  • 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 or later.

    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!

      DOES NOT WORK WITH ADAPTERS

      I bought two of these because I have a Thunderbolt 2 to DVI adapter and Thunderbolt 2 to HDMI adapter. This does not work with either of those. I wish I read th I bought two of these because I have a Thunderbolt 2 to DVI adapter and Thunderbolt 2 to HDMI adapter. This does not work with either of those. I wish I read these reviews first. I could have saved time and bought a 3rd party Thunderbolt 3 to DVI adapter. 0 stars.

      Didn't work for Drobo or for Decklink

      Bought two adapters. One to use with my Blackmagic Design Decklink to display on an external monitor while using Davinci Resolve. I wasn't sure if this would Bought two adapters. One to use with my Blackmagic Design Decklink to display on an external monitor while using Davinci Resolve. I wasn't sure if this would work because I couldn't find any documentation about it specifically, but it did say it should work with displays. The software doesn't recognize it. Second adapter was to connect my Drobo 5D to my new iMac Pro. I assumed this would work because I found documentation that it should work with external hard drives. Also FAIL! Looks like I may have to do some more costly hardware upgrades because of this silly little connection! :(
