      Periodically stops working physical connection loose

      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 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

      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. 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.

      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 a 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!

      The dongle actually works okay in a physical sense and isn't annoying or anything but I use it every single day for work in a secure environment which requires The dongle actually works okay in a physical sense and isn't annoying or anything but I use it every single day for work in a secure environment which requires ethernet connectivity. If I lost my network access while I'm working it limits my productivity and this happens at least half a dozen times a day whenever anyone knocks the ethernet cable or adapter. I just wish it worked as well as an ethernet cable, there is truly no substitute for time tested solutions.

      Waste of money

      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 thunderb 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.

      Ease of Use & Reliable Virtual NIC Teaming

      I have one of this 'Thunderbolt to Gigabit Ethernet' adapter for the last 1+ to 2 years. It has served me well and works seamlessly through the update of macOS I have one of this 'Thunderbolt to Gigabit Ethernet' adapter for the last 1+ to 2 years. It has served me well and works seamlessly through the update of macOS from Mountain Lion (I think) to Sierra to now High Sierra on an iMac. I vividly remembered there was one or two minor bugs back with Sierra Public Betas but it was sorted out at official release. The 'Thunderbolt to Gigabit Ethernet' adapter is easy to install (just plug in and it works) and even easy to configure virtual NIC teaming to allow redundancy in connectivity. Fail-over works seamlessly too and maintain connectivity to the network when the iMac onboard NIC's connectivity is down (e.g. primary network switch's firmware update and reboot). I am not able to recall what is the typical throughput of this 'Thunderbolt to Gigabit Ethernet' adapter. I vividly recall it is not the most fantastic throughput but given it is afterall an external adapter, some overhead loss is expectable. No compatibility issues experienced which may indicate the chipset used in this adapter is fairly compatible with that used in the network switches I have (Ubiquiti Edge Switches).
