Update contact information in Contacts on Mac
You can change or add more information to your contacts at any time. For example, you can add a nickname for a friend.
In the Contacts app on your Mac, select a contact, click Edit at the bottom of the window (or use the Touch Bar), then click Info.
Make changes to the contact information.
You don’t need to fill in every field — empty fields don’t appear in the contact card.
Change the picture: Click Picture, then change the picture.
Add a company: Click the Company tickbox. You can enter a company contact person in the First and Last name fields below the Company name field.
Add a phone number extension: Enter the phone number, a semicolon (;), then the extension number.
Change the ringtone or text tone: Click the tone pop-up menu, then choose the sound you want to hear when the contact calls you on your Mac or sends you a message.
Add a field: Click the Add button , then choose a field. For example, add Profile to include a contact’s Twitter, Yelp or other social media username.
Change a field’s label: Click the label, then choose a different one. For example, to enter a work email instead of home email, click the label Home, then choose Work.
Remove a field: Delete the information in the field, or click the Remove button .
Note: If you use an Exchange account, those contact cards can include only three email addresses, and there are limits on the number of phone numbers, names, messaging addresses and street addresses.
If you edit a contact in a read-only account such as Exchange or Google, the changes you make appear only in Contacts.
