During the ongoing WWDC 2019 keynote, Apple unveiled the macOS 10.15, and it has decided to call the latest update macOS Catalina. Along with a host of new features, the latest version of the operating system has also done away with iTunes, which has now been broken into other apps. Instead of adding more features into iTunes, it was perhaps more sensible to break it up into different apps but this can be confusing for some consumers. However, those who were used to iTunes will find that the latest update does end up making things a little more flexible, even though there are more apps that users will need to recognize.

News apps that have been introduced in place of iTunes include Apple Podcasts, Apple Music, and Apple TV. Of course, these aren’t new apps per se, but the latest versions have more features. The Podcast app will make use of machine learning to make it easier to search for shows. The TV app has added support for 4K HDR video and also includes Atmos content.
