Apple releases fourth macOS Big Sur beta to developers
Rounding out its set of betas for the milestone operating systems, Apple has provided developers with a fourth build of macOS Big Sur for testing.
The latest betas and configuration profiles can be downloaded from the Apple Developer Center, with subsequent changes available as over-the-air updates on enrolled devices.
For macOS Big Sur, or macOS 11, Apple's main priority for the release is compatibility with Apple Silicon along with Intel processors. Other improvements are naturally included for both processor types, such as design elements within Safari and Messages becoming a Mac Catalyst app.
AppleInsider, and Apple itself, strongly suggest users don't install betas on to "mission-critical" or primary devices, due to the potential for data loss or other issues. It is instead recommended to install betas onto secondary or non-essential devices, and to ensure there are sufficient backups of important data beforehand.
