Apple issues first developer beta of macOS 11.2 [U]
Following Tuesday's iOS 14.4, iPadOS 14.4, watchOS 7.3 and tvOS 14.4 beta releases, Apple has provided developers with the first test version of macOS Big Sur 11.2.
Apple offers downloads of its betas through the Apple Developer Center, for participants in its developer test program, though hardware already running beta software can also receive an over-the-air update. Public beta variants usually arrive a short time after developer versions, and can be accessed through the Apple Beta Software Program website.
Apple did not provide any detailed release notes beyond the usual bug fixes, but if any new features exist in macOS 11.2 they will be discovered soon. Apple has been optimizing their latest Macs running the M1 processor.
AppleInsider, and Apple itself, highly recommend 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.
Update, Dec. 17, 2020: Apple has released a public beta version of macOS 11.2.
