macOS High Sierra, Apple's latest desktop operating system is now available as a free update with powerful new core storage, file system, video and graphics technologies and more.
macOS High Sierra is an important update that makes the Mac more capable and responsive, while laying the foundation for future innovations, said Craig Federighi, Apple's svp of Software Engineering.
The new Apple File System (APFS) ensures more efficient and reliable storage and support for High-Efficiency Video Coding (HEVC) brings stunning 4K video, copying files and directories and other common operations are now nearly instantaneous. And, the advanced data integrity features protects data from power outages and system crashes.
As of now, APFS only supports Mac with flash internal storage, while Fusion and HDD Mac systems support will be available in future update.
HEVC (H.265), a new industry standard enables extremely efficient compression, streaming and playback of 4K video while requiring 40 percent less storage space than current H.264 standard.
H.265 by taking advantage of hardware acceleration feature on new iMac and MacBook Pro, can deliver incredibly faster and power-efficient encoding and playback.
Metal 2, an advanced graphics tech with Core ML supports machine learning (ML) used in speech recognition, natural language processing (NLP), computer vision, and powers virtual reality (VR) content creation, faster performance and more.
Combined with Thunderbolt 3, Mac users now have access to powerful external GPUs. And, the refined API enable developers, like Unity, Epic, Valve, Pixelmator and more accelerate their future apps.
The Core ML developer framework makes it easy to create apps with powerful machine learning that predict, learn and become more intelligent. All of the computation and processing driven through Core ML is done on-device in a way that respects customers' data and privacy.
macOS High Sierra also includes a number of refinements to apps, including Photos, which gets a revamped UI, new editing tools and useful third-party integrations:
- updated, always-on sidebar, new filtering and selection tools make photo organization quick and easy.
- refreshed editing UI includes powerful new editing tools like Curves, for fine-tuning contrast, and Selective Color, for making adjustments to a specific color range.
- Live Photos can now be edited with fun effects, like Loop, Bounce and Long Exposure, and users can also choose a different key photo.
- Photoshop, Pixelmator and other third-party editors can be launched from Photos, with edits saved back to Photos library.
- third-party project extensions from Shutterfly, WhiteWall, Wix, ifolor, Mimeo and Mpix provides access to printing and publishing services from right within the app.
Additional app reninements, including Siri, Safari, Notes and more, including:
- Safari stoping media with audio from automatically playing,
- Reader can automatically open articles in a clean, uncluttered format,
- Intelligent Tracking Prevention in Safari detects and eliminates cookies and other data used by advertisers for cross-site tracking,
- Siri gains more natural voice and learns music preferences, creates custom playlists and answers music trivia when using Apple Music.
- Touch Bar gets new Control Strip options plus an improved color picker and more video controls.
- Notes adds simple tables, allowing a user to type in cells, make edits and move rows and columns.
- Spotlight provides flight status information, including departure and arrival times, delays, gates, terminals and even a map of the flight path.
- Touch Bar on MacBook Pro gets even more Control Strip options.
