  • 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!

      2017 iMac + Thunderbolt Display

      There are WAY too many negative reviews on this adapter --- and most are likely nonsense. Just connected my 2017 iMac (27" Retina) with this adapter directly There are WAY too many negative reviews on this adapter --- and most are likely nonsense. Just connected my 2017 iMac (27" Retina) with this adapter directly to my Thunderbolt Display (purchased in 2015). Works FLAWLESSLY! It recognized it, fired right up and there are no issues. Stop reading all the negative reviews -- if your set-up is like mine ... This cable will work. Buy it and move on!

      Worked great: Apple Firewire Thunderbolt 2 -> 2017 MBP Thunderbolt 3

      I have a couple of old Sony camcorders that only have Firewire interface for pulling video off of them, and historically I have used an Apple Firewire Thunderbo I have a couple of old Sony camcorders that only have Firewire interface for pulling video off of them, and historically I have used an Apple Firewire Thunderbolt 2 "dongle" to accomplish the task. Now that I have a shiny new 2017 MacBook Pro with Thunderbolt 3, aka USB-C, I needed a way to bridge the gap between the old and the new. After reading the various reviews, it became apparent that this particular use case should work fine since my need is to go from legacy Thunderbolt 2 to Thunderbolt 3. So I purchased the adapter from the Apple store, plugged everything together, and like magic, Final Cut Pro recognized my old camcorder and pulled video from it just like the old days. This is literally the only reason I would use this adapter, but for my purposes it works perfectly. I docked a star from my rating purely because of the crazy cost -- $50 seems like a whole lot of money for a simple dongle. But it is Apple after all.... :-)

      Outrageous UK price

      Have just spent £29 in Apple Store purchasing Thunderbolt to FireWire cable from “expert” who obviously was unaware that latest spec iMac now has only USB-C. Ap Have just spent £29 in Apple Store purchasing Thunderbolt to FireWire cable from “expert” who obviously was unaware that latest spec iMac now has only USB-C. Apple even confuse their own people by referring to this as Thunderbolt 3! Now need to spend around £50 for extra USB-C to thunderbolt adapter. Two years ago Apple reduced the price of these from $49 to $29 as part of a reduction of most USB-C cables, but have sneaked them back up to $49! I regret spending almost £3000 last year on top of the range iMac and will stick to PCs in future which are not a customer rip off!
