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. (Is only if you have a Sandy Bridge-E if you have a Ivy Bridge-E skip this step)
 
Clover 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 select "KernelPm and AppleIntelCPUPM" on Clover Configurator in the "Kernel and Kext Patches" section (Is only if you have a board with msr lock if you have a Asus or Asrock skip this step)

 

3. Finally we need to download the following dummy kext and put it in /Library/Extensions/

LegacyX86PlatformPlugin.kext

 

4. Now is time to create it a SSDT for our cpu.

 

a. If you have a Sandy Bridge-E download this zip file, Inside you will found your SSDT

X79 SSDT.zip

 

b. If you have have a Ivy Bridge-E you need download the ssdtPRGen for your CPU.

curl -o ~/ssdtPRGen.sh https://raw.githubusercontent.com/Piker-Alpha/ssdtPRGen.sh/Beta/ssdtPRGen.sh
chmod +x ~/ssdtPRGen.sh
~/ssdtPRGen.sh

 

5. Download Hackintool open it and go to the "Utilities" section and at the bottom select "Rebuild KextCache and Repair Permission"

Actually I have dual E5-2667 v2 on C602. And I have enabled PM on 10.15.6 without touching the system folder. All I have done is using the aml from ssdtPRGen and add -xcpm in bootargs. I think this method only works with IVB-E.

-xcpm does not work since high sierra.
