  • 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!

      Ovberpriced, useless, working one should have been included with Mac Pro

      Does not work. Too expensive. And why did I need to buy one in the first place? Apple should have included this in the box. The Mac Pro is not "pro" in that Does not work. Too expensive. And why did I need to buy one in the first place? Apple should have included this in the box. The Mac Pro is not "pro" in that you cannot use it for real work without buying a bunch of extra stuff -- and then even those don't work. The experience needs to be: walk into a customer site, plug into their A/V setup, present. That's what a "pro" model should do. These adapters don't even bridge that gap.

      Worked perfectly out-of-the-box

      I appreciate that many are having killer issues. I tried a cheaper, generic-brand USB-C-to-Thunderbolt2 converter and it didn't work. With pretty strong doub I appreciate that many are having killer issues. I tried a cheaper, generic-brand USB-C-to-Thunderbolt2 converter and it didn't work. With pretty strong doubts I grabbed this dongle at the local Apple Store, hooked it up, and hey presto mundo! I'm driving my 27-inch Mac Thunderbolt display (purchased mid-2014) with a 2016 13-inch MacBook Pro (4xT3=USB-C ports) that's running Sierra 10.12.6, using Intel Iris Graphics 550 with 1536 MB. Audio feeds through fine (in and out); USB-B ports on the display are recognized and work fine; I don't chain T2 nor used wired Ethernet off the display so can't confirm, but suspect they work, too. Thunderbolt firmware versions: v22.1on the MacBook Pro busses, v26.2on the display (different numbering for different products). I hope this info helps, good luck!

      waste of money for audio interface

      won't support audio interfaces. apple has put me in dongle trouble with the macbook 2016. and none of them work. such bad buyer's remorse.
