10.9.2 knocked out Thunderbolt/Ethernet bridge

Now I cannot be the only one. SInce updating to 10.9.2 my ethernet via the thunderbolt bridge is not working.
Does anyone have any thoughts on what might be going on with it and what steps I can take to troubleshoot.
Thanks

I have the exact same issue (rMBP 15" 2012). It worked perfectly fine for me before the update and now, even after so many methods in trying to fix it, there is no way the thunderbolt ethernet connection is getting established...
I have noticed a subtle flash on the Network pane when plugged in and removed, but this doesn't seem to take a further effect on its purpose.
Would appreciate any legitimate ideas on troubleshooting this issue or even just having a fact established that this is a hiccup in the OSX Mavericks (10.9.2) update and there really is nothing we can do until this is fixed.
Thank You

Thunderbolt Ethernet bridge not recognised

I have an original Apple Thunderbolt Ethernet bridge (TEB) for my brand new MBP 13" retina Mid 2014 edition and I am running Yosemite 10.10.2. I connect to the internet via ethernet regularly to play online video games. I recently plugged in my TEB and found that it wasn't connecting me to the internet. I checked network preferences and tried to run diagnostics but in the network preferences it says there is nothing plugged into the Thunderbolt port. However, when I go to system information and under the hardware tab I selected Thunderbolt, with the TEB connected there is a little drop down menu named Thunderbolt bus and under it it says Thunderbolt to Gigabit Ethernet Adapter. If I remove the TEB, this drop down option is not there, which gives me the impression that the computer is recognising the TEB, but somehow something is wrong with the software that isn't allowing me to connect.
Further information before any of you suggest something simple because I've tried all the simple solutions
I went to the apple store with my TEB and asked them to check if it was working, they confirmed that there is nothing wrong.
I've also used a brand new ethernet cable, one that I know is working to connect to the modem. And obviously my internet is working because otherwise I wouldnt be writing this.
So if anyone knows what I can do to fix this problem please help!
I've used the app EtreCheck and here were the results, doesn't seem like anything is wrong

Thunderbolt ethernet en3 interface not appearing on MacBook Pro Retina

2012 retina MBP, with a Thunderbolt ethernet adapter. Fully up to date, including this week's Thunderbolt firmware update. Plug the Thunderbolt ethernet adapter into any port -- the kernel sort of sees it, but nothing ever provides a network interface.
Infuriatingly, I got it to work once after weeks of failure, but have never been to reproduce that fleeting success.
I've seen and tried the comments in three seemingly-relevant threads:
https://discussions.apple.com/message/19550825
https://discussions.apple.com/message/21335473
https://discussions.apple.com/message/17909404
Like other reporters of similar problems, it's visible just fine in the system info:
Thunderbolt to Gigabit Ethernet Adapter:
Vendor Name:    Apple Inc.
Device Name:    Thunderbolt to Gigabit Ethernet Adapter
Vendor ID:    0x1
Device ID:    0x8003
Device Revision:    0x1
UID:    0x000100020014E9B0
Apple Serial Number:    DTN22060026DWKHAR
Route String:    3
Firmware Version:    5.5
Port:
Status:    Device connected
Link Status:    0x2
Port Micro Firmware Version:    0.0.8
It's getting power, at least, because the switch link light comes on when a cable's plugged in.
And the kernel recognises it in either Thunderbolt port, at least to some degree:
IOThunderboltSwitch(0x0)::listenerCallback - Thunderbolt HPD packet for route = 0x0 port = 1 unplug = 0
[ PCI configuration begin ]
PCI configuration changed (bridge=58 device=5 cardbus=0)
[ PCI configuration end, bridges 14 devices 16 ]
But no driver ever gets loaded, and the en3 device never appears.
I've tried installing AppleBCM5701Ethernet.kext manually, which does nothing apparent. Unloading and reloading produces:
AppleBCM5701Ethernet:     ffff     ffff getAdapterInfo - Vendor is unknown
AppleBCM5701Ethernet:        0        0 start - getAdapterInfo failed, giving up
It's unclear if any of that is relevant or related to this adapter.
I've borrowed another physical adapter and tried that; it gives the same result.
https://discussions.apple.com/message/21335473 suggests creating a new Network Location. When I do that, the Thunderbolt Ethernet device (which does exist in my "Automatic" location) doesn't even appear in the new location. Clicking the [+] does not list it as an option to add.
https://discussions.apple.com/message/17909404 suggests resetting the SMC, which I've done in theory -- although I can find no documented way to know that the SMC reset actually occurred. Certainly there was no indication that I could see. So I'm not convinced that it did anything at all.
I'm out of ideas. This seems to me much more likely to be a software issue than hardware, at this point. Almost like it just can't figure out which driver it needs to load.
I humbly throw myself upon your mercy and wisdom.

