Summary

Apple macOS High Sierra (version 10.13), released on September 25, 2017, served as a significant evolutionary step for Apple's desktop operating system, focusing primarily on performance enhancements and underlying technological advancements rather than a plethora of new user-facing features. Key strengths included the adoption of the Apple File System (APFS), which brought considerable speed improvements to file operations on SSDs, and the introduction of Metal 2, significantly boosting graphics performance and enabling new capabilities like VR content creation. Safari also received notable upgrades, including Intelligent Tracking Prevention for enhanced privacy and improved power efficiency. The Photos app saw a substantial overhaul with new editing tools and organizational features, and HEVC support allowed for more efficient handling of 4K video.

However, High Sierra was not without its initial challenges. A critical root access vulnerability was discovered shortly after its release, though Apple promptly issued a patch. Other early issues included a WindowServer memory leak and DisplayLink compatibility problems, which were subsequently addressed.

The operating system maintained broad compatibility with Mac models dating back to late 2009, extending the lifespan of many older machines. However, official support for macOS High Sierra concluded on November 12, 2020. This means the OS no longer receives security updates, bug fixes, or direct technical support from Apple, making it increasingly vulnerable to modern security threats.

Recommendations: For users still running macOS High Sierra, an upgrade to a newer, supported macOS version is strongly recommended for security and compatibility reasons. If hardware limitations prevent an official upgrade, community-driven solutions like Open Core Legacy Patcher can be explored, though these come with their own considerations. For those unable to upgrade, it is crucial to employ robust third-party security measures, use up-to-date web browsers, and exercise extreme caution with software installations and online activities.
