Cisdem has given us ContactsMate 3 for Mac (http://tinyurl.com/hfay7j8). It’s an update of the contact management software that will analyze, report, and fix issues with OS X Contacts.
It will also and export the Mac Address Book to different formats for contacts back-up or syncing. With version 3, you can make groups respectively for your family, friends, colleagues, clients or work contacts, etc. Also, when problematic contacts are found out and sorted, you can perform bulk modifications on the similar questionable Contacts or neglect these problems as you will.
A demo of ContactsMate 3 is available for download. Registration is $15.99. The app requires Mac OS X 10.7 or higher.
