The new version of macOS, 10.15 Catalina, is getting rid of iTunes in lieu of three dedicated media management apps. Replacing the storied software is Apple Music, Apple TV, and Apple Podcasts. MacOS 10.15 will also use Finder to back up, restore, and update a connected iOS device, but users still won't have unfettered access to their iPhone's or iPad's file system.
