Basic Start Up Questions

I am unable to get Time Machine to recognize the  My Passport external drive. When I installed the My Passport and it asked if I wanted to back up with Time Machine, I checked “decide later”. Cannot figure out how to get back to a place at which I can now answer that question “yes.”  I’ll be grateful for any suggestions. Thank you.

Hello,

Through your applications, look for the time machine backup app and follow the steps to setup a new backup. It should allow you to select the location for the backup.