I had this problem, too, and an Apple Support call and Genius Bar visit later, I had the answer: if you're using Network Locations that preexist your Thunderbolt display, it doesn't seem to auto-add the possibility of "Display Ethernet" to your available network ports. To solve this, either:
Create a new Location in your Network system preferences. It will finally detect the "Display Ethernet" and use it. It'll slowly change from disconnected to No IP to green-is-for-go.
or
Fix an existing Location by clicking the + to add a port and choosing Display Ethernet. It'll slowly change from disconnected to No IP to green-is-for-go.

Can't share Internet from Mac to AirPort Extreme via Thunderbolt Ethernet

Hey there!
I'm trying to essentially use a 2013 AirPort Extreme as an AP for the network. It's connected via WAN to a Mac via a Thunderbolt to Ethernet adapter.
I'm having a hard time telling OS X (10.10)/ OS X Server that I want it to take the Internet from "iPhone USB" and share it with "Thunderbolt Ethernet". With or without OS X Server's DHCP/DNS "help". I've been experiencing issues with Internet Sharing for years on OS X, so the fact that I'm having an issue today is no surprise, I'm just hoping someone out there has a solution.
If I go back to Internet Sharing in System Preferences, the "share Internet connection from" combo box is blank, rather than showing "iPhone USB".
Also, I'm unsure as to whether I should be using OS X Server... I know it's not necessary for simple Internet connection sharing, but I'd like to use DHCP and DNS services with this setup at least eventually.... Obviously just getting Internet to the AirPort is first-priority.
Any ideas?

Hello Kevin,
Let me try to get this straight, it seems like you want to bridge the fee-based wifi network and your home wireless network using your MB.
I don't know if you have done the following steps already on your MB:
1) Choose Apple > System Preferences, and then click Sharing.
2) Select Internet Sharing.
3) Choose a network service from the “Share your connection from” pop-up menu, AirPort in your case.
4) Select a networking service to share your Internet connection from the “To computers using” list, ethernet in your case.
Sorry, yes indeed it is straight from Mac Help titled "Sharing your Internet connection." and it sounds like you have done the sharing part already. You wrote about something wrong with your MB. It might be helpful to write what is wrong with your MB, AirPort Extreme, or your "other computers." Preciseness can definably help us help you.
May you solve the problem.

Thunderbolt ethernet not showing up in network preferences

this is happening with both my thunderbolt display and thunderbolt<->ethernet adaptor....
the ether net in the t-bolt display WAS working.... but was having probs with the ethernet adaptor while on the road, so I tried deleting the thunderbolt ethernet entry from the Network Preferences panel. Well, now when I hook up my thunderbolt Display, the option doesn't re-appear! So now I'm thinking there's something in the system that's keeping that from re-appearing in the network preference panel, and it could be the reason for both items not working.
The controller is recognized at a low level by the system - in system report I get:
Apple 57761-B0:

mDNS offload capable:          c8:2a:14:4f:a3:90
Version:          3.2.4b8
So it's a problem with the Network Preferences panel getting loaded, somehow.   I tried re-creating the kext cache, that didn't help.
Digging around a little in the system, I see this:
cd /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/
$ ls
AppleBCM5701Ethernet.kext          AppleYukon2.kext
AppleIntel8254XEthernet.kext          IOEthernetAVBController.kext
AppleUSBEthernet.kext                    Intel82574L.kext
AppleUSBGigEthernet.kext          nvenet.kext
But I'm out of ideas how to get the thunderbolt ethernet option back into the Network Preference panel. help?!

