  • 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.

      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.

      It works if you know what you're buying

      All the bad reviews of this product are people who don't know what monitor they own and/or don't understand what this adapter does. Thunderbolt 1 and 2 reuse All the bad reviews of this product are people who don't know what monitor they own and/or don't understand what this adapter does. Thunderbolt 1 and 2 reuses the Mini Display Port. Thunderbolt 3 uses USB-C. This adapter changes the USB-C Thunderbolt connection to a Mini Display Port Thunderbolt connector. It is NOT a USB-C Thunderbolt 3 to Mini Display Port connector. So, if your monitor uses a Mini Display Port input like the Apple Cinema Display, this will not work. Your monitor MUST use Thunderbolt as its input. I'm using it on dual 34" ultrawide LG monitors and these adapters work perfectly.

      Does what it says on the tin

      This is a review of the actual product, not the price!! If you actually take the time to read the product specs, this adapter converts Thunderbolt 3 to Thund This is a review of the actual product, not the price!! If you actually take the time to read the product specs, this adapter converts Thunderbolt 3 to Thunderbolt 2/1. It is NOT a DisplayPort adapter. I bought this so I could use my old Elgato Thunderbolt 1 Dock with my new MacBook Pro 2017, and it works perfectly! I can access the Gigabit Ethernet, HDMI, audio and USB3 ports on the dock. I can also use it with my Apple Thunderbolt 1 to Gigabit Ethernet Adapter. I am very pleased with this and it was well worth the £50 to keep using the old dock/adapters working. A lot of the negative reviews of this product are to do with the price. Only you can decide if it is worth the price. For me it was, because I can keep using my existing dock/adapters going, saving me £270. Result! :-D

      Excellent adapter to link new 2017 iMac to my Thunderbolt 2 CalDigit Dock

      Just upgraded from my trusty Late 2012 13" Retina MacBook Pro to a new 27" iMac 2017. As I had previously invested in a CalDigit Thunderbolt 2 dock to use with Just upgraded from my trusty Late 2012 13" Retina MacBook Pro to a new 27" iMac 2017. As I had previously invested in a CalDigit Thunderbolt 2 dock to use with my MacBook, I needed a Thunderbolt 3 to Thunderbolt 2 adapter to link my Thunderbolt 3 iMac to the CalDigit dock, and so I bought this Apple adapter. So easy to use and it works perfectly. The BenQ 27" monitor is driven via the HDMI output on the CalDigit Thunder2 Dock. Recommended adapter!
