Apple today seeded the third beta of an upcoming macOS High Sierra 10.13.6 update to developers and public beta testers for testing purposes, one week after seeding the second 10.13.6 beta.

The new macOS High Sierra 10.13.6 beta can be downloaded through the Software Update mechanism in the Mac App Store with the proper profile installed.

We don't yet know what improvements the sixth update to macOS High Sierra will bring, but it likely focuses on bug fixes and performance improvements for issues that were not able to be addressed in macOS High Sierra 10.13.5.

No feature changes were discovered in the first two macOS High Sierra 10.13.6 betas, but we'll update this post if new features or notable bug fixes are discovered in the third.

Work on macOS High Sierra is wrapping up, with Apple now shifting focus to the next-generation version of macOS, macOS 10.14, which was unveiled at the Worldwide Developers Conference on June 4.

10.13.5 issues, File Vault is not working, Dashboard exits back to home screen after accessing. Eversince Tim Cook took over, so many major issues on each and every update they release.
You mean like Display Profiles permanently changing themselves in Tiger or Home folders + user data being deleted in Snow Leopard? Oh wait.

Seriously. I've been using Macs since the early '90s. There have always, always been bugs.
