Export and archive contacts in Contacts on Mac
You can export selected contacts to send to others or to import on another computer. Or archive all your contacts so you have a backup copy of them.
Note: To exclude notes and photos when you export contacts, choose Contacts > Preferences, click vCard, then deselect “Export notes in vCards” and “Export photos in vCards”.
In the Contacts app on your Mac, do any of the following:
Export some contacts: Select contacts or a group, then drag them to the desktop. Or select them, then choose File > Export > Export vCard.
The contacts are exported as a vCard file (.vcf).
Export all contacts: Choose File > Export > Contacts Archive, choose a location, then click Save.
The contacts are exported as an archive file (.abbu).
If you made your card private, fields you opted not to share are not included when you export your card.
