My address book and Mac mail are not working nicely together. I have a contact in my address book, and for this example we will call him John Doe. Here is John Does info. First Name: John Last Name: Doe E-mail address: email@example.com When I receive e-mails from 'firstname.lastname@example.org' in my Mac Mail application the 'From' field displays some random nickname for 'John Doe' even though his e-mail address matches the one in the address book. How do I get 'John Does' name to appear in my Mac Mail instead of some random nickname. In my understanding, I thought Mac Mail synced up e-mail addresses with the contact book and displayed the appropriate corresponding name. Does that make sense?
