Apple releases fourth macOS Big Sur beta to developers

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.

Apple has already released betas for the other four operating systems of this generation, with iPadOS 14 and iOS 14 surfacing first on Tuesday before a secondary release for tvOS 14 and watchOS 7.

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.
