When I install the thunderbolt Ethernet adapter with it connected to a switch the switch shows the gigabit connection with the LEDs but the MacBook doesn't show the connection as being active. Looking at the Mac under System I see Thunderbolt 1 and 2 as being inactive. OS is 10.12.6 Beta and HW is MacBook Pro Retina 15 inch Mid 2015 Any ideas?