I also tried disconnecting the display and adding it back and rebooting - nothing worked.
But here's a bizarre twist: I show "Bluetooth PAN" connected and active, and it's coming from the Thunderbolt display! I can get online. Then I disconnect the network cable from the display, and test again - no network. So somehow, the driver for Bluetooth PAN is totally confused with the display Ethernet. In fact, the Bluetooth PAN shows connected, and "No PAN devices found". So I'm connected to a phantom device.
Maybe deleting the PAN and display, adding back the display, will get it to recognize it properly.
The short of it is I have Ethernet connected now through the display, but using the Bluetooth PAN device driver.

Thunderbolt Ethernet not working after Yosemite upgrade

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

the link provide above leads to http://plugable.com/2014/10/31/os-x-10-10-yosemite-ethernet-adapter-problems-we- can-help
...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.

Can't get ethernet bridge to connect to network

Hi
I am trying to connect my old iMac G3 (10.2) to my airport express network with an Aeropad Mini (an ethernet bridge powered by USB hub on my mac - made by Macsense).
The network is seen successfully by an iMac G5, an Intel Macbook and a PC. The connection occasionally works but more often than not it does not see my airport express - instead it connects to a self-assigned IP. Sometimes it connects then drops off halfway through. Other times it just will not connect at all.
There are no drivers and you set it up via your browser. I can connect to the status and set-up page (192.168.1.50), after entering all the Aeropad info manually, and most times it can see my Airport Express (via the Site Survey on the set-up pages). but sometimes it does not even get that far. I reset the aeropad and restart the mac many times, and sometimes it works but mostly it doesn't.
I'm using channel 11 and it's WAP-encrypted.
Things I've tried:
updating the firmware from the macsense website
checking it's on client mode
manually entering the DNS address of my router - 10.0.1.1.
Trashing the internetconfig preferences from the library
making sure that ethernet is at the top of my network port configurations
Plugging it into a powered USB hub
Trying it on my MacBook (running Leopard).
Still can't connect - just a self-assigned IP - even on on the new macbook.
Any help would be appreciated as I really can't get this to work and it's beginning to take over my life!. I thought it was working after I entered the DNS address but it just went down again the next day.
Thanks.

This is probably repeating the steps which you have taken already, but I thought I'd put them in one place just in case.
Problem:
If you're able to see other wireless networks but not your own. (And it works with AppleTV version 1.x)
It can be any of the following:
1. No wireless signal/out of range (check your multicast setting and put this as low as possible, check the range with other wireless devices/moving your appletv closer)
2. The wireless SSID is set to invisible/private (use "Other" on AppleTV and enter the SSID manually.)
3. The AppleTV doesn't support the channel used. (Tune the wireless to use a lower channel such as those under 10.)
4. The AppleTV is not supporting the security of your encryption.
Troubleshooting:
1. First try setting up a basic wireless network with no security, no frills such as a high multicast rate or high channel number and as a basic wireless b or g network. Position the AppleTV next to the basestation and then attempt to make the appletv connect to it. (Do not use an AdHoc network with your mac, as the AppleTV doesn't see these.) At this stage you're just trying to see if the AppleTV is even able to connect to your hardware. If this doesn't work there is possibly a larger problem at hand.
2. If this works, then move the devices to their desired locations. (This checks that it's not a range/interference issue.)
3. If this is still working, then the problem lays in a configuration setting. Firstly enable a security protocol, avoid WEP. Keep adding settings, keeping changes from the default to a minimum.
If you can't get past step 1, then it could be an issue with your wifi base station. Try getting the AppleTV to connect to a different wireless basestation (perhaps borrow one from a friend or a neighbour's unsecured network.)

How do you determine the IP address of an ethernet bridge?

I've got a US Robotics ethernet bridge connected to a Mac running OS 10.3.9, and I'm trying to access the bridge's web browser interface. (Once I get to that interface, I'll be home free.)
The bridge does not have a default IP address, the connection software on its CD-ROM is PC-only, and USR tech support is baffled. So how can I find out its address?
I've tried looking in System Preferences -> Network, in System Profiler and in Network Utility, but it appears that they only display the computer's address, not the bridge's.
Thanks in advance for any suggestions.

