This guide is for get a working Power Management on any X79
1. We need to patch the AICPM with the OMNI patch otherwise it will never work. I made a command file for this, Open with double click a type your password. (Is only if you have a Sandy Bridge-E if you have a Ivy Bridge-E skip this step)
Perl patch:

Clover patch (If you prefered to use the clover patch not need to use the perl patch)








Using clover configurator is easier. Your clover configurator have to see like this.

2. We need to patch the Msr lock. For this we need download the following script. (Is only if you have a board with msr lock if you have a Asus or Asrock skip this step)
NOTE: Clover has the MSR lock patcher but for some reason does not work with X79 platform.
3. Finally we need to download the following dummy kext and put it in /System/Library/Extensions/

Thanks stinga! I'm not planning on putting this on my X79 for a while but it's great to know there's a patch for my 3930k ready.

Thank you for the quick update, was willing to give this a try and also APFS and boom luckily you've got us covered for the Power Management... will try this over the week-end on my dual Xeon and report back.

Hi @stinga11,

First of all, thank you for all your help all these years. If you must know, your posts regarding X79 has been my go-to source in installing the latest OS every year. This High Sierra has been the hardest for me. Actually, even Sierra's 10.12.6 is. I'm not sure what really changed after 10.12.5, but I've wasted days to make it work to no avail. FYI, I'm using a 4K monitor and the best configuration I can get for 10.12.6 is it boots to the desktop except my 4K monitor is only at 30Hz. So it's unacceptable so I have to return and stay at 10.12.5.
Anyway, my problem now is since I can't even make 10.12.6 work, it's a lot harder for me to make 10.13 work. In fact, I've spent about 3 days already and I still can't even get Clover to finish the boot sequence just to even get to the Installation part of High Sierra. And this makes me wonder: What changed exactly? What additional steps should be done to make High Sierra work for our X79 systems this time? (My proc is 3930K btw if it matters) What SMBIOS is appropriate now that could make my 4K monitor work at 60Hz and boot into desktop? Other new info we must know?
So, here I am asking for any help from you if you could give me tips/suggestions on how to make High Sierra work for my Gigabyte X79-UP4. I believe you have a different mobo, but I'll take whatever tips/suggestions you can give me just so I could be on the step towards the right direction.
I would really appreciate a reply from you mate! Thanks in advance!
