High Sierra introduced three pivotal technologies that fundamentally changed how Macs handle data and graphics:
Apple File System (APFS): Replacing the decades-old HFS+, APFS is a 64-bit architecture optimized for modern flash storage and SSDs. It enables nearly instantaneous file duplication through "cloning" (pointing to existing data until it's modified) and features built-in encryption and crash-safe protections.
Metal 2: This low-level graphics API provides 10x better draw call throughput compared to its predecessor. It handles demanding window animations—like Mission Control—more smoothly and introduces support for machine learning, virtual reality (VR), and external GPUs (eGPUs).
High Efficiency Video Coding (HEVC/H.265): A modern video standard that compresses video files up to 40% more than H.264 without losing quality. This allows for higher-quality 4K video streaming and storage on smaller drives. Version 10.13.6 Highlights
The 10.13.6 update was the final major release of High Sierra, specifically adding:
AirPlay 2 for iTunes: Support for multi-room audio, allowing you to play and sync music across multiple AirPlay 2-enabled speakers throughout your home simultaneously.
Performance Fixes: It addressed critical bugs in the Photos and Mail apps and resolved a "thermal management" issue in 2018 MacBook Pro models that caused excessive processor throttling. Refined Native Apps
High Sierra brought significant improvements to daily-use applications:
Safari 11: Introduced "Intelligent Tracking Prevention" to block advertisers from following users across sites. It also added a feature to block autoplaying videos on a per-site basis.
Photos: Revamped with a persistent sidebar, advanced editing tools like Curves and Selective Color, and the ability to sync "People" identification across all iCloud devices.
Mail: Optimized for efficiency, the Mail app uses 35% less storage space due to improved compression techniques. System Requirements Best Features of macOS High Sierra
