In this lesson for Messages on the Mac, I look at how you can create a contact card from the messages app. You wold use this when you receive a message from someone who is not in your contacts, but you would like them to be. If they are not, you can easily create a contact card for them in the Contacts app directly from Messages. If the contact who sent to a message is in your Contacts, you can then easily open that contact in the Contacts app directly from Messages. See how this all works in the video above.
