    Hi all,

    I purchased the Apple USB-C Thunderbolt 3 to Thunderbolt 2 adaptor which turns out isn't working on my 2016 MacBook (although I'm pretty sure I have used it before on the laptop). I've got a Lacie thunderbolt drive that I'd like to use on the MB, however I can't find out whether this is possible based on what dongles/cables are available.

    Had anyone got any thoughts on this?

    Thanks!

    The 12" MacBook doesn't support Thunderbolt devices, only the MacBook Pros have Thunderbolt USB-C ports.

    USB-C != Thunderbolt 3
    Thunderbolt 3 = USB-C

    If the computer supports Thunderbolt 3, that port will have the USB-C shape (USB-C is only the design of the port).
    However, if the computer has USB-C it doesn't automatically mean the computer supports Thunderbolt 3 over that port.

    Macbook happens to be one of those cases where the USB-C only supports USB 3.1 (5Gb/s) and not Thunderbolt 3 (40Gb/s).

    MacBook also doesn't support the newest USB 3.1 Gen 2, only the old (renamed) Gen 1. The MacBook Pros support the latest USB.
