The fourth public beta builds of the new operating system can be downloaded via the Apple Beta Software Program website by users signed up to take part in the testing program. The public beta versions of the operating systems usually trail the release of the developer beta by a short period of time. Signing up at the website offers users access to macOS, iOS, and tvOS beta downloads.
The upcoming new operating system offers new apps and new technology for developers, and replaces the venerable iTunes app with Apple Music, Apple Podcasts and the Apple TV apps. The new OS also allows Mac users to use their iPad as a second display or graphics tablet.
As usual, MacTrast and Apple both warn users to never install betas on your daily driver iPhone, iPad, Apple TV, Apple Watch or Mac computer, instead only install it on a device set aside for testing purposes.
We also strongly advise that Mac users perform a Time Machine or other type of backup before installing the macOS Catalina beta.
