  • 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!

      Failed to connect Mac Mini Thunderbolt 1 to external USB C hard drive

      I was really excited to find this adapter and after spending $50 on the adapter and another $20 on a Thunderbolt cable, I now have $70 of useless connectors sit I was really excited to find this adapter and after spending $50 on the adapter and another $20 on a Thunderbolt cable, I now have $70 of useless connectors sitting on my desk. My external drive is powered and I have OS X Sierra as required but the drive does not appear in disk manager nor on the thunderbolt bus in system report. This thing is going back.

      Expensive, but works for what it was meant for.

      I read all the negative reviews of this product and almost did not by my new MacBook pro 2019. But I think people are expecting more than it was designed for. T I read all the negative reviews of this product and almost did not by my new MacBook pro 2019. But I think people are expecting more than it was designed for. This adapter works beautifully for connecting MacBook pro to legacy Apple Thunderbolt Display. I was working with a 2011 legacy MacBook and and Apple Thunderbolt displays, both of which I was very dependent on. I have a legacy Apple ThunderBolt display both at home and at work. I needed these displays to work with a new MacBook Pro as any new machine would be so expensive that needing to also replace displays would be a no go. So I had been holding off on the MacBook pro purchase, nursing my legacy machine along. Finally the logic board failed in the legacy 2011 machine and I had no choice. The people in the Apple store were young enough they did not even know what I was talking about when I said I wanted to connect the new macBook pro to the thunderbold display. So I had to rely on the description on the adapter package. It clearly stated it would work with Apple ThunderBolt display, and since 1984, for the most part, what Apple says on their packaging for the most part is accurate. So I bought the new machine and the adapter. Plugged in the adapter to the connector on the Thunderbolt display and plugged in to the Thunderbolt 3 port on the macbook pro. Turned computer on. Image showed on the TB display instantly. Now for clamshell mode. Plugged the power supply in to a second thunderbold 3 port on the computer, closed the cover, and the main display instantly transitioned to the TB display. So I have two connections to make to go into desktop mode. Connect power and connect the display. Same 2 connections as before. Works great with the Apple Thunderbolt display. All ports on the thunderbolt display continue to work. My only complaint is on the price. $49 for an adapter? That cost this review one star. Come on Apple!!! You made the TB display and sold it to me for $1000, then eliminated the TB2 ports on the new machines. I spent $4000 on the new MacBook Pro. There should be some sort of program where owners of original TB displays could get this adapter for free. But thanks at least for making it so i did not have to repurchase displays.
