macOS 10.13 High Sierra is an operating system that was designed and developed by Apple from 2017 to 2018 alongside Apple’s personal computers. The system has been released on September 25, 2017, and was available for Free from Mac App Store, or was preinstalled on currently sold computers. This software gets the last update (10.13.6) on November 12, 2020, and later has been replaced by a newer version of macOS 10.14 Mojave.
macOS High Sierra is the fourteenth major release of macOS. The name “High Sierra” refers to the High Sierra region in California. As with Snow Leopard, Mountain Lion, and El Capitan, the name also alludes to its status as a refinement of its predecessor focused on performance improvements and technical updates rather than user features. Among the apps with notable changes are Photos and Safari.
Apple File System (APFS) replaces HFS Plus as the default file system in macOS. It supports 64‑bit inode numbers, is designed for flash technology, and is designed to make common tasks like duplicating a file and finding the size of a folder’s contents faster.
It also has built‑in encryption, crash‑safe protections, and simplified data backup on the go. macOS High Sierra adds support for High-Efficiency Video Coding (HEVC), with hardware acceleration where available, as well as support for High-Efficiency Image File Format (HEIF).
Safari has a new “Intelligent Tracking Prevention” feature which uses machine learning to block third parties from tracking the user’s actions. Safari can also block auto-playing videos from playing.
Today macOS 10.13 High Sierra is 5 years old!