I presume you are taking about the USR5430?
No, it's the USR5432, which unfortunately doesn't have a default IP address (unlike the 5430). The USR site has this to say about connecting to the 5432:
Macintosh and Linux Users
The networking device that the Bridge is connected to probably has some form of Web User Interface where you can view a client list. Refer to your networking device's documentation to determine how to view this information.
When you find the client list, locate the Bridge. You can do this by verifying the LAN MAC address that is on the bottom label of the Bridge and what appears in the client list. Write down the IP address of the Bridge for future reference.
Open a Web browser, type in the IP address of the Bridge, and then press Enter. This will open the Web User Interface of the Bridge.
The bridge only has an IP address when it is in
configuration mode.
That makes sense. And I am in fact trying to locate the bridge's address in order to configure it.
Nevertheless, thank you for the suggestion.

Request: Provide Ethernet Bridging to NON-WDS Networks!!!

I realize that the topic I am adding here has been discussed quite a few times and also that many comments were made on the issue at least as often. What I am trying to understand is this:
Why did the initial design of the Airport Express turn off or not provide Ethernet bridging in client mode?
My brother gave me the AE as a gift over a year ago and just recently I got a wireless router and dsl modem (in one unit) and was able to install the AE for the following usage (which I consider reasonable and 100% compliant to what was written on the box):
- stream airtunes to the stereo in the living room (ok)
- get my playstation2 online using the ethernet port (no way)
Now that I have gone through hours of internet searching regarding WDS, I see that Apple has not intended the AE for this usage as it is only possible using Airport units. Don't get me wrong, but I am not going to go out and buy another base station in the form of any other Airport unit (especially after reading the other threads regarding their reliability!) just to get the funtionality of an Ethernet bridge.
Bridging requires little to no additional intelligence in the unit other than mirroring the network traffic it is hearing on the wireless side. And that is obviously available since the WDS configuration offers that. I am aware of technical details (I built up the internals of a wireless ethernet bridge in a Hiperlan/2 network over three years ago at a research facility) and want to know why this is not done by default?? The AE is heating my living room as it is and I consider this a reasonable request for a new firmware edition - those who don't use ethernet bridging wouldn't notice a difference and the AE would finally fulfil what is promised on the box.
Thanks for your time and perhaps persuasion in handling this issue - I hope my AE lasts long enough to experience this firmware edition if it ever gets out there.

WRT610N v2- Which Ethernet Bridge to buy to go with it for LG BD370 BluRay player?

I have a WRT610N v2 router, which I LOVE. I need an ethernet bridge (to connect a LG BD370) Blu-Ray DVD player. I've spoken with Linksys tech support & I'm sad to say, got misinformed. I'd actually ordered a PLS300 (which I cancelled) when I found out there weren't any updates for it. I'm running Windows 7 Home Premium 64 bit.
The tech support person first told me I needed a WET610N & then changed her mind.
The WRT610N is located in the office about 15 yards from where I need to connect the ethernet support to the entertainment system. I also have a wireless printer (Lexmark Platinum PRO905 that is about 5 feet from the LG Blu ray player. Is the ethernet bridge going to interfere with the Blu ray player?
I'm just wanting to get connected to NetFlix. I've paid for this service since last spring but am just now getting around to sorting this out.
Any help would be greatly appreciated! TIA

