[Success] Yosemite : ASRock X79 Extreme 6, i7-3930K, MSI R9 280X Gaming

[BLACKTHiEF]

Hello everyone, im here to confirm that i have successfully installed Yosemite on my PC, and it's working very well.

Hardware :

Operating System Mac OS X Yosemite 10.10.1
Motherboard ASRock X79 Extreme 6
Processor Intel Core i7-3930K @ 3.20 GHz
Graphic Card MSI R9 280X Gaming
Memory 24 GB 1333 MHz DDR3


Boot Flag Used :

I used the "npci=0x2000" to reach the OS X Yosemite Installer, then after i successfully installed it, i used the same boot flag to boot into my HDD installation to complete it.

After installing Multibeast's stuff, i have added the boot flag "npci=0x2000" to the "org.chameleon.Boot.plist" directly under Kernel Flags! in my case there was already a Kernel Flags string so i added two new lines that i have marked in Blue&Red!!

Right after the installation of Multibeast's stuff put all the AsRock X79 Kexts in the Desktop and put KextBeast with them too and install all the Kexts Reboot and you are now good to go and all your stuff is fully working no DSDT patching no DSDT at all needed no nothing.

</plist>

After adding the Boot flag to Chameleon Boot file, installing all AsRock X79 Kexts. i restarted my Computer. While my computer was about to boot i have received this error :

Boot0: GPT
Boot0: test
Boot0: test
Boot0: done

Fixing the boot0: GPT error :

Boot to Yosemite using the USB and Download Chameleon Wizard, run it, install "Boot0md" go back and launch Multibeast reinstall the Chimera boot loader another time, and BAAM!!! no boot Error again!!

Enjoy Yosemite

Hi BLACKTHiEF,

Congratulations on the successful build!

I have a very similar setup and have been having quite a bit of difficulty:

ASRock X79 Extreme6
i7-3930k
Sapphire Radeon Dual-X R9 270

Do you by chance have the Multibeast .mb file you used, or perhaps a screenshot of your MultiBeast configuration?

I keep doing something wrong, I've been referencing the only other Extreme6 success story I've found on this forum: http://www.tonymacx86.com/user-buil...-i7-3930k-4-2-ghz-32gb-geforce-gtx-770-a.html

Did you use the DSDT file he references in that post to do your installation?

Thanks a bunch!

How's the 280x treating you?
Flawless? Any hiccups?

Were you able to get C states working correctly?

Also, thank you for the Voodoo kext, it works flawlessly.
