Important: For those who use contact groups, please be aware that the individual contacts of your address book will be included in the export but your contact groups will not. The reason for this is Apple Mail cannot export auto-fill/auto-complete information, the export is completed by creating a new contact entry for previously email recipients/senders. Important: If you are interested in exporting the auto-fill/auto-complete history from your Apple Mail program, please make sure to complete that step prior to exporting your contacts.

Note: versions prior to 10.8 used address books instead of contacts.

This document will provide step-by-step guidance on how to export contact lists from Apple Contacts.
