Source: macOS is now fully baked with macOS High SierraApple's APFS file system will be the default in the new version, bringing its superior performance and robustness to the desktop Mac, months after Apple made the switch on the iPhone.
Safari is adding a new intelligent tracking feature that will block trackers so that sites such as Amazon will no longer advertise the products you already bought on every site you visit. The new Safari will also block auto-playing video.
What’s New in macOS High Sierra
With macOS High Sierra, you can create incredible virtual reality experiences on Mac. Metal 2 boosts performance even further and lets you move beyond just graphics. Core ML provides easy integration of machine learning models into your app. Photos Project Extensions let users access your app or service from within the Photos app. Swift 4 brings efficiency and stability to your code. And you can now design richer web experiences that will run in Safari thanks to additional web standards support from WebKit.
Metal 2
Metal provides near-direct access to the graphics processing unit (GPU), enabling you to maximize the graphics and compute potential of your macOS apps. And now, Metal 2 further boosts performance by letting the GPU take more control of the rendering pipeline. And Metal Performance Shaders comes to Mac helping your app to accelerate much more than just graphics. It also offers enhanced developer tools that make it even easier to debug, optimize, and deploy apps that use Metal. Learn more about Metal
VR on Mac
macOS High Sierra gives developers and content creators the ability to create stunning video and 3D content using the whole new level of interactivity that VR provides. With the power to harness External Graphics and the HTC Vive VR headset, content creators can use apps such as Final Cut Pro X, SteamVR, Epic Unreal 4 Editor, and Unity Editor to create immersive 360° video and advanced 3D content.
External GPU Support
macOS High Sierra brings support for external graphics processors to the Mac for the first time, enabling you to develop and test demanding graphical applications, including VR content creation, on any Mac with Thunderbolt 3 connectivity. Learn more about the External Graphics Development Kit
Core ML
Take advantage of the same foundational machine learning technology used across Apple platforms and services, including Siri, Maps, QuickType, and Camera. Core ML provides easy integration of machine learning models to enable your apps to learn, predict, and become more intelligent with just a few lines of code. Learn more about Core ML
Swift 4
Swift 4 builds on the strengths of Swift 3, delivering greater robustness and stability, providing source code compatibility with Swift 3.1, making improvements to the standard library, and adding features like smart key paths and serialization, all while shortening build times and reducing the size of app binaries. Learn more about Swift
Photos Project Extensions
Let users access your app or service from directly within the Photos app to create print products, websites, slideshows, and more from their photo libraries. Bring your project features into Photos by adding a new extension to your app which users will be able to quickly discover through the targeted Mac App Store link. By leveraging the built in intelligence of Photos with the full suite of native macOS APIs, there is no end to the creative projects you can bring to Photos users.
WebKit
WebKit is the Apple-led open source browser engine that delivers state-of-the-art web technology to Safari. In macOS High Sierra, WebKit adds new performance optimizations and delivers additional web standards support that enable developers to create richer experiences in Safari.
Apple File System
The Apple File System (APFS) is a modern and secure file system, optimized for responsiveness on Flash/SSD storage, and designed for extensibility and data integrity across macOS, iOS, tvOS, and watchOS. Make sure apps are compatible with the new default file system. To learn more, see Apple File System Guide.
HEVC
The next-generation of standards-based video compression technology, High Efficiency Video Coding (HEVC), provides up to 40% better compression than H.264 at the same visual quality. With support built into AV Foundation on macOS High Sierra and iOS 11, it’s the next essential technology for storing and delivering media.
