Apple has rolled out the macOS 12.2 beta update to public testers in its beta program, just a day after it became available to developers. As 9to5Mac notes, the OS comes with a new Music app that Apple had rebuilt as a full native application. Apple introduced macOS' dedicated Music app back in 2019, but it kept some iTunes elements for some parts of it, which means it still displays web content within the app.
Based on what 9to5Mac has seen, macOS 12.2 beta uses AppKit, the framework needed to give applications a native interface. There won't be a big difference in looks, but the new app will apparently work faster. Searching for songs within Music, for instance, will appear more quickly because the results will be displayed on a native interface, while scrolling will feel smoother and trackpad gestures will feel more responsive.
In addition to a brand new Music app, macOS 12.2 will also make scrolling in Safari smoother for the 14-and-16-inch MacBook Pro models that support refresh rates of up to 120Hz. To test out macOS 12.2, you'll have to download and install the macOS Developer Beta Access Utility. You'll then be able to access the latest beta update in the Software Update section of System Preferences.
