IMac won’t recognize My Passport

My new iMac will not recognize my WD My Passport. Website says it’s a legacy hard drive and they won’t advise me how to utilize the product they sold me. I’m desperate to retain the contents on the external hard drive. How do I get my computer to recognize this legacy device?
