Today Apple previewed the next major revision to its macOS operating system, macOS High Sierra. Some improvements to the operating system include key speed enhancements and refinements to Safari, Photos, Search, and graphics. Also Apple will change the disk formatting default from Hierarchical File System (HFS) to Apple File System (APFS). A Developer Preview version will be available immediately for registered Apple Developers, with a Public Beta expected in July.
The developer preview of macOS High Sierra is available to Mac Developer Program members starting today. To help make macOS even better, Apple is also providing a macOS Public Beta Program, which gives customers early access to macOS High Sierra and invites them to try out the release and submit their feedback. Mac users can participate in the Apple Beta Software Program for macOS Sierra this July and download the final version for free from the Mac App Store this fall.
In order to download and test out macOS High Sierra, you must be a registered and paid member of the Apple Developer Program. A Public Beta is expected to release sometime later this Summer, with general availability in the Fall.
Please note, our rules prohibit discussion of the Developer Beta, but will allow discussion of the Public Beta when it is available.
