iTunes is going places.
Download macOS Catalina for an all‑new entertainment experience. Your music, TV shows, movies, podcasts and audiobooks will transfer automatically to the Apple Music, Apple TV, Apple Podcasts and Apple Books apps, where you’ll still have access to your favourite iTunes features, including purchases, rentals and imports.
You can always download iTunes 12.8 for previous versions of macOS,
as well as the iTunes application for Windows.
