#THUNDERBOLT TO GIGABIT ETHERNET ADAPTER MAC ADDRESS MAC OS X#
I have Mac OS X 10.11.3 installed on a mid-2014 Retina 15" PowerBook. This process worked reliably, but it is not something you want to do several times a day as you move around an office, attend meetings, etc. If I wanted to use wired ethernet, I would have to delete the files again and restart the machine. After that, the the Network pane reverted to not noticing the Thunderbolt-to-Ethernet adapter at all, even though one could see (via dmesg) IOThunderboltSwitch messages for each physical plug/unplug event. Unfortunately, this solution worked only briefly, for one (sometimes two) plug-ins of the adapter.

The only thing that had helped at all was deleting files from /Library/Preferences/SystemConfiguration - sometimes deleting just ist, sometimes all files except - and restarting. I had first tried the solutions offered in this thread and in similar threads. Except now with wired ethernet working properly. My Mac was back working in under 45 minutes, with all settings and files intact. Thanks for all the suggestions! I was able to resolve this problem by entering Recovery Mode, turning off WiFi, testing that the Thunderbolt to Gigabit Ethernet Adapter was working in Recovery Mode, then selecting the Recovery Mode option for re-installing OS X.

It also doesn't seem to depend on the version of OS X (at least within the past few years)., and may not be triggered by firmware or driver updates. It appears that it is not terribly hardware-specific. This problem and its close relatives have been noted in forums for some years. After a couple of minutes the Ethernet/Thunderbird lashup made it all the way through the milestones, and the connection was finally good. I restarted all switches, the router, and the cable modem (possibly overkill to do everything, but it was easy and it was a way to reset all devices)-and waited. When that didn't work, the screen message was to restart my router. What worked for me was to turn off wireless, get rid of old locations, start a new one, and then go through building the connection. In "Network" a green dot displayed for the dongle, but there was an intermittent message indicating a (nonexistent) IP conflict. Home LAN going through two switches and a router to get to a cable modem. Similar/same problem: Ethernet-Thunderbolt dongle plugged into Macbook Pro. My adaptor is the genuine Apple unit, not an after market.Īny ideas? Any others have this issue? I'm hoping it's not a hardware problem.

I have tried setting a specific location "work" for the ethernet connection so that I can select that state when I need to use ethernet. I have the impression that it doesn't work the same way every time, but I haven't been systematic enough yet to be sure.

Then I go to the "advanced" window and click "renew DHCP lease." It doesn't connect right away, but when I close the advanced window, it will usually connect to the network. I shut down wifi, doing only this doesn't solve the problem the machine still says that the ethernet cable is not connected. The laptop does not recognize that I have plugged in, and to solve the problem, I have to open my network preferences and try to force it to connect. I usually use wifi to connect to my network at work, but sometimes signal strength is low and I plug in my Thunderbolt to ethernet adaptor. I have a rMBP 2.3 gHZ, 8 gigs RAM running OS 10.8.1.
