Downloading macOS Big Sur Public Release and will be testing all the things that i can possibly test.
Once all checks have passed, i will publish the OC guide.
A few suggestions regarding SMBIOS (supported) for Big Sur ? for HD4000 users i would suggest the Trash Can as i mentioned on some earlier posts and had everything working buttery smooth.
Unfortunately i don't have any Dedicated GPU to test.
@LisaAlterEgo what are you SMBIOS choices you would suggest and give some brief description about pros and cons between each other.
I would need this so i can include all the SMBIOS choices on USBPorts.kext
Thoughts on Power Management with OpenCore and suggestions ?
Personally i am still using that SSDT i generated of my i7-3770 and haven't had any issues with it.
@Asural im not 100% sure to which dialog are you refering, but i think you mean the Power Menu when you hold the Power Button like this one? :

If it is this one, then it is because LPC/LPCB Controller is not loaded, i believe
@LisaAlterEgo described this one a few posts ago, it is necessary to be loaded.
@Sniki,
I was trying to generate a SSDT-UIAC for USBInjectAll that would
alleviate the need for separate USB configurations for various
models and that would be minimal. I've attached an experimental
EFIexcerptUSB that has all the changes necessary to use it. This
is an alternative to USBPorts with its plurality of IOKit Personalities.
Inside of the uncompressed EFI folder, there are two ACPI files,
the SSDT-UIAC.aml and a combined SSDT-EC-USBX as provided by
ACPISamples. It incorporates and replaces SSDT-EC. There is also a kext,
Rehabman's USBInjectAll version 7.0 (for legacy hubs on iMacPro1,1).
There's also the config file changes, which rename EHC1,2 to EH01,2
among other things.
I tested it with SMBIOS for iMacPro1,1 (Big Sur), iMac18,3 (Big Sur),
and MacPro6,1 (Catalina).
For the first two, it gave a minimal USB with 6 ports on EH02, and
4 ports on EH01, HP15-HP18. I tested the EH01 ports using a media
card reader plugged into the Media1 or Media 2 header on the
motherboard, in both the SFF and CMT form factors. My media card
reader has a USB2 port and 5 media card ports, of which I've only
tested the CF/MD reader. When I have a USB2 stick and a CompactFlash
card plugged in, they appear on HP15/HP16 for one header, and HP17/HP18
for the other header. I also tested the SSDT-EHCx_OFF in the ACPISamples
of OC 0.6.3/Docs, and it can be used to turn off EH01 if desired.
Unfortunately, I found that the MacPro6,1 assigns another PRT1 on port
1 of EH01, that looks like the XHCA port 1 of the iMac13,2 or MacMini6,1.
I've also provided an alternative SSDT-UIAC that defines PRT1 as an XHCA
UsbMux port for the MacPro6,1. I don't know what its doing, but the
MacPro6,1 wants a portType 2 port there.
Update 11/28: My mistake... There are two versions of SSDT-EC-USBX and
I originally included the wrong one. The updated one is from ACPISamples
and incorporates SSDT-EC. I also put in the SSDT-ECHx-OFF for disabling
EH01.
