It is this Monday, September 25, 2017 that Apple deploys the update of its operating system for computers. Called macOS High Sierra, it notably includes a new file storage management and a more fluid handling of videos in ultra-high resolution.
The main change from the update to macOS High Sierra, although fundamental, will not be visible since it is no more and no less than its new storage technology, the Apple File System (APFS). Dj is optional in macOS Sierra, this time it is offered by default. Also featured in the latest versions of iOS, it is particularly expected to provide improved performance, security and reliability of data. More than ever, it is therefore necessary to make a backup of your personal data before updating macOS, in case a problem occurs.
Apple also announces that macOS High Sierra supports the HEVC (H.265) video standard which allows streaming and playback of ultra-high definition video files while being up to 40% more compact than with the H standard. .264 current. Note that macOS High Sierra also inaugurates support for the creation of virtual reality content, allowing developers to create games and virtual reality content in 3D immersive.
Among the new announcements concerning applications, users will benefit in particular from improved applications, such as Photos (new sidebar, more “memories”, advanced editing tools), Safari (faster, but also more energy efficient, with less advertising campaign and the possibility of customizing the presentation and the options linked to any site) and Mail (new search tool). Note that it also becomes possible to share an iCloud storage plan with the whole family, up to 2 TB of data.
To update macOS for free, go to the Mac App Store, start the download then install macOS High Sierra and be patient. This procedure is compatible with all computers already running macOS Sierra, potentially all MacBook and iMacs put on sale since the end of 2009.
