The latest version of iTunes compatible with iOS 14 is iTunes 12.11. It is important to have the latest version of iTunes installed on your computer to ensure smooth synchronization and backup of your iPhone running iOS 14.
To update iTunes to version 12.11, you can follow these steps:
1. Open the iTunes application on your computer.
2. If you're on a Mac, click on "iTunes" in the menu bar, and then select "Check for Updates." If you're on a Windows PC, click on "Help" in the menu bar, and then select "Check for Updates."
3. iTunes will check for any available updates and prompt you to download and install the latest version if one is available.
4. Follow the on-screen instructions to complete the update process.
Alternatively, you can visit the official Apple website (apple.com/itunes) and download the latest version of iTunes from there. Make sure to select the appropriate operating system for your computer (macOS or Windows).
It's worth noting that with the introduction of iOS 15, Apple has transitioned away from iTunes and replaced it with the Finder app on Mac and the Music app on Windows for managing device synchronization and backup. Therefore, if you plan to upgrade your iPhone to iOS 15 or later, you won't need to worry about iTunes compatibility as it is no longer required.
