  • 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.

      Thunderbolt only, NOT DisplayPort

      I bought this to use my existing monitor cable (Mini-DisplayPort to DisplayPort) with my new MacBook Pro (Late 2016). It doesn't work. You can use this ad I bought this to use my existing monitor cable (Mini-DisplayPort to DisplayPort) with my new MacBook Pro (Late 2016). It doesn't work. You can use this adapter to connect THUNDERBOLT devices to your brand-new MacBook Pro . It appears that you CANNOT use this to connect Mini-DisplayPort devices. I hope that this helps others considering the same thing.

      Beware TB3 devices can need more power than TB2 supplies

      As per a previous reviewer who was hoping to take advantage of the bidirectional nature of this cable to connect new Thunderbolt 3 accessories to a current or o As per a previous reviewer who was hoping to take advantage of the bidirectional nature of this cable to connect new Thunderbolt 3 accessories to a current or older mac with Thunderbolt 2 ports, this may not work if your Thunderbolt 3 device gets it's power from the Thunderbolt 3 connection. Thunderbolt 3 is capable of delivering a lot more power than Thunderbolt 2 so may need more power than your Thunderbolt 2 port can supply. I know this to be the case with the Sonnet Fusion PCIe SSD Thunderbolt 3. If your Thunderbolt device has it's own separate power supply there is a chance it will work, but as per some recent articles in the mac press the new MacBook Pro will not support any currently on the market Thunderbolt 3 devices as they all use the Generation 1 Texas Instruments Thunderbolt controller. New products now reaching the market and due to appear from November 2016 onwards are more likely to include the Generation 2 Ti controller which is supported. I imagine this lack of compatibility might also reach backwards when trying to connect those TB3 devices to a TB2 equipped mac.

I can't as there is a software/compatibility issue, I have checked this on other Macbook's and Thunderbolt displays, this adaptor only works with Macbook Pros.

      Unreliable and extortionately overpriced

      I bought this dongle along with a Thunderbolt 2 cable to connect my 2018 MacBook Pro to my 2013 iMac in Target Display Mode. That's 80 quid's worth of dongle/ca I bought this dongle along with a Thunderbolt 2 cable to connect my 2018 MacBook Pro to my 2013 iMac in Target Display Mode. That's 80 quid's worth of dongle/cable to solve this problem, so you'd expect it to be pretty decent wouldn't you? Unfortunately It is very unreliable to get it to work. It'll usually takes unplugging the cable and replugging it several times and spamming command F2 on the iMac keyboard, but eventually it'll connect. For best results log out of the user account on the iMac first. Sound will not work at all. My iMac shows up as a device in the volume settings but when I select it there is no sound. A quick Google shows this was a bug introduced in Mojave a year ago and is yet to be fixed. In summary, this is a ridiculously overpriced dongle, it's a hassle to make it work, and one of the features is broken and doesn't look likely to be fixed. Thunderbolt Display users: I tried this on an old Thunderbolt Display at work, one of those with the Magsafe 1 adapters on it, and it worked with no issue (although I didn't try sound).

      Amazed - Firewire 400 still viable

      It works! [T3 > T2 adapter] + [T2 > Firewire 800 adapter] + [Firewire 800 > FireWire 400 adapter] and there is still enough juice to run a portable Firewire 400 It works! [T3 > T2 adapter] + [T2 > Firewire 800 adapter] + [Firewire 800 > FireWire 400 adapter] and there is still enough juice to run a portable Firewire 400 disk! Looking forward to Apple's next leap forward, when the number of adapters I'm carrying around to connect my investment in HDD technology that Apple pushed then abandoned may require a wheeled suitcase.
