Today, in addition to iOS 13.3.1 and iPadOS 13.3.1 developer preview Beta, Apple also released the first developer beta of macOS Catalina 10.15.3. This update is one week away from the official update of macOS Catalina 10.15.2.
Registered developers need to download the macOS Catalina beta configuration file from the Apple Developer Center. Users can download a new beta version of macOS Catalina using Software Update in System Preferences.
In the official version of macOS Catalina 10.15.2, Apple has fixed a large number of Bugs and enhanced the stability of the system. At the same time, the iTunes remote control also supports remote control of the Music and Video apps on your Mac through your iPhone or iPad.
macOS Catalina splits the iTunes app into music, podcast, and TV apps, and no longer supports 32-bit apps and games. macOS Catalina also introduced a new Sidecar feature that turns the iPad into a Mac’s second display.
