Apple has provided developers with the third developer beta for macOS Ventura 13.3 to try out.
Developers enrolled in the beta program can acquire the latest builds via the Apple Developer Center, or by updating hardware already running beta software. Public beta versions typically arrive a short while after their developer counterparts, and are available through the Apple Beta Software Program.
AppleInsider and Apple strongly advise users don’t install beta operating systems, or beta software in general, on to “mission-critical” or primary devices, as there is the 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.
