One Must-do Thing Most User Do not Know After iTunes Failed to Sync
Typically iTunes will sync with an iOS device without incident, but sometimes iTunes just won’t sync at all. If you find yourself in that frustrating situation, firstly, you may do following steps to try to fix it and get the iPhone, iPod, or iPad syncing with iTunes on a Mac or PC again. And this guide will show you one must-do thing most users do not know after iTunes failed to sync.
Try again after each step to let iTunes sync with device:
- Make sure that you have the latest version of iTunes.
- Connect your device to your computer with a USB cable, then select your device in iTunes. If your device doesn't appear in iTunes, you need to fix that issue before you can continue.
- Turn off both your computer and your iPhone, iPad, or iPod touch. Then turn them on again.
- If you use a Mac, skip this step. If you use a Windows PC and iTunes won't respond or your backup never finishes, you might need to update, change, disable, or uninstall your security software.
- If you own more than one computer, try to make a backup on your other Mac or PC. Or, use iCloud to back up your device and restore from your iCloud backup.
