There was an important note about Office 2011 caught my attention. Interesting, I didn’t know I can view site in writer mode before! There are also some improvements in video and icloud experience, which I don’t really care. The new Safari also has a feature to allow you to view sites in Reader mode. Safari in this version not only becomes much faster (Apple claims it is the fastest desktop browser, I am not sure about this), but also has a feature to stop the most annoying feature on the web: autoplay videos. Important enhancements in the APFS include faster speed in file copy, built-in encryption, crash-safe protections.
Instead of using HFS+ file system, a new file system, Apple File System (APFS), was introduced. There are some nice changes in the new OS. The latest version of Mac OS is called macOS High Sierra.
