Apple has announced macOS High Sierra, the latest release of the world’s desktop operating system, is now available as a free update. All Macs from 2010 and later are compatible with the update, and some MacBooks and iMacs released as far back as 2009 can also run it. The total size of this update is around 4.8 GB
With macOS High Sierra, Mac users gain powerful new core storage, video and graphics technologies. A new file system ensures more efficient and reliable storage, and support for High-Efficiency Video Coding (HEVC) brings stunning 4K video at lower file sizes. Metal 2 powers virtual reality content creation, faster performance and more. The Core ML developer framework makes it easy to create apps with powerful machine learning that predict, learn and become more intelligent. macOS High Sierra also includes a number of refinements to the apps Mac users enjoy everyday, including Photos and Safari.
Apple File System (APFS)
- APFS is a new, advanced storage architecture providing an extensible foundation to support new features and future storage technologies on the Mac.
- APFS brings support for the latest high-capacity storage devices and delivers enhanced performance, security and reliability.
- With APFS, common operations such as copying files and directories are nearly instantaneous.
- Data is protected from power outages and system crashes thanks to advanced data integrity features.
- APFS currently supports every Mac with all‑flash internal storage — support for Fusion and HDD Mac systems will be available in a future update.
High-Efficiency Video Coding (HEVC) Support
- HEVC (H.265) is a new industry standard that enables extremely efficient compression, streaming and playback of video.
- HEVC enables users to watch 4K video files at full quality, while requiring 40 percent less storage space than the current H.264 standard.1
- With HEVC, Apple is enabling high-quality 4K video streaming on networks where only HD streaming was previously possible.2
- Hardware acceleration on the new iMac and MacBook Pro delivers incredibly fast and power-efficient HEVC encoding and playback.
- Developers like Adobe, Blackmagic Design, GoPro and more are joining Apple in adopting HEVC.
- Metal is Apple’s advanced graphics technology and the fastest, most efficient way to tap into GPU power on the Mac.
- Metal 2 supports next-generation experiences like machine learning used in speech recognition, natural language processing and computer vision.
- Metal 2 features a refined API and improved performance that’s helping developers, including Unity, Epic, Valve, Pixelmator and more, accelerate their future apps.
- With the combination of Thunderbolt 3 and Metal 2, the most demanding Mac users can now access powerful external GPUs.
- With Core ML, Apple brings the power of machine learning to all Apple developers, enabling the creation of entirely new kinds of apps.
- Core ML takes full advantage of Metal and Accelerate, delivering incredible power, speed and efficiency to machine learning operations such as computer vision, natural language and support for convolutional and recurrent neural networks.
- All of the computation and processing driven through Core ML is done on-device in a way that respects customers’ data and privacy.
- Developers are already using Core ML to enhance apps like Pixelmator Pro, which uses machine learning to detect and understand various features within images and create intelligent editing solutions.
