I have a MacBook Pro running 10.10.5 and a Thunderbolt Display. I access the internet using "Display Thunderbolt", my ethernet cable is plugged into the display and the display Thunderbolt cable is plugged into the MacBook Pro. Everything works fine.
However, I need to use my MacBook Pro on the ethernet network without going through the display. I have a brand-new Apple "Thunderbolt to Gigabit Ethernet Adaptor", but when I plug it into my MacBook Pro's thunderbolt port, the MacBook proclaims that "None of the member interfaces is connected."
What troubleshooting steps can I take to diagnose the problem and get my MacBook Pro on the ethernet network?
ETA: On the advice of emotality below, I have tried the following without success.
- Plugging the ethernet cable into the Thunderbolt Ethernet Adaptor which I then plugged into the Thunderbolt port on the display.
- Adding, by hand, a new Thunderbolt Bridge service.
- Plugging the Thunderbolt Ethernet Adaptor into both ports on the MacBook Pro
I have also tried setting the "Configure IPv6:" drop down to Link-local only".
Also, to clarify, I need to do this as I need to use my MacBook Pro in another location which has an ethernet connection but no wifi and I can't take my monitor there. (And because it should work, should it not?)
