The fourth macOS Sonoma 14.2 developer beta is out, with Apple sharing the fresh build with testers alongside RC4 of macOS Ventura 13.6.3 and macOS Monterey 12.7.2.
Developers partaking in the beta program can pick up the latest build by visiting the Apple Developer Center or updating Macs running the beta to the newest build. Public beta versions are generally available via the Apple Beta Software Program not long after the developer versions are released.
The fourth build is number 23C5055b, replacing the third, build 23C5047e.
Reported changes found in the betas have so far included iMessage sticker reactions, a Favorites Apple Music Playlist, collaborative Apple Music playlists, and iMessage Contact Key Verification.
As well as the fourth beta of macOS Sonoma 14.2, Apple has also issued the fourth release candidate of macOS Ventura 13.6.3 and macOS Monterey 12.7.2. These updates largely consist of security fixes and compatibility improvements, rather than introducing new features.
The fourth RC of macOS Ventura 13.6.3 is build 22G433, while the fourth RC of macOS Monterey 12.7.2 is build 21G1971.
AppleInsider and Apple strongly suggest users don't install beta operating systems or other beta software on "mission-critical" or primary devices, as there is the small chance of issues that could result in the loss of data. Testers should instead use secondary or non-essential hardware and ensure they have sufficient backups of their critical data at all times.
