  • 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 with Drobo 5D, but watch out for shutdown error (iMac Pro)

      Important to note that when shutting down the iMac Pro with Drobo plugged in and turned on, the Drobo causes an error in the computer and the computer will actu Important to note that when shutting down the iMac Pro with Drobo plugged in and turned on, the Drobo causes an error in the computer and the computer will actually restart itself rather than shut down and an error message is displayed upon logging in. This happened through repeated tests consistently. I assume this is because the Drobo doesn't unmount itself correctly when the computer attempts to shut down, which causes the error. It took me a long time and series of trial and error (removing apps, deleting various folders, etc) to figure out what exactly was causing this shutdown issue. And it turns that while the Drobo device was connected and turned on, and accessible on the computer, the problem persisted. When the Drobo was shutdown or the cord physically unplugged from computer (note: right click>eject will not help, you need to physically unplug it), the iMac Pro shutdown normally. Using this same Drobo and thunderbolt 2 cord causes no shutdown issues when plugged directly into my Macbook Pro without the USB-C adapter. Therefore I can only surmise it is the adapter causing the communication/transmission error at shutdown. Hope this helps. Would be 5 stars without this problem. 3 stars because of it.

      Doesn't work for Video, dont waste your money.

      Originally bought it for a Thunderbold 2 Black Magic Video converter, doesn't work at all. Just now I tried it with my display on my new 2017 MBP, doesn't work Originally bought it for a Thunderbold 2 Black Magic Video converter, doesn't work at all. Just now I tried it with my display on my new 2017 MBP, doesn't work either. Apple, you make nice things, but this product is the one that gives you a bad rep... its utter garbage. Fifty bucks wasted and you cant even sell it because nobody buys them.

      Allows Dell laptop to drive thunderbolt display

      I have a dell laptop with thunderbolt 3 (USB-C) and a thunderbolt display. While this may not be officially supported, this adapter allows the dell laptop t I have a dell laptop with thunderbolt 3 (USB-C) and a thunderbolt display. While this may not be officially supported, this adapter allows the dell laptop to drive the display and sound. The FacetimeHD and ethernet do not work as windows complain not having the supported drivers. I am happy as I have been using my thunderbolt display with my mac. Now I can use the same display for the dell laptop as well.
