What's the Device for Updating with: Mac or PC?

If you cannot update with iTunes, then do so using the TV app or the Music app.

Two Major Steps: - Backup then Update

1. Backup First: Make a backup of your device using iCloud or your computer

2. Then, Update Using these Links:

• On the iPhone itself: Update your iPhone, iPad, or iPod touch - Apple Support
• From a Mac: Update software on iOS devices in iTunes on Mac - Apple Support
• From a PC: Update software on iOS and iPadOS devices in iTunes on PC - Apple Support
