Tested with Big Sur but probably will work with Catalina as well.

I am not a specialist and I spend a lot of time to make my system work.

In my opinion, I assume that it is a very common low budget hardware combination.

So, I am placing here my files to save you some time.

You have to import your custom System Serial, UUID, and MLB numbers.

Working everything except sleep/wake (you have to unplug and plug the display cable).

Easy fix = Disable your display turn off in power settings.

Of course, if anyone find an 100% solution, I will be gratefully to hear about it.

There are two versions:

Final = For exactly same system with theme, modded USB3 and LAN kexts

(The OpenShell and Clear NVRAM tools are hidden under spacebar)

Debug = For experiments on similar systems with detailed debug info and original kexts

(You will probably need to generate your own ACPI SSDTs)

=============== EXTRA DETAILS ===============

  1. Due to security reasons Apple does not allow non certificated extensions to get installed. So, I have put NVRAM/Add/7C436110-AB2A-4BBB-A880-FE41995C9F82/csr-active-config = 03000000. You can change it to 00000000 if you facing updating problems.
  2. If you experience boot loop after partition scheme modification consider of changing the SecureBoot flags (not tested).

=============== HELP ME AND OTHERS ===============

If you have any success to other systems with those EFI folders please mention it on Issues section among with the tweaks you have made.

Thank you.
