I have a different CPU, i.e. the 2670 and I had some Kernel Panics where a CPU thread crash was reported. I found a SSDT from Rampagedev and ditched the DSDT in favor of mine and no issues so far, so it may be slight differences that can make a difference. Anyway I couldn't"t get LAN to get button true before, which is required to use Face Time and iMessage and Handoff properly, now everything works as expected.
 

There were also no syntax errors in the DSDT generated from Origin

Questions:

 

1. Can I use your DSDT.aml or do I need to generate a new one?

2. is this the motherboard?

 

Hi, Courage2000.

 

Unfortunately, you can not use my DSDT.aml. The probability that the system will start is small. Even if it starts, it will not be the correct operation of the macOS.

If you want to use this hardware for macOS, you must go a long and difficult way to make your own DSDT.aml and config.plist settings.

I have successfully installed macOS Big Sur 11.2.3 on this PC (see the first post in the thread)

Any of the MacPro6,1 or MacPro7,1 SMBIOS can be used. Both alternatives work equally stable. System performance and power consumption is similar to Mojave. All devices and technologies are working fine.

 

In addition to the Open Core v 0.6.7 recommended settings for this platform (Chinese motherboards X79 + Sandy Bridge-E CPU), see https://dortania.github.io/OpenCore-Install-Guide/config-HEDT/ivy-bridge-e.html#sandy-and-ivy-bridge-e , you need to use the following:

 

1. New set of patches for proper functioning CPU Speed Step and Turbo Boost on Big Sur:  https://www.insanelymac.com/forum/topic/346988-sandy-bridge-e-power-management-big-sur-1121

 

2. When you update SMBIOS from MacPro6,1 to MacPro7,1 you additionally need

- update USBPorts.kext (If you use this method of USB settings)

- fix MacPro7,1 Memory Errors, see https://dortania.github.io/OpenCore-Post-Install/universal/memory.html#fixing-macpro7-1-memory-errors

- use ProcessorType = 3842 in config.plist
