    I have an iMac that I bought about 6 years ago in the time of Mac OS X 10.6.

    Does it have USB 3 or USB 2 ports? Is there a way to see?

    If I buy an external hard drive for backup (Time Machine) intended for USB 3, will it work on my machine if it is USB 2?

    Thanks for your help.

    USB 2 ports have black plastic inserts. USB 3 ports have blue plastic inserts on PCs. I'm not sure about Apple products.

    Devices are backward compatible so a USB 3 external will work in USB 2 ports. I have 6 external hard drives. Some 2 and some 3. My computers have USB 2 and USB 3 ports. I can use any of the externals in any of the USB ports on the computers.
