  • 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!

      Works as described

      use case: connecting to displays This adapter works when connecting my 2017 usb c/thunderbolt 3 macbook pro to an old thunderbolt display at work. This ad use case: connecting to displays This adapter works when connecting my 2017 usb c/thunderbolt 3 macbook pro to an old thunderbolt display at work. This adapter does not work when connecting the same laptop to a dell u2515H via the mini display port cord at home. i had to buy a display port -> usb c cord for this. My 2012 macbook air would work with both displays. Slightly confusing because thunderbolt and mini display port are the same shape plug. But this adapter won't take a display port signal - as outlined in the description.

      wow

      This absurdly expensive port simply does not work. Plain and simple. Plug it into my iMac with Thunderbolt 2 ports - no devices registered. I might as well This absurdly expensive port simply does not work. Plain and simple. Plug it into my iMac with Thunderbolt 2 ports - no devices registered. I might as well have just shoved $65 into the port - would have achieved the same result - nothing.
