  • 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!

      Unreliable and extortionately overpriced

      I bought this dongle along with a Thunderbolt 2 cable to connect my 2018 MacBook Pro to my 2013 iMac in Target Display Mode. That's 80 quid's worth of dongle/ca I bought this dongle along with a Thunderbolt 2 cable to connect my 2018 MacBook Pro to my 2013 iMac in Target Display Mode. That's 80 quid's worth of dongle/cable to solve this problem, so you'd expect it to be pretty decent wouldn't you? Unfortunately It is very unreliable to get it to work. It'll usually takes unplugging the cable and replugging it several times and spamming command F2 on the iMac keyboard, but eventually it'll connect. For best results log out of the user account on the iMac first. Sound will not work at all. My iMac shows up as a device in the volume settings but when I select it there is no sound. A quick Google shows this was a bug introduced in Mojave a year ago and is yet to be fixed. In summary, this is a ridiculously overpriced dongle, it's a hassle to make it work, and one of the features is broken and doesn't look likely to be fixed. Thunderbolt Display users: I tried this on an old Thunderbolt Display at work, one of those with the Magsafe 1 adapters on it, and it worked with no issue (although I didn't try sound).

      Connects a new MacBook Pro to an old Thunderbolt display

      This cable may not work for all use cases, but if you have a new MacBook Pro (mine is a 2018) and an old Thunderbolt Cinema Display, this will work perfectly wi This cable may not work for all use cases, but if you have a new MacBook Pro (mine is a 2018) and an old Thunderbolt Cinema Display, this will work perfectly without issue - and retain all the functionality of the display's hub. The price tag is a bit excessive, $29 would have been easier to swallow.
