    Stopped working

    This adapter worked fine for a month on a Macbook Retina and then stopped working. Just died. Waste of money and lots of aggravation.

    Excellent! Allows for two ethernet ports on a Mac Mini running Mac OS X!

    I needed to set up my Mac Mini as a file server, connecting to an iSCSI RAID drive made by Drobo (a DroboPro to be precise). To do so, I needed to add another ethernet port to my Mini, so that I could have one port for connecting the Drobo, and one for talking to the network. To address this issue, I looked in to the Thunderbolt Ethernet adaptor from Apple. Unfortunately, no information that I could find would confirm that these adaptors would work with anything other than MacBook Airs. As such, I decided to take a chance, try it out on my Mini, and if it worked great, if not, I would return it.

    I purchased it and waited for it to arrive. Once it arrived, I immediately plugged it in to the Mini. Unfortunately, nothing changed in the Network Interface list in Network System Preferences...Darn - maybe it isn't supported....I thought. It also seemed very loose when plugged in to the port, much looser than a mini-display port adaptor. That seemed strange due to the fact that they were the same size plug.

    For the longest time, I couldn't realize why the Mac Mini would not recognize the presence of the adapter, while when used on my MacBook Pro it was recognized perfectly. Eventually, I placed a light back in the networking closet and realized that the adaptor wasn't pushed in all the way! Once I pushed in the adaptor all the way, it worked perfectly on my Mac Mini running Mac OS X 10.8. It was recognized instantly and the thunderbolt ethernet port automatically appeared in the network system preferences.

    I now have a connection to the Drobo RAID array that is at least 3x faster than before. This is a great little adaptor for use in Mac Mini computers running OS X.

    Highly Recommended, just make sure to push it in all the way, with a little more force than you might think is needed.

    From Leatherneck Afghanistan

    I just purchased the Thunderbolt to Gigabit Ethernet Adapter and it works great with my MBA - plug and play. Money well invested.

    Great Speeds

    At first I was hesitant based on the reviews but now that I've been using it for a month I couldn't be more happy. Backing up my 13"MBPr to a Network Attached Storage (NAS) device are so incredible fast compared to wifi. I do have a gigabit network setup. Moving large files or completed back-ups that used to take hours are now less than an hour.

    plug and play

    Works on 2012 Macbook Air and mid 2011 iMac (EMC#2428) both with Mountain Lion (10.8.2). Plug and play, no drivers.

    Does NOT work with Wireshark! Wireshark does not recognize the thunderbolt ethernet adapter. Hence the 4 star rating. If you don't need wireshark or packet capture, then it's great. I prefer this over the USB to Fast Ethernet adapter because its faster (1000Mbps versus the 10/100 of the USB model), and it doesn't take up a precious USB port (since the Macbook Air only has 2 USB ports).

    Worked for about a month

    Speed was fine. I used it constantly because we have no wifi here, and after the first time I unplugged it, I got a DNS error. Some random rebooting and unplugging fixed it, but after unplugging it a second time the same thing happened and nothing I've tried has fixed it. Looking around the internet, other people with mid-2012 macbook airs seem to be having the same problem with it. Fix this apple!

    Energy Sucker

    I just bought a 2012 macbook air recently and I bought the thunderbolt to ethernet adaptor since my home network is hardwired. At first I couldn't get it to work but after some updates for OS X Mountain Lion it was working perfectly. I did notice my battery dying super fast when I use it.

    To everyone complaining about this not working in Windows... That's obvious. Apple builds its hardware to work with its own OS not windows. If you want to use accessories with Windows than make sure they are compatible with windows.

    Works well. Minor flaw.

    The cable works very well, although it very easily disconnects itself from the computer.
    Any slight bump and the connection is lost... which isn't very pleasant when uploading files and getting the error: "file transfer failed".
    There should be a little clip to keep it in place because it's very irritating to have it disconnect every few seconds.

    It works, but

    It works out of the box on my MacBook Air 13' - 2012, but sometimes it will hang the Mac when hot-plugged.

    Requires OS X update. No instructions for Win7.

    I couldn't get mine to work until I downloaded the update for OS X.

    In boot camp (windows 7) it's not detected at all. The one thread I found explains how to load the drivers but they are buggy - BSOD.

    Only buy this if you REALLY need gig speeds in OS X and have some understanding of how to load drivers in Win7.

    Stopped working after 20 days.

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

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

    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

    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

    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)

    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

    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

    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

    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.
