I think there is a way to downgrade capsule BIOS but I think it’s not simple. Anyone?Hi @CaseySJ. I was F9 before I decided to go with Mac OS. So it is not possible to revert it as you know. My problem is not Mac OS specific and I don't care USB 2.0 too much. But I really need USB 3.0, USB 3.1, USB 3.2 Type C devices to work on Thunderbolt 3 port (To boot from an external drive on Mac OS, to use as extra storage on windows). I set "Thunderbolt Usb Support" as enabled on BIOS but either in BIOS or in Windows-Mac OS it just does not work. I can't use my type C external drives anywhere if they are connected on Thunderbolt ports.
Do you know the reason and the solution? How could Gigabyte kill USB support on Thunderbolt 3 ports with BIOS update? If the reason is just the BIOS update, it is unacceptable if GIGABYTE limited the Thunderbolt ports to be used by only Thunderbolt devices.
As for a possible reason: a bug in the latest firmware revisions?
