I bought this refurbished 2015 MacBook Air from one of the highly-rated suppliers online. It has worked perfectly for years. I recently decided to give it to my wife. It seems that, in preparing the MBA for the transfer, entered my Apple ID or PW incorrectly. Apple reported that my computer is now locked, and told me that instructions to unlock it were being sent to my email-address, giving an outline of the address "belonging to me" that Apple would be using. . It resembled no eail-address that I. have ever used. As an. alternative, it asked me as a security-question for my date of birth. It rejected my answer. Where do I go from here ?
