Apple previewed macOS High Sierra on June 5, 2017, the latest version of the world’s most advanced desktop operating system, delivering new core storage, video, and graphics technologies that pave the way for future innovation on the Mac. macOS High Sierra offers an all-new file system, support for High-Efficiency Video Coding (HEVC) and an update to Metal, Apple’s advanced graphics technology that powers everything from machine learning to virtual reality content creation. macOS High Sierra also includes some refinements to the apps Mac users enjoy every day, including Photos, Safari and Mail.
macOS High Sierra brings new storage, video and graphics technologies to the Mac.
“macOS High Sierra delivers important forward-looking technologies and new opportunities for developers wanting to tap into the power of machine learning and create immersive VR content on the Mac,” said Craig Federighi, Apple’s senior vice president of Software Engineering. “The core technology innovations in macOS High Sierra, combined with our advances in hardware, will continue to push the Mac forward in exciting new ways.”
Powerful New System Technologies
Apple File System
Apple File System (APFS) features enhanced performance, security, and reliability of data and provides a foundation for future storage innovations. An advanced architecture optimized for today’s massive storage technologies, APFS makes standard operations such as copying files and directories instantaneous, helps protect data from power outages and system crashes and keeps files safe and secure with native encryption. macOS High Sierra also maintains complete read-and-write compatibility with previously formatted HFS drives and data and is designed to accommodate future advancements in storage technology.
Metal 2 unleashes even more GPU power, accelerating graphics and computation for pro content creation, gaming, machine learning and more.
High-Efficiency Video Coding
Support for industry-standard HEVC (H.265) enables video streaming and playback of 4K video files at an incredible quality that is also up to 40 percent smaller than with the current H.264 standard.1 With HEVC, Apple is enabling high-quality video streaming on networks where only HD streaming was previously possible, while hardware acceleration on the new iMac and MacBook Pro deliver incredibly fast and power-efficient HEVC encoding and editing.
