Address Book Clearout will remove duplicates in your Contacts database  as well as fixing other problems, such as repeating fields.

A single click will remove all the duplicates, another click will remove the partial duplicates. But Clearout goes further and will search out possible matches. You can combine or update these matches and then delete the duplicate in a complete and seamless workflow.

Any field or group of fields – phone numbers, addresses, social profiles – can be moved between cards. Spot a mistake? – fields can be edited with a double click.

Graphical display of group membership makes it easy to organize groups and allows you to visually analyse how you are using groups.

Address Book Clearout has been designed so you have the option to examine the duplicates before you remove them.  This allows you to be sure of which contacts are being deleted but more importantly helps in tracking down the source of recurring problems.

Your contact information is important to you. Clearout lets you keep complete control over which data is discarded.

Legacy operating systems. This version of Clearout is designed for Yosemite and works best on Yosemite. To support users of the previous version who are on legacy systems, this release of Clearout will work with all systems from Snow Leopard up, but appearance and stability may not be optimal.
