“If you previously used iTunes to sync apps or ringtones on your iOS device, use the new App Store or Sounds Settings on iOS to redownload them without your Mac,” Apple tells users in the update prompt. Today, Apple quietly released iTunes version 12.7 for both Windows and macOS, and the most immediate change is that it no longer contains any options for syncing apps or ringtones to your iPhone, iPad, or iPod touch.
It’s no longer a place for you to get iOS apps, but it’s still got movies, TV shows, audiobooks, and podcasts. ITunes for PC and Mac is putting the emphasis back on being an app for music.
