No difference. I think it’s a bios update problem.Hmmmmmm, Ok try disabling SSDT-SBUS-MCHC and see if helps any on your side.
If your bios is up to date then I doubt it will make any difference but still it’s worth a try.
two months ago I had hackintosh with f33a and no problem.
I ditched hackintosh, and updated the bios for windows problems. now that i have decided to reinstall big sur i have this problem (even with the same efi i put aside, which worked two months ago)
