    Bought it at Bestbuy. And it stopped working after 20 days.

    The size could be smaller. And it quality could be more reliable.

    JUST DOES NOT WORK...

    • Written by from NEW YORK

    Bought this to connect ethernet in my dorm on my Macbook with Retina Display. Since August, I have not been able to get any internet access. Why??? I don't get it! Never experienced such disappointment with an Apple product!

    Doesn't work - get USB 3.0 to Gigabit instead

    • Written by from Poway

    Got one from apple store, had trouble getting it to work with Windows 7 or Windows 8 (worked on Mac side fine though). Since i use bootcamp a lot and needed a full gigabit speed - ended up returning and buying a USB 3.0 one from usb3gigabit.com. This one worked on mac and on Windows without any issues plus it left my thunderbolt usable for the display or storage.

    Do not use if you want this to work with WIndows 7

    • Written by from marina del rey

    I dual boot my MBP to Windows 7 in order to do work on it. Although I can get this adapter to work in Windows 7, there are two major drawbacks. First is that the dongle has to be attached to the MBP AT BOOT or it will not see it. You cannot plug it in after it has booted and expect Windows to see it. Second is that once you do have it working, the laptop CANT GO TO SLEEP! It goes into hibernation mode, which is a deal-breaker. If you need a network adapter that'll work with Windows 7, this is NOT your product. I am very disappointed with Apple about this.

    Very fast but.... (rMBP)

    • Written by from Uckfield

    It is a very fast adapter, bought it for my rMBP to use at uni. the issue is that it falls out VERY easily, which is somewhat of an issue for me. when working at a desk its fine, but at other times it gets knocked even just a little and it disconnects and takes a while to reconnect. This is annoying!

    Perfect for Macbook Pro Retina

    • Written by from Singapore

    It was instantly recognized as it was plugged in.
    The speed it gave was very fast and it is portable to carry.

    But if you have thunderbolt display you might not need this except under mobile environment.

    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.

    Wicked Fast, but needs to be on power!

    • Written by from Airdrie

    I thought I had a faulty one, as on my MacBook Air it didn't work - it randomly came up as a thunderbolt device, but no ethernet, or not at all.

    I then tried it on power, and "pop" - it just worked, as expected... and it is very, very fast. copying files onto the Air with it's SSD I was getting a nice solid 45Mb a second.

    This is now part of my carry around kit for the laptop - excellent when you need a little more "oomph" than you can get with the Wireless.
