  • 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!

      Misleading Information - Thunderbolt 3 to Thunderbolt 2 Adapter description

      Beware! The description on the website is misleading and inaccurate. On the website it says 'As a bidirectional adapter, it can also connect new Thunderbolt Beware! The description on the website is misleading and inaccurate. On the website it says '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.' This statement can be UNTRUE depending on the model of your Mac. I have a 2013 Macbook pro with a Thunderbolt 2 female port. I use all my USB ports on the laptop for other devices and need to utilize the Thunderbolt 2 port for my iPhone. After reading the description on Apple's website, I purchased this adaptor from a 3rd party, only to find that it will need another cable for it to work. And of course, no one is selling that thunderbolt 2 to thunderbolt 2 cable anywhere. If you are in a similar situation as I, you are better off buying a USB hub and forgetting about this adaptor.

      Didn't Work with G-Drive Thunderbolt3 (USB-C)

      Purchased a G-Drive 4TB that only had a Thunderbolt 3 (USB-C) connection. Using the provided USB-to-USB-C cable wasn't providing fast enough speed to transfer Purchased a G-Drive 4TB that only had a Thunderbolt 3 (USB-C) connection. Using the provided USB-to-USB-C cable wasn't providing fast enough speed to transfer 4K 30P ProRes files in real time for editing, compared to the other identical,Thunderbolt2 drive we'd been using. Got this adapter, it didn't even seem to connect. Drive wouldn't even spin up despite repeatedly attempts. Drive always worked fine (just not fast enough) when connected via USB, but never when connected using this adapter to the Thunderbolt2 port on my iMac. I think it may not be suitable for this purpose.

      Keyboard stops working

      I've been using this for a week now to connect to my Thunderbolt Display with a wired keyboard. The keyboard works maybe 50% of the time when I plug in. Very fr I've been using this for a week now to connect to my Thunderbolt Display with a wired keyboard. The keyboard works maybe 50% of the time when I plug in. Very frustrating and don't know how to get it to connect regularly.
