macOS High Sierra, released by Apple in September 2017, marked a significant step forward for macOS users, offering a range of features that enhanced both performance and usability. This update was more of a refinement than a complete overhaul, building on the foundation laid by macOS Sierra while introducing new technologies and improvements that paved the way for future advancements.
Core Features and Enhancements
APFS: A Modern File System
One of the standout features of macOS High Sierra was the introduction of the Apple File System (APFS). Designed to replace the older HFS+, APFS brought faster file operations, improved data integrity, and better optimization for solid-state drives (SSDs). This change significantly enhanced the speed and reliability of file management, making tasks like copying files and booting up the system noticeably faster.
Graphics and VR Support
With macOS High Sierra, Apple introduced Metal 2, the next iteration of its graphics API. Metal 2 improved rendering performance and efficiency, supporting more complex and demanding applications. Additionally, this update brought virtual reality (VR) development support to the Mac for the first time, allowing developers to create immersive experiences using platforms like HTC Vive.
Photos App Improvements
The Photos app saw substantial upgrades in High Sierra. Users could enjoy better organization tools, enhanced editing capabilities, and seamless integration with third-party apps. New features like the persistent sidebar and more advanced search functionalities made it easier to manage extensive photo libraries.
Safari Upgrades
macOS High Sierra introduced key enhancements to Safari, focusing on privacy and user experience. The browser added Intelligent Tracking Prevention to reduce cross-site tracking by advertisers, ensuring a more private browsing experience. Additionally, Safari gained the ability to block auto-playing videos on websites, a much-welcomed feature for many users.
Mail and Notes Improvements
Apple’s native Mail app was optimized to use less storage, saving significant space on users' devices. The Notes app also received new functionality, including the ability to pin important notes for quick access and the addition of tables for better organization.
Performance and Compatibility
macOS High Sierra was compatible with a wide range of Mac models, dating back to late 2009. This broad support ensured that many users could benefit from the update without needing to invest in new hardware. The system also retained a focus on energy efficiency, making it a reliable choice for laptops and desktops alike.
Lasting Impact
While macOS High Sierra has since been succeeded by newer macOS versions, its introduction of APFS and support for modern graphics technologies set the stage for the advancements that followed. It was a transitional release that balanced innovation with stability, ensuring users could enjoy a smoother, more efficient computing experience.
Whether you're revisiting High Sierra for legacy applications or exploring its features for the first time, this macOS version remains a noteworthy chapter in Apple's software history.
