Using OC 0.6.3. macOS 11.0.1
WiFi/Bloothtooth Fenvi T919 working fine,
However, the once native PCI-e Ethernet BCM57762 card is no longer listed in Networking. Has Apple dropped support for the BCM57762 in macOS 11 big sur?

— Resolved.

It uses the AppleBCM5701Ethernet.kext that is included in Big Sur. So it should have worked as it does on Windows, and macOS 10.X.X

I would appear the card had some issue with Big Sur + openCore that after installation it would no longer show up in macOS 11 Big Sur, macOS 10.15.7, or Windows 10 Pro. Not sure yet if this was due to openCore or a firmware update when Big Sur was installed. Anyway, I reset the bios, and changed some settings in openCore and bios and it’s back on all including Big Sur. Very strange. I will continue testing and try and recreate the issue.

Anyway to confirm, it is still fully supported.
