Apple Seeds Seventh Beta of macOS High Sierra to Developers [Update: Public Beta Available]

Apple today seeded the seventh beta of an upcoming macOS High Sierra update to developers for testing purposes, a week after seeding the sixth beta and more than two months after introducing the new software at the 2017 Worldwide Developers Conference.

The seventh beta of macOS High Sierra can be downloaded from the Apple Developer Center or over-the-air using the Software Update mechanism in the Mac App Store.

macOS High Sierra builds on features first introduced in macOS Sierra, focusing on new storage, video, and graphics technology. It brings a new Apple File System (APFS), High Efficiency Video Codec (HEVC), and an updated version of Metal with support for VR and external GPUs.


Several apps are gaining new features in macOS High Sierra. The Photos app features a new sidebar to make it easier to access editing tools and albums, and there are new filters and editing options like Curves and Selective Color. Photos also supports external editing apps like Photoshop and Pixelmator, saving changes made in those apps back to Photos, and it interfaces with new third-party printing services.

Safari is gaining speed enhancements, an option to prevent autoplay videos, and a new feature that cuts down on cross-site data tracking. Siri in macOS High Sierra has expanded music capabilities and a new, more natural voice, and Spotlight supports flight status information. There are also improvements to iCloud, FaceTime, Messages, and Notes.

macOS High Sierra is available for both registered developers and public beta testers and will see a few more weeks of testing ahead of its expected fall public release.

Update: Apple has also released a sixth public beta of macOS High Sierra for public beta testers.
