Apple issues second Release Candidate betas for macOS 12.1 & iOS 15.2

The newest builds can be downloaded via the Apple Developer Center for those enrolled in the test program, or via an over-the-air update on devices running the beta software. The public version of these releases are also available via the Apple Beta Software Program website.

For macOS Monterey 12.1, this is the sixth beta in the testing cycle and the second Release Candidate beta. The build number increased from 21C51 to 21C52.

The second iOS 15.2 Release Candidate beta is the sixth beta in the testing cycle, and it is only available for iPhone 13 models. The build number increased from 19C56 to 19C57.

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 make sure there are sufficient backups of important data before updating.
