How do I connect a USB drive to my iMac?

Hi there,

Ignoring the 'plug it into your USB socket' previous comments(!) I assume you're on a newer (M1) iMac? If so, as the new machines don't have USB ports any more, you need to get an 'Apple USB-C Digital AV Multi-port adaptor' - you can then attach any USB cable device (and also an HDMI cable if necessary). Unfortunately they're not cheap!

Hope that helps

Plug it in to the USB socket on your mac.

Plugging it into a USB port is a great start.

You will need a USB-A to USB-C adapter. Check Amazon
