Apple's major MacOS High Sierra update is finally available for Macs

This file system is claimed to be much more secure and protective against cyber crimes and illegal security breaches.

Apple has released the latest version of its desktop operating system, the aptly-named macOS High Sierra, and you can go download it right now.

The new video technology in High Sierra called HEVC (High Efficiency Video Coding, also known as H.265) means "videos stream better and take up less space on your Mac, while preserving the same visual quality".

The main change in macOS High Sierra is the switch to a new file system - the Apple File System (APFS) - which, although fundamental, may not be the most immediately visible change. Metal 2 powers virtual reality content creation, faster performance and more.

Supported machines include all Macs from 2010 and later. This version of the OS is the updated variant of the predecessor macOS Sierra.

Apple first unveiled the new system in June, and has spent the past few months perfecting features like an improvement to Siri's voice and music recommendations within Siri.

But here's a quick rundown of some key new features.

Honeypreet's ex-husband Vishwas Gupta had also claimed that he saw the two having sex in Ram Rahim's private chamber. He was annoyed and slammed the Dera chief. "Ram Rahim made us play a game similar to "Bigg Boss" in his cave".

High Efficiency Image File Format (HEIF) and High Efficiency Video Coding (HEVC) are powerful new standards-based technologies for storing and delivering images and audiovisual media.

Apple's macOS High Sierra will also make it faster to find your files and emails, help you automatically organize and edit your photos, and mute autoplay videos on Apple's Safari browser among other improvements.

The new codec can compress video up to 40% more than the existing H.264 standard. Metal 2 supports next-generation experiences like machine learning used in speech recognition, natural language processing and computer vision. But of course, it still has a file system and that's getting a whole new architecture with this update.

It's always a good idea to make a backup of important files and apps before committing to a new software update, but it's an absolute necessity this time.

Other than that, there are some improvements that users will spot.

Apple's final note is that macOS High Sierra is available as a free update starting today from the Mac App Store. macOS High Sierra supports all Macs introduced in late 2009 or later.
