MacOS Catalina Public Beta 4 Released
Apple has issued the fourth public beta version of MacOS Catalina 10.15 for Mac users who are enrolled in the public beta testing program for system software.
As usual, MacOS Catalina Public Beta 4 matches the build of MacOS Catalina developer beta 5.
Users who are currently running MacOS Catalina public beta can find public beta 4 available to download now from the Software Update system preference panel.
MacOS Catalina features some interesting new capabilities and changes, including a feature called Sidecar that allows an iPad to serve as a secondary display to a Mac, a new screen saver, the dissolution of iTunes into three separate media apps, notable updates to built-in apps including Photos, Reminders, and Notes, abandoning of 32-bit app support, stricter security measures for apps and the system software itself, and more.
Any Mac user can decide to participate in the public beta testing programs and install MacOS Catalina public beta onto a MacOS Catalina compatible Mac, but this is generally only recommended for advanced Mac users because beta system software is notoriously prone to bugs and problems compared to final builds.
Aside from the Mac, iOS 13 and iPadOS 13 public beta 4 are also available as updates, and similarly to the Mac public beta program any interested advanced iOS or iPadOS user can install iPadOS 13 public beta or install iOS 13 public beta on iPhone. And if you want to beta test software for Apple TV you can do that too by installing tvOS 13 public beta.
While no precise release date is known, Apple has said that MacOS Catalina, iOS 13, iPadOS 13, tvOS 13, and watchOS 6 will all be released this fall.
