Today, Apple held its big September hardware event, where it announced a trio of new iPhones, an Apple Watch that offers cellular connectivity, and an Apple TV that supports 4K and HDR streaming. Afterward, it released GM seeds for the next versions of the operating systems that those products use, including iOS 11, watchOS 4, and tvOS 11.
Oddly enough, macOS 10.13 High Sierra was left off of the list, and while Apple publicly announced a September 19 release date for the other three, macOS wasn't mentioned at all during the keynote.
Now, the firm has updated the High Sierra listing on its website to say that it will be available on September 25. If you're currently running the beta, you'll likely see the GM seed in about a week.
One of the key features of High Sierra will be the Apple File System (APFS), which is built on a 64-bit architecture and is meant to be more responsive and secure. It also brings support for the next generation of Apple's graphics engine, called Metal 2, along with virtual reality support and more.
