Thunderbolt Ethernet not working after Yosemite...

Upgraded last night to 10.10, and now my Thunderbolt Ethernet adapter has no MAC address, and my MBP appears to think the cable is unplugged - it's not, and worked fine when the MBP was running 10.9 yesterday. Things which haven't worked:

 

  • Deleting and re-adding via Network Preferences
  • Changing default IPv6 to Link-local only
  • Rebooting with the thunderbolt adapter in
  • Rebooting with the thunderbolt adapter not in
  • Switching the thunderbolt adapter to the port further from the hinge and back again
  • Unplugging and replugging the ethernet cable
  • Plugging the ethernet cable directly into the wall jack instead of the hub it has always been plugged into
  • Unplugging and replugging the Thunderbolt
  • Changing Location to "Work" from "Automatic" and back again

Update - the same ethernet cable directly connected to thunderbolt port via "dongle" works as expected in Yosemite, without changing anything else. The bug seems to be with Yosemite's ability to detect the ethernet jack in the monitor itself through the thunderbolt connector. perhaps a firmware update is needed?

Same issue and solution for me. Before that the screen´s logicboard was replaced by Apple, so it seems like they are not even aware of the problem.


I'm considering contacting Apple and asking for a free ethernet dongle, so that I can get the original functionality back of the screen.

Possible solution.

I had the same issue.

Firmware is not the issue.  Mine worked before and after Yosemite was installed so you may have another issue.

I have the same problem with the display Ethernet connection.  I spent $29 on an apple help telephone call today without any resolution other than advice to take the display into the apple store for repair!  In addition to the Ethernet issue, there is no power coming through the lightning connection to my macbook pro so I have to connect my magsafe power cord to the laptop.  What happened to Apple reliability and backing of its products and software!  I am very disappointed to have purchased three (3) thunderbolt displays for my macbook at different sites and have such basic functions fail without supported remedy.

I feel like I have stumbled into some PC related nightmare.  This is not supposed to happen with Apple.

Problem of last two days that Apple support could not help with:

First, I have been unable to install thunderbolt 1.2 firmware update for the past month from my MacBook Pro Retina.  I tried installing from my old MacBook Pro after I recently updated its operating  system and apps.  It worked!  I was able to install the firmware.

Another problem I discovered yesterday was that the ethernet port from the thunderbolt would not connect to Ethernet.  It would connect if I used a lighting port to Ethernet adapter from the lightning port on the Thunderbolt display but still would not connect if I just connected the Ethernet cable to the Ethernet port on the thunderbolt (it worked from the old MacBook). 

So, I looked at the IP address indicated when the old macbook connected through the Ethernet and MANUALLY entered that IP address into the new MacBook Retinal thunderbolt Ethernet setup and it connected!  It has to be some Yosemite software glitch.

Still have no idea why the old MacBook would do the firmware upgrade and the new one would not.

Same exact problem with my macbook pro retina from end of 2013 . I haven't been able to solve it yet and it's really bugging me because I can't take advantage of my 200Mb/200Mb connection.

...but these seem to be all 3rd party USB ethernet adapters and nothing to do with the Thunderbolt adapter of the thread - or am I missing something?

 

I have the same blooming problem, it seems to be totally hit and miss whether the adapter works or not. 

 

I thought is was a faulty adapter, so even bought a second one for my MacBook Pro, so a bit more profit for the most profitable company in the world for a non working device.  My ethernet cable works fine to an old apple USB adapter but is 90% useless with Thunderbolt.

 

Renewing the DHCP lease occasionally works, but totally unreliable, at the moment it fails.

 

Still looking for a reliable solution.

 

Come on Apple, please sort this out, you have a connector policy of turning everything you can into adapters and dongles rather than building them in, so you end up with a slim laptop and a bag of adapters to carry around, and then when they don't  even work - doubly annoying.

I had a similar problem connecting my 15in mid-2014 MacBook Pro to an Ethernet cable via the Apple Thunderbolt dongle, but I may have stumbled on a workaround.  In System Preferences | Network, I created a new location.  Still in System Preferences | Network with the new location selection, I deleted all the "services" in the left window pane so it was completely blank.  I then clicked on the plus sign at the bottom of the pane, selected "Thunderbolt Ethernet", then configured the IP address, subnet mask, router address, and DNS server address, clicked "Apply," waited a few seconds and...the light turned green, and I was back in business.

This solved my problem. Over the weekend, I got tired of having to remind my laptop that I was home and created two new locations in Network Preferences. Somehow, that confused my MacBook Pro. So, I deleted my "Home" and "Work" locations and stuck with Automatic. The Ethernet via the thunderbolt display started working again.

it's possible no two brands of Thunderbolt adapters are alike. I've been using the USB to ethernet adapters without incident and updating the drivers via bluetooth when they wouldn't connect out of the box, but I've read enough negative reviews of the Thunderbolt display adapters and networking adapters to be concerned about introducing them to production macs in our office.

Hi,

 

I struggled with this issue for some time as well, but arrived at a solution related to a few comments above.

 

For me, Thunderbolt Ethernet appear 'not connected' not matter which settings I played around with (and despite it being connected).

 

It ultimately turned out to be directly related to location settings.  When all were deleted, and I reverted back to 'Automatic', thunderbolt started working again.

 

  1. Load 'Network' settings.
  2. With WIFI enable, click on the 'Location' dropdown in Network
  3. Click 'Edit Locations'
  4. Remove everything but Automatic.
  5. Turn WIFI off.
  6. Plug in thunderbolt ethernet
  7. Click on Location-->Edit Locations
  8. Remove everything but Automatic.
  9. Click 'Apply'.

For me, thunderbolt was immediately detected and everything reverted back to normal.

 

Hope this helps.

Dear WISE221,

 

You saved my day. God bless you child!
