    Nearly useless

    • Written by from Brooklyn

    This item is not plug-and-play under Windows 7, nor Windows 8. You have to have it connected BEFORE you start Windows on your Mac.
    Quality of service under MacOS is questionable, too.

    I am reverting to USB adapter.

    First Time Mac User

    • Written by from Bittern

    As a mobile technician I needed to buy one of these adapters to cater for one of our sites that does not have a wireless access point. As a first time Mac user, I forgot that the new Macbook Pro doesn't have an RJ-45 port in my excitement when buying the unit. The adapter works perfectly and I couldn't be happier.

    I visited several major retail chains looking for this adapter and eventually gave up - it's normally a special order item and the big department stores do not seem to stock it. I ordered the adapter via the apple store app on my phone, midday on a Monday, and it arrived midday on a Tuesday from Sydney to Melbourne. Great product and mind bogglingly quick interstate delivery.

    This adapter takes more battery juice than Wifi

    • Written by from Davao

    Is everyone experiencing this? I've tried testing both wifi and thunderbolt adapter. My conclusion was wrong.

    Using Battery Health app I got this:
    The watts usage after 1 minute:

    Wifi ~ 9.34 Watts
    Thunderbolt to Gigabit Ethernet ~ 12.31 Watts

    I'm using ML 10.8.1 and MacBook Pro Retina.

    It's disappointing because I bought this to minimize battery usage in the first place.

    works great (adds the port that should have been there)

    • Written by from Laguna Niguel

    I used with a MacBook Pro (Retina).

    I connected with a Cat 6 cable directly to a Mac Pro (2008) ethernet port. Using the Finder, can transfer files at about 100 MB/s (as seen in Activity Monitor during the transfer). This is way faster than the 7 MB/s I get when doing the same thing over the Airport Extreme network (WiFi 802.11n).

    Pros: works great. Way faster than WiFi. Adds a port I think should have been there (yes, even in 2012).
    Cons: Uses up a Thunderbolt port (no daisy-chaining this puppy). Is an additional thing to carry around.

    Piece of junk

    • Written by from PALMERSTON

    What a piece of junk this is. It used to be so easy to connect my ReadyNAS NV+ via the ethernet cable to my Macbook. Now on the new Retina Macbook Pro, there is no Ethernet port anymore so I have to purchase and use this piece of useless gear. It just does not connect reliably with the ReadyNAS and I have to unplug and plug back in for both ethernet cards to negotiate the IP address. I don't care if there is a logical reason for why this occurs. All I know as the customer is that something that was previously easy and reliable is now patchy and annoying. Apple, please fix this with a firmware or driver update for the Thunderbolt to Ethernet adapter. Please!

    Windows 7 Problems

    • Written by from Colorado Springs

    I have a Macbook Air that I installed bootcamp on and primarily use Windows 7 64bit for many reasons (one being my job). I purchased the Thunderbolt to Gigabit Ethernet Adapter and assumed it worked flawlessly with Windows 7 and the Mac OS X. First I would like to clarify for the Mac OS X side, it works great, wish I could say the same for Windows. Here are the list of issues with Windows 7 and the Thunderbolt Ethernet adapter.

    1) If the computer is already turned on and booted into Windows, Windows will not detect new hardware, even if you search for new hardware under device manager. To get around this issue, you need to either plug in the adapter then reboot the computer into Windows or shut down the computer then plug in the adapter and then turn it on and boot into Windows.

    2) Windows 7 does not automatically find the driver, even if connected to the internet. For me this wasn't a problem as I am in the IT industry and was able to find the drivers in a short time, but for the average user, this can be problematic. Hopefully Apple will include the driver in a future patch for the Windows 7 Bootcamp Installer. I downloaded the driver directly from Broadcom's website (NetXtreme Desktop/Mobile drivers)

    3) Having the Thunderbolt to Gigabit Ethernet adapter plugged into the computer disables sleep mode. Even if you plug in the adapter, use it then unplug it, the only way to re-enable the option to use sleep mode is to reboot the computer. Hopefully Broadcom will write a new driver that is S3 Sleep compatible.

    Hopefully this issue will be addressed shortly. I most likely will be returning this item and getting the USB to ethernet adapter which I'm not excited about since it has slower speeds then even 100Mbps due to the limitation of USB 2.0.

    Does not work for me..

    • Written by from Eatontown

    I purchased this adapter for my MacBook Air, where i also have Windows XP installed through VirtualBox. thing is, Windows doesn't recognize this device at all. I did some searching and found out that some Broadcom driver works, but only on Windows Vista & 7. I need the adapter so I can use the ethernet port to connect to Extron and Crestron Devices such as MLC's and wall controls for miscelaneous high-end media systems. Those programming apps come only for Windows. and the Adapter doesn't work in Windows, which makes me go back and return the item. Unless anybody has some suggestions how to make this work.

    Now I can have ethernet port when my wifi is not working or when I am in hotels with wired connection only. At first it did not work, gave it a few minutes, plugged it again and then it is connected and ready to go! I have a Macbook Air 2011.

    Works great, what else is there to say?

    • Written by from Fort Macleod

    Works as advertised, gives the MBA a Ethernet port for when you are at a hotel/friends house or whatever the occasion may be. Make sure you have the Thunderbolt 1.2.1 update installed or else this won't work.

    Loses 1 star because it doesn't work in Windows (Boot Camp) yet.

    2011 MacBook Air

    • Written by from Mill Creek

    At first I didn't think it worked, but I looked in the Systems Network box and noticed that there was no Thunderbolt Ethernet entry. Checked for software updates and there was the Thunderbolt driver update and after a restart, it works perfectly.

    Just like you'd expect.

    Now for Boot Camp, i have 4.0 installed and I can't get this working. I'm assuming there's a BC 4.1 in the works?

    This is a case of a product that should have been released with Thunderbolt. Using USB 2 to Ethernet was never a good idea!

    This product, however late is great! Update the driver, plug it in and go. Actually go very fast!

    Thanks Apple!

    Insane fast

    • Written by from Bronx

    Thunderbolt has been around for so long, and only now are some accessories available. I own the 2011 13" Air, and I have been waiting for this for a long time. Finally I can free up the slow USB port, and use the insane fast Thunderbolt IO for gig ethernet.

    I downloaded the new update and applied it. Fast reboot and we were up and running.

    Crazy fast. Copying files from my NAS to my laptop, i saw transfer speeds of up to 100MB/sec. I use this mainly for work events, where we move large files a lot.

    The adapter does run a bit warm, but I guess that is normal. If you need to plug into wired gig networks, then you MUST have this.
