macOS High Sierra is a free operating system from Apple designed for Mac and Macbook Pro computers. It comes after Apple's previous release, called Sierra. This new version brings exciting changes to the table by offering improved performance, a refined look, and lots of brand-new features that make using your Mac or Macbook Pro even more enjoyable.
High Sierra works on both new devices and some older models, so many people can benefit from this update. The software was first announced at Apple's WWDC '17 event as the next big step in operating system technology for Mac users.
High Sierra makes your computer run faster and smoother by introducing new core technologies that boost performance across the board. With improved graphics processors, better data storage solutions, and more responsive design, you can do all your tasks faster than ever before on a Mac or Macbook Pro.
One of the best things about High Sierra is its strong focus on security and user protection. The operating system comes with built-in encryption, simplified data backup options, and crash-safe safeguards to ensure your important files are always secure.
Though High Sierra may look similar to its predecessor at first glance, there's a lot more going on underneath the hood. The operating system is powered by new technologies like Apple File System (APFS), HEVC video coding, and Metal 2 graphics processor, just to name a few. Even the standard apps that come with your Mac or Macbook Pro get an upgrade in performance for better speed and ease of use overall.
