  • 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!

      Only works one way :(

      Older devices -> 2018 Macbook Pro = ok Newer (usb-c) devices -> 2013 Mac Pro = nope! Maybe this works fine connecting thunderbolt 2 devices to a new macbook Older devices -> 2018 Macbook Pro = ok Newer (usb-c) devices -> 2013 Mac Pro = nope! Maybe this works fine connecting thunderbolt 2 devices to a new macbook pro. But if you were wanting to use it to connect new devices to a computer with legacy ports (re: any computer other than the newest macbook pros) than you're SOL. $50 spent, and I still can't connect a usb-c hard drive to my Mac Pro tower.

      Works perfectly for me for an Apogee Duet 1 (with Firewire 400 port)

      I read most of all the negative reviews and hesitated to buy... But I took my chance because I still have seen a couple of good reviews related to audio equip I read most of all the negative reviews and hesitated to buy... But I took my chance because I still have seen a couple of good reviews related to audio equipment. I have a first generation Apogee Duet audio interface that has a Firewire 400 connector. That Apogee Duet 1 audio interface is perfect for my needs and I really didn't want to buy a 800$ Duet 2 (now USB) just because of a connector type... I was already using a Thunderbolt 1 to Firewire adapter to the Duet from my old Macbook Air 2011. I just got a new Macbook Pro w/touch bar and the 4 Thunderbolt 3 ports. I couldn't find a single Thunderbolt 3 to Firewire adapter, so I decided to try to daisy chain the 2 adapters, and it worked flawless, hot plugged, no reboot, on first try, nothing further to do. Perfectly satisfied. Yes... 59$ is very expensive for an adapter, but with that kind of result, I give it 5 stars.
