As with any beta release, the update is bound to have bugs, so Apple recommends you only install beta software on a secondary device. It’s also a good idea to make sure you have a current backup, just in case something goes wrong.
But, if you’re okay with the risk, there’s a lot to look forward to in the High Sierra update, even if it’s more of a refresh of last year’s Sierra update.
Apple has made significant improvements to the Photos app, with a revamped user interface and new editing tools; Safari, which can now prevent auto-play videos; and Mail, which now comes with faster search.
There’s also Apple’s new File System, as well as enhancements to Siri, Notes, and Spotlight (which are also integrated in iOS 11). And, for VR developers and enthusiasts, High Sierra will be the first version of MacOS to support virtual reality.
