Apple introduced macOS High Sierra at the 2017 Worldwide Developers Conference in June. macOS High Sierra, as the name suggests, is a follow-up to macOS Sierra and is largely designed to improve on macOS Sierra through major under-the-hood updates and a handful of outward-facing changes.
With macOS High Sierra, Apple says it's focusing on the fundamentals: data, video, and graphics. High Sierra is about deep technologies that provide a platform for future innovation while also introducing new technologies to make the Mac more reliable, capable, and responsive.
A more modern file system, Apple File System (APFS), is the new default in macOS High Sierra. APFS is safe, secure, and optimized for modern storage systems like solid state drives. It introduces features like native encryption, safe document saves, stable snapshots, and crash protection. APFS is ultra responsive and brings major performance improvements for Macs.
High Sierra includes High Efficiency Video Encoding (HEVC, aka H.265), which preserves better detail and color while also introducing much improved compression compared to H.264. HEVC software encoding is available for all Macs in High Sierra, but newer models include HEVC hardware acceleration.
Along with a new Apple File System, macOS High Sierra introduces Metal 2, the next-generation version of Apple's Metal graphics API. Metal offers up to 10x better draw call throughput improvements like driver optimizations, indirect argument buffers, sampler arrays, resource heaps, and more. The Mac's window server uses Metal 2 optimizations to make window animations like Mission Control much smoother.
Metal 2 brings support for machine learning, external GPUs, and VR content creation. Apple is providing an external GPU development kit for developers and it is working with Valve, Unity, and Unreal to bring VR creation tools to Mac. Support for eGPUs was introduced in the 10.13.4 update.
In addition to new technologies, there are improvements to several existing apps. Photos has a new persistent side view to make it easier to find what you're looking for, along with new editing tools for Curves and Selective Color. Facial recognition is improved and syncs across devices, while expanded integration with third-party apps is available. New options for editing Live Photos have been introduced, and Memories have been expanded to encompass more categories.
Safari includes a new autoplay blocking feature for videos, along with Intelligent Tracking Prevention to protect your privacy and a new always-on option for Safari Reader. Search in Mail has been improved, and Mail storage has been optimized to take up 35 percent less space. iCloud Drive file sharing and iCloud storage family plans have also been added.
