Before Beginning, Make Sure You Download Latest Versions of iTunes:
People keep facing a lot of problems in iTunes while they notice they didn’t upgrade iTunes to the latest versions. So before we start make sure you download the latest versions of iTunes either on Mac OS X or Windows..
Download iTunes 11.0.4 (Apple’s official Website).
So shall we start… Just give it a try..
1: Quick & relaunch iTunes, then perform a manual sync.
Simply quit out of iTunes, then relaunch the app, and try syncing again. Sometimes this is enough to get things working again.
Maybe you will notice that sync works on your, but you will see there is no content, music, apps, or movies is moving over to the iPhone, iPad, or iPod, check the following:
- Under the “Summary†tab, check if “Manually manage music and videos†is enabled or not, if it is then try toggling it off and on again then manually drag a song or movie over to the iOS device to force manual syncing
- Look under the “Musicâ€, “Moviesâ€, “Appsâ€, “TV Shows†or respective tabs and be sure that “Sync Musicâ€, “Sync Movies†etc is checked and enabled
- Try checking and unchecking those boxes, then hit the “Sync†button again.
These content and media transfer issues are often just a misunderstanding of how those preferences work. Personally, I prefer to manually sync my music and media, so I have all of the individual content sync features disabled and sync everything myself through drag & drop.
- Open iTunes with the iOS device attached to the computer through USB
- Pull down the “Store†menu and choose “Deauthorize This Computerâ€
- Now go back to the Store menu and choose “Authorize This Computerâ€
- Fill in the Apple ID and password information, then choose “Authorizeâ€
iTunes Authorization basically tells Apple that the apps, music, and media you have purchased belong to you, and that you have the rights to them and thus that media can be copied and synced to your iOS devices.
Still facing problem ? Maybe you want to give your iPhone a quick reboot, all what you have to do is Holding down the Power button and Home button simultaneously until the device restarts. Technically, that approach is called a Hard Reboot because it forcibly restarts the iOS device, but in situations where things are acting up, crashing, or just not behaving properly, it’s usually more effective to force reboot than to use the standard power-off approach.
Restarting your computer may fix such problem as sometimes computer doesn’t read iTunes files and mess, so with restarting your computer or Mac can put everything at the right place. This is particularly true if the issue has to do with a malfunctioning daemon like the iTunesHelper Service or the AppleMobileDevice Helper process.
So if everything above I’ve written didn’t work with you, you will have to play with the last card you have which is Wi-Fi sync. Try using Wi-Fi syncing instead to see if that works. USB syncing is usually the most reliable method, and it’s not terribly uncommon for wi-fi sync to be a bit more picky.
5b: Wireless Syncing Randomly Stopped Working
If you find wireless sync to suddenly stop working, you typically just have to toggle the feature on and off again to get it functioning again, which must be done by connecting the iPhone, iPad, or iPod to the computer by USB and rechecking the “Sync over Wi-Fi†option again under the Summary tab. This is basically like enabling it again for the first time, and only takes a moment:
