Problems with Thunderbolt Ethernet Adapter with 10.9.1

Hi!
I made the update to 10.9.1. During the reboot after the installation I had a kernel panic. Now my thunderbolt ethernet adapter is not working any more (it does on other macs). What can I do? I have a MacBook Pro Retina early 2013.
Thanks,
Rex

I meet the same problom with thunderbolt ethernet adapter and resetting NVRAM/PRAM fixed my problem.
reset instruction and good luck

  • Thunderbolt Ethernet adapter problem

    I am a composer.I just bought a Macbook ProRetina (full upgraded) to link it as a slave to my main DAW (Logic) with Vienna Ensemble Pro 5 (http://www.vsl.co.at/en/211/497/1685/1990/1680.htm).
    The system with the new MacbookPro Retina doesn't work.
    I have contacted Vienna Instruments and it seem that the problem can be on Apple side: the Thunderbolt - Ethernet adapter.
    Any information or help to how to solve this problem?
    Thanks!

    Hi xavibcn,
    I am also a composer, and I'm trying to use Vienna Ensemble Pro over a network with a Thunderbold to Ethernet adapter. Have you been able to get it to work since you posted this? Would love to hear if you found a work-around.
    Thanks!

  • The thunderbolt ethernet adapter driver problem

    The thunderbolt ethernet adapter is not being recognized on my 2014 Macbook Air running 10.9.3. Is there a driver for it?  MacBook Air, Mac OS X (10.9.2)

    That's because there's no thunderbolt port on the 2010 MBair.  You need to buy the USB ethernet adapter.

  • Windows 7 64bit on bootcamp doesn't recognize the thunderbolt-ethernet adapter

    in my new macbook pro retina I've a problem on window 7 64bit (bootcamp 4.0). the OS doesn't recognize the thunderbolt-ethernet adapter..

    The thunderbolt ethernet adapter works without issue on my rMBP with Windows 7. Did you download and install the Windows Support software? Did you refer to the Windows help regarding networking? Did you try a different adapter? What happens when you try to use Ethernet networking?

  • Thunderbolt ethernet adapter causing buzz within MBP.

    I've noticed something very weird lately with my retina MBP. Whenever I'm loading largish (> 1mb images) files in the browser, my laptop emits a noise that sounds like there's a tiny little buzzer somewhere inside the laptop. It lasts as long as the file is loading onto the page or downloading in the background. I've been able to reduce the problem down to only occurring when I'm plugged in using a thunderbolt ethernet adapter. On power, off power, connected to external display or not, the noise is present. I would really like to stay connected to ethernet, but I have no idea where to begin fixing this very weird problem.

    I bought a new adapter but this one doesn't work too! That's €29 well spent
    So anybody got any clue what to do? It shows up in the system info, but there is no thunderbolt ethernet interface available in network settings...

  • Thunderbolt  ethernet adapter

    Hi,
    Using the wired thunderbolt ethernet adapter my network works for about a minute after the adapter is plugged in then stops working with the cable showing as unplugged in network settings.  The only way to reconnect is to pull the adapter and re-insert it.
    As far as I can tell all software and firmware is up to date.
    Is this likely to be a faulty adapter or am I missing some other settings?
    thanks,
    Andy

  • 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.

  • I have an airbook, 10.7.4 LION, thunderbolt ethernet adapter and when trying to install 1.2.1 thunderbolt upgrade it says "this software not supported on this system"? Any advice on how to get the adapter to work?

    Welcome to Apple Support Communities
    If you purchased the computer before 2010, your computer hasn't got Thunderbolt, so you can't use it

  • Will I see speed increase with thunderbolt/Ether adapter?

    I have a 2012 Mac Pro connected to my network with Ethernet cable: MP > router > cable modem. Cable and modem are 10/100/1000.
    Apple makes a Thunderbolt / Gigabit Ethernet adapter (http://store.apple.com/us/product/MD463ZM/A/thunderbolt-to-gigabit-ethernet-adap ter).
    Anyone know if I might see any noticeable speed increase to the Internet switching from my Ethernet port out, to Thunderbolt port out using this adapter?
    My broadband is 30 Mbps down, 5 Mbps Up, btw.
    Thx!

    Most devices that are serving as the Ethernet Switches are only 100BaseT capable. That is why I said "choose" to go up to that speed. (Some folks, like me, have to go out and buy Gigabit-capable switches.) Apple Routers (they don't make Just a Switch, but you can configure a Base Station as a Switch) are Gigabit-capable.
    My modem, router Ethernet ports are both Gigabit capable and I'm using the best wire I could get Cat 6.
    The longest cable is 50 feet.
    If all 8 conductors are crimped into the connectors with all 8 wires in use, you are all set. Cables that use only two pairs of wires instead of four pairs will not work.
    Check by using Network Utility.app to see if you are already using Gigabit Ethernet speeds. If you ARE, then you should also configure Jumbo frames. If not, you can manually configure it to Gigabit speeds, Full duplex with flow Control, but if it cannot, for same reason, connect at that speed it will not fall back, it will fail to connect.

