The latest version of “the world’s most advanced desktop operating system” is here. Apple launched macOS Catalina today, a free update that introduces Apple Arcade, a game subscription service, and a trio of apps that replaces the classic iTunes: Apple Music, Apple Podcasts, and Apple TV apps.

Catalina also adds a Sidecar feature that extends Mac desktops to iPads as a secondary display or tablet input device, as well as Mac Catalyst, a new technology that makes it easier for third-party developers to bring iPad apps to Mac.

Three all-new apps — Apple Music, Apple Podcasts and Apple TV— replace iTunes and make it easy and fun to discover and enjoy music, TV shows, movies and podcasts on Mac. The new Music app is fast and features over 50 million songs, playlists and music videos. Users will have access to their entire music library and new music can still be purchased from the iTunes Store.
