Hi MaLd0n,
I have running Hackintosh Sierra Zone, and it seems read kext from /system/library/extension/.
When I unplug the Hackintosh, the nullcpupowermanagement is no longer showing in the log. But still ended with same error message. Will come back to you with latest screenshot.
i have other question, is there any way to explore clover's EFI folder with windows operating system? all this time i used hackintosh to explore the bootable Olarila's EFI folders.
