I patched the ACPICPUPM and ran the new ssdtPRGen for Sierra 10.12.1

the drivers or kexts are loading as before.  Power Off would not happen.  The system would halt and restart.

Been using Clovers Fix_Shutdown, Restart Reset values and played around with ACPI fixes and adds.

 

However I'm getting ready to test "shutdown" in a few.

 

I set the Kernel PM.  but at first was unsure because of the information.

 

Should I use "Kernel CPU?"  

 

I have checked in Kernel and Kext Patches:

 

AppleRTC

AsusAICPUPM

Kernel PM

 

These three only, but after patching with the script do I need to check the AsusAI in Clover config.plist?

 

I have SSDT sorted have 4 total as a result of ssdtPRGen in Patched folder + DSDT patched.

 

I have DropTables DMAR, SSDTCpuPM and SSDTCpuIOst

 

Drop OEM  checked

 

plugin type 0

 

Sorted SSDT's

SSDT.aml

SSDT-1.aml

SSDT-2.aml

SSDT-3.aml

 

Patch ACIP and Halt enabler

and Reset Address and Value to Mac

 

I noticed that ssdtPRGen uses my patched DSDT.  Should I put that into the patched folder?

 

Thank you for your guidance.

I found your other site and downloaded the files:  ACPI, RTC, and kernel for 10.12.1.

 

In my config.plist what should I check and uncheck?

 

thank you very much!

 

Mak

Herve'

 

You're a genius!

 

My system POWERS OFF! 

 

Mac OS X Sierra 10.12.1

 

Kernel 

AsusAI

AppleIntelCPU

 

what should I do for my Clover config.plist?

 

I can send you my files?

why i am using i3 3240 but with untouched mach_kernel but also can using power management?

Did you read p1 of this thread?

 

Sandy Bridge and Ivy Bridge CPU power management operates through AICPUPM kext. So you need to patch the kext:

1. if you use Clover, apply/activate the AsusAICPUPM patch
2. if you use Chameleon/Enoch, patch the vanilla kext using the script provided on p1. Alternatively, replace the vanilla kext with a pre-patched copy or place the pre-patched kext in /L*/E*. If you up' the kext version to, say, 9xx, you'll sustain OS update without any CPU power management KP. In either case, you'll need to repair permissions and rebuild your cache.

CPU Power Management is handled by the kernel for Haswell CPU and beyond, so the vanilla kernel prevails in your case.

Thank you so much,I have power management by using Clover,but he is not clearly say Sandy Bridge and Ivy Bridge only need kext patch and Haswell need kext and kernel patch

The AICPUPM kext patch is for SB and IB CPUs only.

 

It's not required for Haswell CPUs and beyond. Those require the kernel patch, nothing else, i.e. since CPU PM is handled by kernel, the AICPUPM patch is not required.

so I do not need patch kernel and AICPUPM because i have ivy bridge?if I have haswell or skylake i need patch kernel,but no need patch AICPUPM?

Hi

 

I have a Sandy Bridge i5-2400 (Sandy Bridge) currently running Sierra with NullCPUPowerManagement.kext. To achieve working PM, Can I just apply the AsusAICPUPM patch on clover even though my machine is not an asus?

 

Do I also have to remove NullCPUPowerManagement.kext too?

 I know its been a long time since this post but had question about my processor E5-2697v2 Ivy Bridge 12 core.  This is the same processor you can upgrade the real MacPro6,1 trashcan to . Would you know offhand if this processor is natively supported by XCPM or AICPUPM?  I have an Asus X79 Sabertooth MB with that processor and although CPUPM seems to be working fine, X86PlatformPlugin loads and CPUPM is handled by AICPUPM and if XCPM is used natively on the real mac I am at a complete loss as to why it does not launch for my CPU?

 

Edited Next Day:

 

I got the answer looks like the real MacPro6,1 is natively using AICPUPM kext and not XCPM, Ivy Bridge-E
