AddressBook Cleaner for Mac is designed to eliminate duplicate entries from your address book with just a few clicks. With the trial version, you can scan for duplicates but won't be able to actually delete them, although you can still get an idea of how the app works.
AddressBook Cleaner for Mac needs direct access to your contacts in order to operate. Before the app starts to search your address book for duplicate entries, you can check which conditions will apply to the search. We checked a couple of fields and performed the search. Duplicate entries populated in the main application window within seconds and we were able to select which ones to keep and which ones to delete. All entries you wish to keep will be marked as "keep" in green, and the ones you wish to remove will be marked as "delete" in red. We marked a couple of entries as "delete" but were not able to actually remove these due to the limitations of the trial version. Up to this point, the app performed smoothly, though.
AddressBook Cleaner for Mac looks like a decent solution for eliminating duplicate entries in OS X address book. The application proved to be very good at finding duplicates, but the trial version won't let you see if it's just as good at getting rid of them.
Editors' note: This is a review of the trial version of AddressBook Cleaner for Mac 2.80.