Thanks, Gollum! I've now got the WET610N ordered & the EZXS55W ethernet switch. They both should be here by Friday.
The WRT610N router is in my office, hardwired to the HughesNet modem & HP Desktop running Windows XP Pro. The two new laptops (HP dv7-3078nr and HP dv8t-1000 (both running Windows 7 Home Premium 64 bit)) and the Lexmark Platinum Pro905 AIO are in my den (about 30 feet away). Right now, the dv8 (my main laptop I keep on continuosly & the Lexmark Pro905 are both here in the den, connected wirelessly to the WRT610N.
Here is the configuration of the entertainment system:
LG 50PS60 Plasma HDTV
LG LHT854 Surround Sound
LG ACC97WK-R Wireless Rear Speaker
LG BD370 BluRay DVD Player
I have DISH network with a 722K DVR
Do I need to connect the WET610N first? Then add the bridge? This is where I am afraid I am going to mess up.
Right now, everything is working GREAT.
Do you think I need to hardwire the Lexmark printer into the switch?
Could someone please advise (in very simple steps) what I need to do to get the WET610N & ethernet bridge connected?
All I want to do is be able to download NetFlix movies! I am scared that the (((HughesNet))) is going to be the problem due to their low FAP cap. Due to my location (I am 25 miles from the closest town with wireless (Verizon, Sprint, etc) offices & have already tried 3 different wireless cards here (none of which worked due to our location).
I'm beginning to think it would have been simpler to just buy the LG BD390 (wifi already installed) & put my BD370 on eBay! LOL
Any help would be greatly appreciated! TIA

AEBS and AExpress N ethernet bridge disconnects when I sleep MBP??

Hi all this is my first post but im a long time mac user having grown up in a mac house.
anyways im an it guy by profession and ive been working at this issue to no avail so I figured I might come on there and see if any of you have experienced this issue
the issue I get is that when I close/sleep my MBP it disconnects the Airport Express ethernet bridge clients
NETWORK Info
I run a small business from my home thus I have FiOS (yay 20/20) with a block of 13 static ips that i distribute via DHCP and MAC reservation to allow remote access to my network as well as keep things consistent.
I currently run cat6 from my FiOS ONT to my Airport Extreme Base Station, which i use on a strict N only in 5ghz range as my area is flooded with b/g networks but no n networks (yay again).
I recently acquired an N Airport Express to provide a wireless to ethernet bridge thus extending my network to my entertainment center (ps3 xbox etc)
(extra info: im using n here because i found that b/g limits my internet connection speeds to 7-9 mbps where as my connection is capable of 20. On my n speed network I can get my full bandwidth wirelessly, yes I know there is obviously some bandwidth and throughput loss by going wireless but not as much as a b/g network was giving me)
NETWORK SETTINGS
On my n network I distribute a range of IP addresses from my static block. I have tried a few different dhcp lease times which definitely improved my initial problem which seemed that it would log me out when the key rotated every 20 min. Currently ive bumped that up to 1 day (i know not as secure id like to set it back to 20min but it seems that when it rotates that it logs me out) and haven't had that specific issue revolving around key rotation again. ive tried the WDS, Extend a network and join a network options with no real difference in behavior when I shut my laptop and for example my GF is playing rock-band online she gets disconnected also worth noting that it seems there is an intermittent DNS issue on the express ie cant find time server even though at that time ethernet clients are able to connect and get dns response
Below is my log from my express base station when the disconnect occurs

THANKS FOR YOUR INPUT AND SUGGESTIONS

i decided to also add my log from the mbp (dont think it matters but its an early 2008 model mbp)
as you can see i put my computer to sleep at the exact same time that the airport express lost connection iI

HT1366 My iMac has been stolen. Can I find out its Ethernet ID if all I got is the Mac serial number? Will this eventually help me track it down?

Is there a way to track down a stolen imac without a findmymac app in it?
My old imac was recently stolen and all I have is the serial number. I was told that with the ethernet ID I could possibly track it down once it connects back to internet. unfortunatedlyI don`t have this ID number. All I gave is the serial number. I would like to know if I can get the ethernet ID through it?

The reason, I included the annotation that I'd upgraded my Itunes, (On my Computer) is B/C in many forums - the very first question, *HELPERS* ask, is. "Do you have the latest version of Itunes downloaded on your computer." I wanted to knock out any obvious replies.
Now- "DO YOU have any idea,"... how your UNHELPFUL remarks, do absolutely nothing but hurt others that might not have the EXPERIENCE you have? How do you expect people to know things without asking questions? Whew! RUDE!!

Ethernet Bridge and cat 5 cable to extend range?

