  • Overview

    The Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter lets you connect Thunderbolt and Thunderbolt 2 devices — such as external hard drives and Thunderbolt docks — to any of the Thunderbolt 3 (USB-C) ports on your MacBook Pro.

    As a bidirectional adapter, it can also connect new Thunderbolt 3 devices to a Mac with a Thunderbolt or Thunderbolt 2 port and macOS Sierra.

    In addition, it can be used to connect Thunderbolt-enabled displays — such as the Apple Thunderbolt Display and LG Thunderbolt 2 displays — to any of the Thunderbolt 3 (USB-C) ports on your MacBook Pro. However, using this adapter with an Apple Thunderbolt Display requires a power source, because the display does not provide power through the adapter.

    Note: This adapter does not support DisplayPort displays like the Apple LED Cinema Display or third-party DisplayPort and Mini DisplayPort displays. For more information, visit the Apple Support page for the Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter.

      Problems with chained displays, waking up from sleep / restarts

      This adapter does NOT duplicate the functionality of the Thunderbolt ports on MacBook Airs and legacy MacBook Pros when daisy-chaining accessories together. For This adapter does NOT duplicate the functionality of the Thunderbolt ports on MacBook Airs and legacy MacBook Pros when daisy-chaining accessories together. For example, I have a external hard drive chained to a DisplayPort monitor. On my old MacBook Air, the two would be recognized right away. I could wake up my computer from sleep (clamshell shut, hooked to external monitor and keyboard / mouse) and the hard drive would spin up and the monitor would turn on. With my new MacBook Pro and this adapter, however, waking up the computer from sleep, with the exact same connections, and the hard drive turns on but the monitor doesn't. If I open the lid of the laptop, then magically both displays will start working. Similarly, if I try to restart the computer in clamshell mode when the monitor is recognized and working (again, daisy-chained to the hard drive), upon being restart the monitor isn't recognized. If I try to open the lid of the laptop, then the MacBook Pro's own display won't even turn on, making me have to restart it. In short, this adapter doesn't work unless you have the most basic Thunderbolt setup. Don't expect anything daisy-chained to work. Don't expect restarts to work. Don't expect waking up from sleep to have your plugged-in accessories to work the same as when you put your computer to sleep.

      Thunderbolt Display

      Just brought this home to use on my new late-2016 MacBook Pro 13. This adaptor allowed me to use my Thunderbolt display. Very happy!

      I feel so screwed over.

      Of all the overpriced Apple cables that I own (and I have A LOT of them), this is the most useless one. It doesn't work if both devices you're trying to connect Of all the overpriced Apple cables that I own (and I have A LOT of them), this is the most useless one. It doesn't work if both devices you're trying to connect don't have their own power source. Which means it won't work on most external harddrives. Since that's the only thing I needed it for, I'm feel cheated. There should at least be a big red sticker on the package stating how this thing doesn't provide power. I can't believe I paid 55 euro's for this. I know it's been a long long time since Apple actually cared about its customers. But this a whole new level of disrespecting people. It makes me want to quite Apple products altogether.

      Adapters are garbage and should be pulled/discontinued

      I have x2 of these, one purchased last week and another purchased a year ago. Neither of these will connect my G-RAID storage device to my mac pro 2013 (Sierra I have x2 of these, one purchased last week and another purchased a year ago. Neither of these will connect my G-RAID storage device to my mac pro 2013 (Sierra). The USB-C connects it fine to my macbook pro, the USB connects to both computers, but using these adapters to go from USB-C/Thunderbolt 3 to Thunderbolt 2 does not work. Garbage! I decided to purchase a thunderbolt 3 device over a thunderbolt 2 because of the existence of this adapter. Thanks apple!! My loyalty was already waining... I can't keep up the charade any longer. You guys have really abandoned any common sense here.

      DisplayPort Support

      I see a lot of negative reviews about this product not supporting DisplayPort monitors. It states very clearly in the product description that it supports Thund I see a lot of negative reviews about this product not supporting DisplayPort monitors. It states very clearly in the product description that it supports Thunderbold displays but NOT DisplayPort monitors. It does what it's supposed to do very well. People could save themselves being disappointed (and this applies to any product) by "carefully" reading the product's description and doing a bit of research before purchasing. The vast majority of the negative reviews I've read are totally undeserved because people didn't bother to do their homework first...just saying!!
