Apple Mail Sender Confusion
My wife and I have separate Macs on our home network, and we share the same primary gmail email address in an account under my name. We use Apple Mail as our mail client. However, when I send email from my Mac, it shows my wife as the sender, and when she sends one from her computer, it shows me as the sender. Where does the sender name reside on each computer? I've checked through Settings on my computer and only see my name. I've seen some other postings on the community discussion about this, but haven't found anything useful. For what it's worth, I looked up both our names up in Contacts on my Mac; she appears twice, and on one record, three cards are listed, one labeled Contacts and the other two labeled for my two iCloud accounts. Under my name, there are seven listings, none of which show any cards.
I should also add that emails sent from my iPhone using Mail also show her as the sender.
Any idea how I can get the right sender name on the correct computer?
