Beta is available to anyone who signs up to be part of Apple’s beta testing program
Apple has launched the first public beta roll out of macOS High Sierra for beta testers. This will allow non-developers to download and test the update since its introduction at WWDC earlier this year. Anyone with Apple’s beta testing program can download the update via a software update on the Mac App Store. To be part of the beta testing program, users must sign up through the beta testing page. This will give them access to macOS as well as betas for iOS and tvOS.
Before installing the new OS, it should be noted that this is a beta version of the software and there are some bugs and issues in the system. So it is a good idea to back up the system and / or install the OS on a secondary device. This is a particularly good idea because one of the major changes to macOS High Sierra is a new file system called Apple Filesystem (APFS), which adopts HFS + as the default file system.
The update will bring high-performance video encoding (HEVC) to Macs, including Apple’s next-generation Metal Graphics API, Metal 2. Apps have also been improved. The Photos app offers more ways to edit and organize, while Safari now uses machine learning to remove cross-site tracking data used by advertisers. The browser will turn on Reader mode by default and will prevent video and audio from playing automatically. The new update brings Siri a natural sound with the ability to share iCloud files via links.
