Apple’s latest upgrade in its Mac operating system, known as High Sierra, is out and is available as a free upgrade for users. High Sierra is compatible with all Macs from 2010 onward, as well as with some MacBooks and iMacs released as far back as 2009.
“MacOS High Sierra is an important update that makes the Mac more capable and responsive, while laying the foundation for future innovations,” said Craig Federighi, Apple’s senior vice president of software engineering. “High Sierra introduces new technologies for VR, high-efficiency video streaming, advances in storage technology and more, while apps such as Photos, Safari, Mail and Notes are refined to give users even more reasons to love their Mac.”
While this update does not boast of any stunning changes in Mac’s outward appearance or design, it has some great features that have improved the performance of some core apps and functionality.
There are quite a lot of changes introduced with High Sierra. Apple’s previous file system HFS is now switched with the new APFS file system. APFS runs on 64-bit architecture and is faster and more stable than its previous version. It has built-in encryption and crash safe protection. With APFS everyday operations like copying files and directories have become faster. Apple claims that this change in the system will be able to provide more protection against viruses.
Another app that got a major upgrade is Safari. The app has gotten much faster. It’s ramped up the capability of shielding users against ad tracking and auto-play of videos. Users can set preferences according to websites or ban it completely.
The previous format for videos by Apple was H.264. It’s now being replaced with H.265 format. Also known as High-Efficiency Video Coding, this format can compress files up to 40 percent as compared to its previous version.
Metal, Apple’s advanced graphics technology, has been upgraded to Metal 2. It supports next-generation experiences like machine learning used in speech recognition, natural language processing and computer vision. It also provides external GPU support.
Other than that, there have been changes in the Notes App, VR support and everyday apps like Photos.
