OS X Mavericks – 10

macOS High Sierra – 10.13

macOS High Sierra (version 10.13), first released on September 25, 2017, is the fourteenth major release of OS X, renamed macOS, Apple’s desktop and server operating system for Macintosh computers. It is the successor to macOS Sierra and the predecceesor of macOS Mojave. Following the California landmark-based naming scheme introduced with Mac OS X Mavericks, High Sierra was named after the High Sierra region of the Sierra Nevada mountain range. High Sierra is an update of MacOS which focuses mostly on back-end developments and a higher level of user security. As such, this operating system lays a foundation for future upgrades. In essence, High Sierra took what was good with Sierra and developed it into a more comprehensive software. High Sierra emphasizes the already-existing benefits of MacOS previous system, Sierra. There are few bells and whistles, but the changes are noticeable and positive. The Apple file system is the most significant feature it brought. It enables the storage and encryption of a large number of files. Thus, it boosts performance and helps manage device memory issues. Apple also introduced new formats for video and photos in this version. These formats compress data - that’s a benefit as files can get huge with ever-rising resolutions. They added support for virtual reality headsets as well. Besides that, when it comes to Safari, Mac search engine, there are some notable improvements with the update. The users can now control annoying auto-play videos, prevent tracking, and more. There are also notification controls, and you will experience a boost in performance, too.

The most noticeable changes took place in Apple’s Photo App, though. It went through a total revamp both visually in its interface and terms of tools and functions available. Many other discreet changes happened all over the system.
