      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.

      Stops working

      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 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.

      POOR POOR POOR Product Listing - Does not fit 2016 MB Pro.

      Waste of time, money, and effort. Called support and it took longer to set up the incident then to get an answer of how it fits into the MB. BY THE WAY the pic Waste of time, money, and effort. Called support and it took longer to set up the incident then to get an answer of how it fits into the MB. BY THE WAY the picture of the product only has one view and the end is hidden. Lets all spend time sending the product back to apple and this could of been fixed. Just stupid.

      stupid dongles

      Apple gives you dongles with the idea, you'll spend more time getting replacements.. Although i have replaced my power adapters less, if there is one thing i Apple gives you dongles with the idea, you'll spend more time getting replacements.. Although i have replaced my power adapters less, if there is one thing i replace constantly are Thunderbolt to Gigabit adapters.. :P Gone though 5 in two months.. Mostly. there is noting worse than coping heaps of smaller files, total 40Gig which takes several hours, but then you loose connection at the end of the copy. Unhappy customer.but Apple's got us.... if you have Thunderbolt, you must buy dongles... Apple is smart at how they force users into this position.

      Good device but where's the TB3 version?

      Highly reliable Ethernet adapter that does not draw a lot of power. As superior to USB versions as it is, it's infuriating that nobody, not even Apple, has both Highly reliable Ethernet adapter that does not draw a lot of power. As superior to USB versions as it is, it's infuriating that nobody, not even Apple, has bothered to bring it out in a Thunderbolt 3 version, forcing people to use inferior models that use a USB controller and draw a lot of power including precious battery power and overheat. Very annoying being forced to choose between a USB power hog and daisy chaining this thing on a TB3-2 adapter when away from an appropriate dock or adequate wireless, but at least the daisy chaining is also reliable as long as nothing pulls out of the connection.

    • Can I use this cable to hook up a Time Capsule to my iMac?

      Best Answer:

      This adapter is not necessary to connect your iMac to your Time Capsule for internet access and for This adapter is not necessary to connect your iMac to your Time Capsule for internet access and for your Time Machine backups. Time Capsule and iMac can be connected via Wifi. In almost all cases, though, using this adapter with a decent ethernet cable (I recommend at least a Cat 5e ethernet cable) connected hard-wired to your Time Capsule will not only improve your internet speed on your iMac, but also your Time Machine backup speed. The actual improvement in speed of these things will depend on your current internet speed and distance between the iMac and Time Capsule along with other possible interferences. In most cases, though, I would say the average user would notice a slight increase in performance, and the power user to notice a significant performance increase. If you deal with backup up many large files and are a heavy-bandwidth user, I woul definitely recommend using this adapter with either a Cat 5e or Cat 6 cable.

    • Is this Thunderbolt 3?

      Answer

      No, it's Thunderbolt 2. In order to use it with a Thunderbolt 3 port, you'd need a Thunderbolt-3-to No, it's Thunderbolt 2. In order to use it with a Thunderbolt 3 port, you'd need a Thunderbolt-3-to-Thunderbolt-2 adapter. There's one on the store... search for "Thunderbolt 3 USB-C to Thunderbolt 2 Adapter" As unwieldy (and expensive) as chaining two adapters together may seem, at the time of this writing, it's probably the most reliable way to have a highly-portable, high-performance, reliable Ethernet connection. Any other USB-C dongle-style adapter available today will add its Ethernet port via the Type-C port's USB 3 channel, not the Thunderbolt channel. This makes the adapter much more prone to issues with reliability, driver compatibility, heat, and CPU usage. If something less portable is an option for you, I'd recommend using a Thunderbolt 3 dock to add an Ethernet port, since it would use the Thunderbolt channel, giving you better reliability and performance. I've used one by CalDigit with no issues, and Apple sells one by Belkin here on the store... search for "Belkin Thunderbolt 3 Express Dock HD"
