    Periodically stops working physical connection loose

    • Written by Thomas S from Clarksville

    This dongle stuff is not reliable over time. On my 2015 MBP, the lightning connector for this adapter is loose in both ports. I will be running web meetings and if my laptop shifts or I bump the cable, the network disconnects, killing my meeting. It's really frustrating to have spent $2,000, then $30 for this connector and have unreliable Internet. I don't know if the flaw is with the adapter or laptop ports, or both. Just ridiculous to have this problem. I was better off with tech in the 1990s, then I plugged in network cable and it never failed.

    works fine but it's a shame you need one

    • Written by Oliver G from Blandford Forum

    The adapter works fine connected to my macbook pro with retina display, and my macbook air, in that it allows you to plug your ethernet cable into the computer.

    It's a shame however that the thunderbolt plug and socket are not nearly as sturdy as ethernet, and come out far too easily, which is very frustrating.

    But the real issue is that the computer doesn't come with an ethernet port. I can understand in the case of the macbook air that they are all about thinness, and ethernet is fractionally thicker than thunderbolt. But a MacBook Pro should not be without ethernet. Professionals using these machines rely on ethernet all the time for transferring large amounts of data. The photography, film and music industries all use ethernet to transfer data to and from computers and servers. And carrying around a flimsy adapter that falls out of it's socket with a gentle nudge just isn't a viable option. But until Apple changes their "pro" design, I guess we're stuck with these silly, flimsy and overpriced things.

    Stops working

    • Written by OSCAR C from Chicago

    I had it for a 2-3 years. I used it 30-40 times and stopped working. This is the second connector from Apple that behaves this way. I used to have one to get an HDMI connection (before it became standard in the MacBookPro), which I used 10 times before it quit. No buying these expensive gadgets from Apple anymore.

    This doesn't work in El Capitan when using high speed 1000BaseT gigabit eth

    • Written by Enrique C from Dublin 6

    In a Macbook pro Retina Late 2013 with OSX 10.11.4, it doesn't support gigabit ethernet. It works fine with 100baseTX but it doesn't work with 1000BaseT.

    Very fast but.... (rMBP)

    • Written by Ben C 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!

    Product does not work as described

    • Written by John M P from Portola Valley

    I have two of these adapters. After updating my MacBook Pro to Sierra, I can no longer get either adapter to connect to my GigE LAN. In System Preferences > Network, the Thunderbolt-Ethernet service indicates that a cable is unplugged. However, in About this Mac, the adapter shows up as plugged in. I've tested all connections, applied every update and tried every fix out there. Doesn't matter, no connection to GigE LAN.

    Before this failure, I could transfer large files from my MBPr to my LAN at GigE speeds. Now, the MBPr can only access my LAN at WiFi speeds - less than 10% as fast. PITA.

    This is a known issue (do a search) affecting many. Apple hasn't fixed it.

    Apple killed functionality of this adapter. Don't buy it. It will not work for you.

    Poor Design

    • Written by SEAN K from La Canada

    Understandably, it does function properly. However with my circumstances, I'm always moving around with my Macbook. The wifi signal in my facilities aren't very strong, so I am to resort to this method. With that said, the adaptor itself always loses connection very easily when my MacBook moves but an inch. It would have been a very smart idea for Apple to have an integrated clip on the thunderbolt end of the adaptor, and on the MacBook itself 'inserts' for the clip to latch itself. When wireless internet fails, this minor flaw is clearly an annoyance, especially when this product is overlooked due to convenience and short term design.

    works great! for a while

    • Written by Stephanie O from Franklin

    I got the thunderbolt adapter for my Macbook air because the place I was going to be at for a few months didn't have wifi. For the first three months of my stay I had absolutely zero trouble with it, but this past month it will occassionally disconnect but then a few minutes later will reconnect. It's been really iffy recently, and I've been a little bit concerned about plugging it into my computer. Hopefully I won't need it for too much longer, I'm not sure if it is meant to last more than a few months!

    I've had my adapter for about two years with limited use. It sporadically drops my internet connection, which is not great while taking online exams or gaming. I'm not satisfied with the longevity of this product.

    same as others have reported, it gets unreliable and then stops working altogether. I can't think of any reason a part like this should "wear out"

    Does not Plug into 2017 MacBook Pro

    • Written by Kellar W from Olney

    I've now spent $200+ dollars on hubs, connectors, and extension cords to enable my uber expensive MacBook Pro to operate like a normal docked laptop. This accessory allows the ethernet to plug into it, but does not plug into any of the Apple designed Thunderbolt ports - the only ports available with the new laptop. Ports that make all connections stick out, just begging to get jammed sideways.

    You are better than this Apple.

    Constant disconnects very frustrating

    • Written by Brian Z from SAN FRANCISCO

    Bought the highest end MacBook Pro on the market at the time and from day one, this adapter has had a major engineering flaw, at least with my MacBook Pro Mid 2015 15inch. Any slightest movement or jiggle of the adapter base at the socket of the Mac, even the movement from pressing palms to the keyboard is enough to cause an internet disconnect. I can replicate it 100% of the time, and my testing has insured it's not the ethernet cable going into he adapter. I can literally watch my connection disconnect and reconnect in the Network Preferences as I touch the plug. I know it's not a defect with my specific adapter either, but rather a design flaw (the plug on the adapter is simply too loose for the female port on the MacBook Pro). I have swapped my specific adapter with other people's identical ones and also have the same effect of connection loss with any movement. I have been an Apple fanboy since my Mac Plus and this has been my first disappointment. Really wish they would have just left an ethernet port on the machine.

    Another observation - this might go under reported due to wireless Wi/Fi, as it will eventually just switch over from the dead ethernet to Wi/Fi and many people might not even notice it disconnected at all, unless they're on an application that required a constant connection. For example, if they were just web browsing, it might not be noticed.

    Waste of money

    • Written by Caroline G from Deptford

    I had to go buy this after an apple employee told me nothing but the thunderbolt would work as an ethernet adapter on the mac. Under system report, the thunderbolt shows up as connected but under network it won't work. I spent over an hour on the phone with tech support trying to trouble shoot just to have her say 'I don't know what else you want me to do' and hangup. Wasted my money because this doesn't work and I still dont have internet access.

    Works great at gigabit speeds on my 15" Late 2013 MacBook Pro w/ El Capitan

    • Written by Krishen G from Sarasota

    Just saw a review that said this adaptor doesn't work at gigabit speeds on OS X El Capitan 10.11.4.

    Well, I don't have 10.11.4 anymore, I've got 10.11.6, however, at no point have I ever noticed my network performance slow down with it. And I would notice, because I am frequently moving around 1+ GB files around our company network.

    I've had nothing but good experiences with this adapter. High-performance, works just as though the port is built into the Mac.

    Poor performance

    • Written by Bijay S from Kolkata

    I bought MBP along with Thunderbolt to Gigabit Ethernet Adapter. For some reason, either with the adapter or the port or both, the internet connection keeps dropping. When the connection is dropped, i attach the ethernet cable to Del laptop, it works just fine. So the problem appears to be with the adapter/port. The adapter also get very warm, which is normal as told by Apple staff. Net conclusion: very frustrating to lose internet in the middle of work.
