WD Mybook thunderbolt duo for new imac

I just purchased the new imac. As I have a WD Mybook thunderbolt duo which only has thunderbolt ports, I bought a thunderbolt to usb-c cable (the new imac just got usb-c and usb ports) to connect between the imac and the wd. However, the new imac failed to recognize the wd and the wd became very hot after running for a while. Is there any way to solve? Thanks!

Hello giianluigi,

I would suggest you to use thunderbolt cable to connect your new iMac with My Book Thunderbolt Duo. If issue still persists, you should follow below article in this concern:
