    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 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.

    Connect USB-C 3.1 drive to Macs with Thunderbolt 2

    I bought this adapter to connect an external SSD USB-C (3.1) drive to my MacBook Pro and iMac with Thunderbolt 2 ports. The spec indicated that the device was bi-directional and with macOS Sierra (which I have) this would work. It didn't! I connected up to each computer and tried two different Thunderbolt cables, but the drive wasn't recognised and there was no indication that it was getting power from the port. It seems I have to revert to using a USB C to USB A cable with the drive. Very disappointed.

    It works also with other PC

    Wonderful.
    I own a QNAP Thunderbolt 2 NAS, and a Windows PC equipped by a GA-X99P-SLI motherboard, with Thunderbolt 3 port.
    This adapter allowed me to connect the NAS with this motherboard and works flawless!
    It's very cheap compared to other found on Amzn (twice the price)

    Great!

    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!
