Prevent iTunes or Finder from automatically syncing with your device

When you connect an iPhone, iPad, or iPod to your computer, iTunes on Windows or Finder on macOS may automatically sync your device. This can overwrite changes you made in iMazing, particularly for music and media management.

On Windows, you can disable automatic syncing globally for all devices. On macOS, since Catalina, you can only disable it on a per-device basis.

1. Open iTunes.
2. In the menu bar, select Edit > Preferences.
3. Click the Devices tab.
4. Check Prevent iPods, iPhones, and iPads from syncing automatically.
5. Click OK.