  • Retina macbook pro with thunderbolt ethernet adaptor drops internet connection on open apps after waking

    I recently started using a thunderbolt ethernet adaptor and every time my comuter wakes from sleep, all the apps that were open no longer use the internet connection.  I have to restart each one of them for them to be able to use the present internet connection. any ideas?

    So I've noticed similar behaviour on my Macbook Air. It's a slightly different set of kit, since it's connected to a Belkin Thunderbolt Express Dock (http://www.belkin.com/uk/p/P-F4U055/). I'm on my second one of these because first one went back because it kept on dropping the internet connection (sounds familiar?) - and it *might* have been occurring when waking the system from sleep (I didn't make a mental note).
    Anyway the replacement was working perfectly, until today - when it's started to drop it's internet connection again, and this time I'm pretty certain that it's related to waking from sleep. The main difference now is that I *just* upgraded to Mavericks, and I wonder if the sleep problem has reared its ugly head again in the latest version of MacOS?
    All in all I have to say I'm pretty disappointed with the reliability of thunderbolt & the Belkin Dock thingie. Although it should be said that a single lead from my Macbook Air to the Express Dock is simultaneously carrying: video (1920x1200), Firewire800, 3xUSB3, gigabit ethernet and sound, so I'm not that surprised this technology is prone to the odd glitch, and the cables get really warm too!
    It would be great to have some solid information from Apple/Belkin about this.
    Cheers, Jon

  • Can you determine link status with USB Ethernet adapter?

    I'm wanting to replace an old G4 PowerBook with a 11" MacBookAir. I install networks, and I often need to determine link status of an Ethernet connection. With the built-in Ethernet port on most Macs, you can check the Network Status to see if there is link on an Ethernet connection (either the green or yellow status signs).
    If I am using the Apple USB Ethernet adapter, do I get similar feedback from the Network preference panel? If not, perhaps a terminal command that would do the same?

    Yes - the Network Panel under System Preferences works the same as with a regular Mac, showing USB Ethernet status (connected, disconnected, etc) and with the updated connected IP address, etc.

  • WRT54GS CONNECTION TO MODEM THROUGH USB CABLE WITH AN ETHERNET ADAPTER

    The ethernet port on my motorola surfboard modem is damaged but the usb port is fine.  I am attempting to connect my WRT54GS (ver 6) router to the modem via a usb cable with a male ethernet adapter.  Unfortunately it does not appear that the router is able to accept such an input due to driver or firmware issues.  The modem requires me to set up my pc with another driver specifically for the usb connection when i am connected directly.  Any suggestions?

    Get a new modem, The USB is not meant for that it's meant for wireless network storage.
    GoodLuck

  • Do you turn off wi-fi when using Thunderbolt ethernet adapter?

    I set-up the Thunderbolt to ethernet adapter for my Mac Book Pro Retina. Easy set-up.
    It shows wi-fi and thunderbolt both on under Network. Do I need to turn off the Wi-Fi connection if using the Thunderbolt adapter? My internet didn't connect on my Windows laptop this morning wireless and I reset the Cable and router so it may not have had anything to do with it.
    Thanks.

    I turned wi-fi off on my Mac Book Pro and left just thunderbolt ethernet connected and it is working fine. It must have been a glitch in the router or modem that messed it up this morning on my Windows laptop as that is running wireless.

  • Thunderbolt Ethernet adapter not connecting on MacBook Pro Retina

    I recently purchased the Thunderbolt to Ethernet Adapter to connect to my 13in MacBook Pro Retina Late 2012 (Mountain Lion 10.8.2) to a hardwired internet connection for faster downloads. However, when I connect the ethernet cord to the adapter nothing happens and only the wifi connection is identified.
    Ethernet or Thunderbolt Ethernet are not an option in the System Preference > Network. Also, either connection are options when trying to add a network interface ( System Preferences > Network > + > Interface).
    I have tried several fixes like Resetting PRAM or Removing Network Preferences File. The NetworkInferences.plist and Preferences.plist files did get recreated after reboot, but only the WIFI interface shows up.

    I am sure the Thunderbolt ports are functional since I am able to connect my display using Mini DisplayPort to DVI Adapter
    Could I have corrupted the Network Preference File or is could the Thunderbolt to Ethernet Adapter damaged?
    Please help.

    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.
