Apple releases the fourth public beta for macOS 10.15 Catalina

On Thursday, Apple released the fourth public beta version of its macOS Catalina operating systems, giving those in the public beta test program a chance to test out the latest Mac features before their release in the fall.


The fifth developer beta for macOS 10.15 Catalina had been released yesterday for those participating in the Developer Beta program. Other updated betas for iOS 13, iPadOS 13, watchOS 6, and tvOS 13 had showed up earlier this week.

Public participants of Apple's beta tester program can download the newest public beta of Catalina from the Apple Beta Software Program site. Users who have an older version of the beta can upgrade through the Software Update preferences panel.

Both AppleInsider and Apple itself strongly recommends users don't install the betas on to "mission-critical" or primary devices, as there is the remote possibility of data loss or other issues. Instead, testers should install betas onto secondary or non-essential devices, and to make sure there are sufficient backups of important data before updating.
