Fenvi FV T919 (Broadcom BCM94360) working except Apple Watch unlock (Catalina)

The strange thing is that it does work for some people. It worked 1x time for me. What I noticed is that 1 out of 20 boots bluetooth devices can not connect and i need to restart one or two times. It just is not 100% stable which might be an due to some usb conflict. As I am quite new no sure how to debug

For me, everything works as long as the watch is connected via bluetooth ("Connected: Yes" in System Information > Bluetooth). Uncheck/check "Use your Apple Watch to unlock apps..." in System Preferences > Security & Privacy, to force the AW to connect. If I leave the computer (and BT disconnects), everything has stopped working when I return to the computer.

On a real Mac, the watch is NOT connected all the time ("Connected: No" in System Information), but can still communicate with the Mac somehow.
 
I solved this issue by disabling the serial port on BIOS settings (it's hidden under SuperIO settings or something like this). Now the unlock with Apple Watch feature works fine.

Unfortunately the option has been removed on recent bios versions for newer boards like z390. Deleting the serial port does not help so it should be disabled with a ssdt which i have not been able to achieve.

Seems this is 100% related to a bios setting which Gigabyte has removed which allowed to disable the serial port.
There is a beta bios available for multiple Gigabyte motherboards that brings this back. Solved the issue completely for me. More info in the below thread where there is a link to the beta bioses

A friend of mine has the z390-ud and there’s the option for the serial port (it’s under SuperIO) without beta

the option is under Peripherals => superIO?

i don't even have Peripherals in my bios, i think i have to use a beta version.

maybe the situation differs in z390-ud :crazy:
