Apple has provided developers with the second build of macOS 11.5 for testing as part of the current beta cycle.
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. Public beta releases usually arrive a short time later via the Apple Beta Software Program website.
The first beta for macOS 11.5 surfaced on May 19, alongside the first betas of iOS 14.7, iPadOS 14.7, tvOS 14.7, and watchOS 7.6. That release occurred while macOS 11.4 was available as a release candidate, ahead of its public release.
So far, there doesn't appear to be any major changes to the operating system's features in the beta, with it more likely to be a bug fix, performance improvement, and compatibility release. Given the upcoming WWDC event on June 7, Apple is also going to be motivated to keep all of its big alterations for the next major milestone release of macOS.
Both AppleInsider and Apple strongly suggest users avoid installing betas on to "mission-critical" or primary devices, due to the potential for data loss or other issues. Instead, the recommendation is to install betas onto secondary or non-essential devices, and to ensure there are sufficient backups of important data before making any major changes.
