SyncMate will sync contacts and calendars between Mac and Android Samsung devices for absolutely free - data will be synced between calendar and address book apps on devices, not just transferred as a backup file.
With Expert Edition of SyncMate you can sync Android Samsung images, videos, music, playlists, folders with files, bookmarks, etc. Data can be synced automatically - all you need is to set parameters of sync once and they will be implemented during further sync sessions.
SyncMate Expert allows mounting your Android Samsung as Mac disk and not only browsing its content in Finder, but also transferring any files between Mac and Samsung. You can manage SMS on Mac, view call history, or even back up Android Samsung data on Mac.
