GUIDE How to Enable Intel CPU Power Management on X79/C606 Motherboards [Sandy Bridge-E/EP and Ivy Bridge-E/EP]

That''s a very common issue.
To fix it, follow the steps below.

Extract the ACPI set from your system.
Copy the SSDT1-cpu-def file and the apic.aml file to Desktop.
Rename the ssdt to dsdt.aml

Thanks mate! that did the trick with 21.5
Here is the log: https://pastebin.pl/view/9d1b30b9
The new ssdt looks much healthier than the previous one.
Somehow after restarting x86platformplugin is not loading any more with the new ssdt :/

edit: they seem to address different addresses if I'm not mistaken.

Kextstat and Kextcache are two different things.

Yeah, sorry for the goof up.


post@DESKTOP-1S52J6M ~ % sudo Kextcache -i /
Kextcache -i /
Executing: /usr/bin/kmutil install --volume-root / --check-rebuild
rebuilding local auxiliary collection

Is this result ok?

For Catalina fix, is the #3 just a place holder? The FIND and REPLACE strings are identical.
