed in combination with the Chameleon Boot0hfs to get around the Boot:(bunch of strange characters here) bug that happens if you have a single AMD 7xxx card installed as primary (and no other video). My guess is Chimera will eventually be updated and this won't be needed any more. It's a very solid workaround for now.

Q: Can I use the new Chimera 2.1.1 now that it has "Added AMD 7xxx graphics card detection"?
A: No, you must switch to Chameleon using the Chameleon Wizard method in the build instructions. The new Chimera does not fix the garbled-text at boot issue. This issue is fixed in my instructions by using the Boot0hfs method and having a small FAT partition. Hopefully this workaround won't be needed forever; but it works well for now.

Q: Can I just select the ALC898 checkbox under Drivers - Audio - Realtek ALC8xxx in MultiBeast install?
A: No. For some reason this does not work with any of my tests. If you follow my instructions you will have fully working audio on first boot without selecting any Audio options in MultiBeast.

Thanks Ritey! I'm a bit of an X79 advocate; so I wanted to prove that you could do a full install with one of the newly supported AMD 7xxx cards. It took me a while to figure it out and test thoroughly -- and then to document. I must have installed OS X like 20 times. But it's a very consistent process now.

This GPU is very fast. And I've had up to 4 displays running simultaneously without problem. I hope the sleep/wake trick becomes un-necessary at some point; and then it will be perfect.

You have done an amazing job! The ATi video IMO is superior to Nvidia for photo editing, which is the main reason I want a good Hackintosh.

The sleep/wake issue should not interfere with having a dual boot system should it?

I've got another SSD on the way because of your success. :D

I put in a 1TB WD black drive and installed Windows 7. I just hold F8 and power up and choose the Windows drive. No problem!

I do recommend you disconnect your Mac drive when you install Windows. I've seen Windows corrupt my Mac boot on multiple occasions. Once installed they live together without problems though. It's just best to keep them on separate drives.

What is the purpose of the extra (small) partition?
