Today Research In Motion announced that it will begin offering a Mac OS X version of its BlackBerry Desktop software starting in September of this year.

The new application will allow Mac owners to sync iTunes playlists, calendars, contacts, notes, and tasks between their Mac computers and their BlackBerry smartphones. The new application will also allow users to add or remove applications from a BlackBerry, update device firmware, backup and restore, and even manage multiple BlackBerry smartphones. It will run on Mac OS X 10.5.5 and above.
