Step 1: Choose and scan your iTunes backup
After installing and launching the software, you'll get a list of all the devices that are synced with your Mac’s current copy of iTunes. Highlight a device by clicking it and then click Start Scan.
Step 2: Preview and Select
After you click "Start Scan", you’ll immediately be able to view thumbnails of all media files previously synced to iTunes from that device. Browse these files in categories (Camera Roll, Photo Stream, Contacts, Messages, Messages Attachments, Call History, Calendar, Notes, Reminders, Voice Memos and Safari Bookmark) by clicking one of these options on the top left of the window.
