[Success] 10.8.2 on Asus P6X58D-E with GeForce GTX 570

[Guide] 10.8.3 on Asus P6X58D-E with GeForce GTX 570

Updated for Multibeast 5.2.1 and OS X 10.8.3.



First, go into the BIOS setup and make sure ACPI2.0 and APIC are enabled. Make sure both the Intel and Marvell SATA controllers are in AHCI mode. And make sure suspend mode is set to "S3 only".

Then create the installation USB drive using UniBeast and the 10.8.3 version of Install OS X Mountain Lion.app. Before using the drive, edit the file "Extra/org.chameleon.Boot.plist" located in the drive that was just created, locate "Kernel Flags" and remove the words "PCIRootUID=1" in the next line, as we'll actually need PCIRootUID=0 for the P6X58D-E, which is the default.

After installing OS X 10.8.3 using UniBeast, place the DSDT file for the motherboard on the desktop (I have included a working DSDT.aml for the P6X58D-E in the attached archive.) Then use MultiBeast 5.2.1 to install the following checked options:



In addition, you'll need a kext for the Marvell Yukon 88E8056 Ethernet adapter which is not found in Multibeast. I have included a copy of this kext in the attached archive.

If you are using a GeForce GTX 570 like I am, you can also add the NVDAGF100AGPM kext in the attached archive to enable power management for your GPU. If you are using a different NVIDIA GPU you can still use the kext but you'll have to modify the model number in the Info.plist file.

Finally, if you would like to have a BIOS splash image that looks similar to those on Macs, I have included an image in the attached archive that you can use to replace the default ASUS BIOS splash image. You'll need the ASUS Update program, available for download from ASUS, to do this. This program only runs on Windows. This image is meant for 16x9 screens. It'll look stretched on 4x3 or 8x5 screens.

what patches did you use for the DSDT?

I used the Asus P6X58D-E motherboard patch and ALC889 patch from olarila.com against a DSDT extracted from my motherboard.

Seems like there's a bug in the MultiBeast 5.0.2 installer, when you use it to install the AppleACPIPlatform rollback, it deletes the original but doesn't actually put back the new one. I've modified the instructions and included the AppleACPIPlatform in the attached file so people can manually replace that kext until MultiBeast fixes this.

Solarein - I have a system that seems to be fully functional, but when I updated from 10.8 to 10.8.2 I know have a very small and intermittent delay. For example, when I move the mouse, it will freeze in the screen for a second and if there is video playing it will pause as well. Also, when switching between apps using Apple-Tab there is sometimes a short 1 sec delay. Any of this happening to you?

Sorry, I haven't experienced anything like that.

Hi there,

I have the Asus P6X58D Premium (non-E) with a GeForce GT 240 video card.

Couple of questions:

1. Will the DSDT that you provided work with my motherboard?
2. Does the BIOS revision matter? Which version are you using?
3. Where can I find the kext file for my video card?
4. Is it safe to use UniBeast to do the Mountain Lion installation?

There are several differences between the P6X58D-E and the P6X58D Premium, so I wouldn't advise using my DSDT for the Premium. I'm using version 0803 of the BIOS for P6X58D-E, and the DSDT I extracted from it appears identical to an earlier one I extracted from my system running version 0701 of the BIOS. But again I wouldn't advise that you use my DSDT with your motherboard since it is a bit different.

In case anyone here is interested in having their Asus BIOS boot logo look like the Apple boot screen on real Macs, here's a BIOS boot logo I made with some added text for Asus' BIOS boot options. It has the correct aspect ratio once stretched to 16:9 displays. If anyone's interested I can make other aspect ratios too. To replace your BIOS boot logo you'll need to grab the Asus Update utility from Asus' website. That utility only runs on Windows.

Great guide, thanks for the help getting Mountain Lion to work.

I'm curious, though, 48GB of RAM?!?! I've got the same Mobo and believed the limit to be 24GB.
