After update BigSur from 11.6.2 to 11.6.3 Usb to Ethernet adapter, Realtec 8153, stop working. I have just (5th jan 2022) updated to BigSur 11.6.3 and Usb to Ethernet stop working. On previous version 11.6.2 worked well. It is USB-C hub providing by Phillips Brilliance 329P. I tried to install Realtec 8153 drivers, after reboot adapter was working but after next reboot stopped working again. Any suggestion? Thanks
BigSur 11.6.3 update Realtec adapter stop working
You should contact Realtec support.
Where did you get 11.6.3 ? I do not see any proposal for upgrade from 11.6.2 in system Preferences. Would it be reserved to some countries ?
Hi, It was proposed by normal MacOS SW actualisation. There were some security update and Safari update in it. I am on Mac Mini 2018.
