Announced earlier this year at the company’s Worldwide Developers Conference event, Apple today released the macOS High Sierra update to all compatible devices across the globe. Like previous updates before it, macOS High Sierra is available as a free download from the Mac App Store. Don’t expect a major redesign or anything as some of the biggest changes have been made under the hood.

Supported machines include all Macs from 2010 and later. There are some iMac and MacBook models from 2009 that are capable of upgrading to macOS High Sierra.

Apple chose to make some of the more significant changes under the hood. High Sierra has a new file system called Apple File System. It also brings support for more efficient photo and video standards, HEIF and HEVC respectively. The new video standard efficiently handles 4K video without taking up too much storage on the machine.

Other than that, there are some improvements that users will spot. This includes an improved Siri experience, new editing tools in the Photos app, changes in the way Safari handles autoplaying videos and ad tracking, and more.

Apple is now rolling out macOS High Sierra to compatible machines across the globe. You’ll soon receive an over-the-air update notification on your device informing you that a major software update is available.
