  • 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!

      Please, do not buy it!!!

      The main (if not only) reason why anyone needs this overpriced accessory is to reconnect your old thunderbolt-2 display (such as a $1000 Apple Thunderbolt, for The main (if not only) reason why anyone needs this overpriced accessory is to reconnect your old thunderbolt-2 display (such as a $1000 Apple Thunderbolt, for example) to your brand-new Mac Laptop. To put it simple: IT DOES NOT WORK. The new Mac is not fully compatible with thunderbolt-2 displays period. Technically, if you find the way to establish the connection, the display will work (happened to me on some lucky days), but on 50% of the times it will simply not turn on and nothing what you do will change this outcome. Dear Apple, I have no words to express my frustration with your awesome idea of releasing all-the-same port Macbook Pro Laptop, by default dependable on your price-charged adapters, and not even developing the adapters that actually work with other Apple products. Not even mentioning moving a sound port to the right, making the headphone cable to go under my right hand... Shame on you! It is my second big frustration with Apple products after my iPhone 6s bended by itself in my jeans pocket and Apple representatives had not accepted it as a bug.

      Overpriced but now have two additional monitors for my 2017 MBP

      My work computer is a 15" MBP with only USB C ports. I was using the Duet Display app to connect the MBP to my 12.9" iPad for more screen real estate via USB C My work computer is a 15" MBP with only USB C ports. I was using the Duet Display app to connect the MBP to my 12.9" iPad for more screen real estate via USB C to Lightning cable but needed more monitors for the type of work I was doing. I already had a 2013 iMac as my main computer. This enabled me (with a thunderbolt 2 cable) to use my iMac as a third monitor with my 15" MacBook pro and 12.9" iPad. It's made me a lot more productive. Rant: For the amount of money Apple makes us shell out for the MBP with only USB C ports they should include this and all the other adapters with the laptop. But happy it's working :)

      Works Just Fine.

I almost didn't get it because of that but since there aren't many options for this adapter I figured I would try it. It is connected to about a dozen device which all function normally. Despite the fact that is says it won't work with DisplayPort, it will, the display port just has to be daisy chained behind a thunderbolt device. I have it connected to a CalDigit TB2 station - Drobo - Mini Display port to HDMI. In total it drives two 1080p displays, the drobo, gigabit lan, esata and a bunch of usb devices flawlessly.
