macOS 10.13 High Sierra - Everything you need to know!

The Mac operating system macOS High Sierra with version number 10.13 was released by Apple in September 2017. Before that, there was a test phase in which Beta versions have been tested and improved; this started in June 2017 with the WWDC17. Although macOS 10.13 High Sierra introduced a few innovations and improved some system content, it was not a completely renewed Mac operating system. As the name itself suggests, this builds on the previous system and extends it a bit - that was macOS 10.12 Sierra. Newly introduced were APFS, HEVC, HEIF and improvements for some apps.

What's new in macOS 10.13 High Sierra?

One of the biggest changes in fall 2017 was that with the new system for Apple computers, the APFS file system was set as the standard for SSD storage. It was previously introduced with macOS 10.12 Sierra but not set as the default. The expansion to fusion drives also came with it macOS 10.14 Mojave. So macOS High Sierra is a kind of intermediate stage between the introduction of Apple's own file system and the end of 32-bit applications. Details can be found here: Apple File System – APFS file system.

with the previous system the voice assistant Siri also came to the Mac. She now got a more natural voice and from autumn 2017 it was possible to choose whether queries could be entered by voice or by typing. In addition, it was now possible to set more individually which apps and content Siri was actually allowed to use. Speaking of Apps: The new system made it possible for the first time to use tables in the Notes app and to pin individual notes to make them easier to find. Changes that are indispensable today.

Image and video content also received a boost. The so-called High Efficiency Video Coding made it possible to encode and decode video content in HEVC format. In addition, the handling of the then relatively new codec H.265 was made possible - as well as the handling of MPEG-H Part 2. With regard to photos and images, the HEVC counterpart was introduced: HEIC. For details on how to use and convert HEIC photos on iPhone, see here: Turn on/off HEIC format for photos on iPhone (+ convert on Mac).

Safari always gets a few additional functions and uses. macOS High Sierra introduced autoplay content blocking. The Messages app has been restricted to iMessage, so AIM and Hello belonged to the past. In the Mail app, on the other hand, the toolbar and the search function have been improved. The Photos app has also got a few more features for editing photos. A new sidebar has also been added for better navigation. Last but not least, it became possible to import content from the iCloud Drive via the Finder to share.
