Q: Ethernet adapter not working
I can't get the Thunderbolt Gigabit Ethernet Adapter (MD463LL/A) to work on my 2014 15-inch Macbook Pro (11,2).
When I plug the device into either thunderbolt port I see nothing on the screen. However, when I look under the "Thunderbolt" section in System Information, I see the following:
When I look in network preferences, I see nothing:
And when I try too add a new network interface, Thunderbolt ethernet is not listed:
I have searched around on this problem, and some have recommended deleting all interfaces, killing the networkpreferences plist and rebooting. I've tried this, and it didn't help.
I also returned the dongle assuming that I just got a bad copy and purchased a new one. Same problem.
Any ideas would be much appreciated.
MacBook Pro with Retina display, OS X El Capitan (10.11.5)

It is possible that these kexts are installed under directly in /System/Library/Extensions or under /S/L/E/IONetworkingFamily.kext/Contents/PlugIns, so be sure to check both locations.
Your thunderbolt is working as it is getting detected and running.
If you remove anything from either of the folders, run Kext Utility reboot and try again
There is a tool named Kext Wizard that provides a GUI and perhaps you can find it easier. It should be in the loaded tab. Not sure as I haven't used it in a while.
