  • Made a backup of the motherboard BIOS with a CH341a SPI ROM reader. This is just a precaution.


Why? You can use the official Gigabyte BIOS version from their website if you want to revert, can't you?

Mmm. Will this BIOS adaptation destroy TB under Windows?
If you flash official Gigabyte firmware downloaded from their website, with CH341a programmer, you loose :
  • your Ethernet MAC address (displayed as 88:88:88:88:88)
  • your current BIOS setting
  • and all NVRAM datas (installed by macOS on installation)

But can't you just use GB qflash with the official BIOS firmware?

This may interfere with some copyright protected software, what do you think?

No, this only overwrite whole firmware with a standard's one.

Downloaded firmware is flashable with Gigabyte tool like Q-Flash, which overwrite some regions and keep your personal datas (Serial number, MAC address,..) and profils.
I don't remember if NVRAM is also cleared after Q-Flash firmware update.

Older copy protected software would check your MAC address(and other stuff). So if this is reset, things go wrong.
Native Instruments even checks your processor speed. If this field is zero(which is not uncommon on a hackintosh), it will prompt you to re-register the software everytime you try to use your (legit) NI software.

Since I'm a tinkerer but also work around lots of activations I've got a designated USB drive for activations. If possible, it's a great move allowing you to either move from computer to computer like an iLok or to prevent de/re-activation.

Check NI support if interested.

Interim Update:
  • ThunderboltUUID in IOReg is currently zero.
    • We want to address this problem first.
  • Apple Thunderbolt to Gigabit Ethernet adapter is not working in Big Sur.
    • We will address this problem second.
Interim Update #1B:
  • ThunderboltUUID problem has been fixed with a new version of the experimental BIOS.
  • Now focusing on Apple Thunderbolt to Gigabit Ethernet adapter.

All right :)!

For Apple Thunderbolt to Gigabit Ethernet adapter, can you screenshot IOReg DSB1@1/... /ethernet@0 ?
