Sync your iPhone to iTunes on our computer
To get iTunes content on your iPhone, you don’t actually install iTunes on the device itself, since iTunes is a desktop app for Windows or Mac. Instead, you use iTunes on your computer to sync or transfer music, videos, apps, and other media to your iPhone. Here’s how: Install iTunes on your computer: Download the latest version from Apple’s website and install it. Connect your iPhone: Use a USB cable to connect your iPhone to the computer. Open iTunes and ensure your device is recognized. Sync content: In iTunes, select your iPhone icon. Navigate through the tabs like Music, Movies, TV Shows, or Books. Check the content you want to sync, then click Apply or Sync. Transfer purchases: To add items already purchased on the iPhone, go to File > Devices > Transfer Purchases from [your iPhone] in iTunes. Use iCloud alternatives: For wireless syncing, you can enable iCloud Music Library, iCloud Photos, or use Finder on Mac (macOS Catalina and later) to sync content without iTunes. Following these steps will get your iTunes media onto your iPhone efficiently, keeping your music, videos, and other purchases up to date.
