The iTunes program, included as part of the Mac OS X operating system, has a sync feature that shuttles information between your Mac and iPhone using a USB cable or a Wi-Fi connection. Syncing ensures that content on your iPhone, including music, movies and app data, is up-to-date with corresponding files on your Mac.
Sync Using USB Cable
