Apple has moved on to the third beta round for macOS Ventura 13.1, with developers now able to download a fresh build.
New betas can be acquired from the Apple Developer Center by developers signed up for Apple's test program, or via an over-the-air update for hardware already running beta software. Public betas generally appear soon after the developer versions, and are downloaded through the Apple Beta Software Program website.
The third macOS Ventura 13.1 beta build is number 22C5050e, replacing the second, build 22C5044e.
Apple has also released macOS 11.7.2 and macOS 12.6.2 Release Candidate betas. These updates could release alongside macOS 13.1 with patches for vulnerabilities and other bugs.
Both AppleInsider and Apple itself 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 to make sure they have sufficient backups of their important data at all times.