I am in a building with wi-fi on the upper level, but I'm in the basement.
I have no means of extending the network "down" to me, but I'm trying to figure out a way for me to extend my range "up".
Does anybody know if a Wireless Ethernet Bridge (like the Belkin 802.11g Wireless Ethernet Bridge F5D7330) and a 50 foot ethernet cable could be used to pick up the wi-fi.
I'm thinking that I could possibly run the ethernet cable up the side of the building and place the wireless ethernet bridge on the roof, but I currently have no experience with a wireless bridge.
Thanks,
Luke

If you are running an Ethernet cable why not connect the Ethernet cable directly to the internet on the upper level instead of trying to detect the wireless signal?
Make sure that you use Ethernet cable which is rated for outdoor use and/or you place the cable in the proper conduit (pipe) to withstand the weather and meet any building codes.

Want to use linksys wrt300n as a ethernet bridge while the router is a time capsule.

The time capsule is connect to my modem and my wrt300 is downstairs. What I want to do I use my time capsule a my router and the wrt300 as my ethernet bridge. How do I set my wrt recieve the single from my time capsule. The wrt300. Is running dd-wrt firmware. The reason I want to do this is that I have a slingbox and it needs to be connected by Ethernet. By using the wrt as a Ethernet bridge it should work. I just need to know how.

All sounds good.. tend to use the older dd-wrt firmware to do this.. 2.4 linux kernel is far more successful than later 2.6 versions of dd-wrt.
You must manually setup wireless.. plainly only 2.4ghz is going to work.
So jump into the airport utility manual setup.. and go to the wireless page.
Depending on how old your TC is, setup a wireless name.. no spaces no special characters.. very short also is just as useful as very long. tc24 will do nicely.. Change the name of the 5ghz if it is later model to something also similarly simple.. tc5 might be nice. Call the TC a nice name again no spaces.. which it will have by default.. no special characters pure alphanumeric. TC is nice simple name.. Hard to forget really.
Set manual channels for the 2.4ghz.. this is utterly important.. repeater or bridge does not work with auto bouncing all around the place. Choose a suitable channel out of 1, 6, 11.
5ghz won't matter so you can leave that on auto if you want.
Lastly security..
Let me suggest to start leave security off. Get it setup so you know it works then come back and test the security levels.
I am not sure what to select here.. you want wpa but the dd-wrt says not wpa+wpa2..and apple do not offer straight wpa as the bridge cannot resolve which to use.. you might need to use wpa2.. but that doesn't work on some routers with repeater.. or bridge.. you are going to have a bit of trial and error here.
Make the password something nice.. you guessed it pure alphanumeric.. no spaces, no special characters.
be creative and simple.. tc24passkeynot5 .. of course use what you like.. I am giving examples to make it easier. Update the TC.
Now just do the bridge setup on the WRT300.. there are two kinds of bridge.. client bridge and wireless bridge.. there is also repeater. Client bridge has no routing .. that is what you want. But it does other things which may make you go back. Please note bridges are strange beasts.. this is going to hide clients behind the Linksys MAC address.. and it can lead to issues.
Anyway read the setup tutorial. http://www.dd-wrt.com/wiki/index.php/Client_Bridged
You will find earlier one if you use the index.. this is also useful to read. And is more extensive.
http://www.dd-wrt.com/wiki/index.php/Wireless_Bridge
There are several scattered around and I can point you to others.
When you are finished you will often need to reboot both boxes to get the bridge to establish.
Once you are done. See how it goes..
I tend to advise people that wireless bridges are flakey and will do down at the moment you want them to work. You can get EOP adapters which tend to be more reliable and use the WRT300n in wan bypass as a switch and WAP.. This is much more reliable.

Thunderbolt/Ethernet Adapter AVB/IEEE1588 Support.

Hi,
I have just seen that the Ethernet port has been removed from the MacBook Pro (retina). The Ethernet port was interestting for AVB (audio-video-bridging) development. Now that it's gone, do you know if the Thunderbolt/Ethernet Adapter supports AVB and IEEE1588?
Thanks!

Yes, it will work.
All Apple Macs with a Thunderbolt port are AVB capable.

10.9.2 knocked out Thunderbolt/Ethernet bridge
