Hot on the heels of Monday's slate of beta software releases, Apple on Tuesday issued a third beta version of macOS 10.13.1 High Sierra to developers for testing.

The latest macOS High Sierra beta, build 17B42a, appears to contain only minor bug fixes and performance improvements, according to Apple's release notes.

Like the recent iOS 11.1 and watchOS 4.1 builds, today's macOS High Sierra release offers support for new emoji characters accessible in Messages and other apps.

Apple last updated macOS High Sierra earlier this month with a supplemental release designed to patch critical Disk Utility and Keychain vulnerabilities. The update also fixed a mail deletion issue in Mail and a graphical bug seen when using Adobe InDesign.

Apple's next-generation Mac operating system debuted in September with marquee features like the new Apple File System (APFS), support for Metal 2 graphics, H.265 integration, an improved Safari experience and more.

Developers can access macOS 10.13.1 High Sierra beta 3 by visiting Apple's developer portal.
