Apple has released macOS Catalina 10.15 beta 2 to developers for testing. The build number is 19A487l.
Run the macOS Developer Beta Access Utility to download the latest macOS beta. As new macOS betas become available you will receive a notification and can install them from the Software Update pane in System Preferences.
With macOS Catalina, Apple is replacing iTunes with new Apple Music, Apple Podcasts and Apple TV apps. A new Sidecar feature enables users to extend their Mac desktop by using their iPad as a second display or as a high-precision input device. New security features keep users better protected and Voice Control lets users control their Mac entirely with their voice. You can learn more about macOS Catalina here.
