Apple releases macOS 10.15.2 beta 3 to developers

A new third beta of macOS Catalina 10.15.2 is now available to developers as an over the air updated for devices enrolled in the Apple Developer Center. While not yet available, a public beta update will be issued shortly for users participating in the Apple Beta Software Program.

This third beta comes after the second one was released on November 13. Apple's developer notes for that release reported that the chief update was to specific networking issues. Apple added the key website top-level domains .dev and .app to its implementation of the HTTP Strict Transport Security system to help safe browsing.

The prior first beta, released November 7, had more updates including additional eGPU support, improvements to Photos, and a fix for an Apple Pay bug.

At this stage, it is unknown what changes Apple has made in this third beta.

Both AppleInsider and Apple itself strongly recommend 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.
