Apple has launched Public Beta for MacOS
Apple has launched MacOS High Sierra public beta for testing. The OS update is now available for download for those who want to check it out.
The High Sierra is still in beta version as such some bugs should be anticipated. Downloading the update can cause system breakage or file loss. It is advisable you run it on a secondary system or back up your files first.
The update has the new APFS file system, which replaces HFS+ as the new default. In existing betas of High Sierra there's been an option to stick with HFS+ when installing, but otherwise your drive will be in-place upgraded to APFS.
It's best you put High Sierra in a separate partition for testing, to keep your existing files and folders untouched if you are not comfortable with that.
Apple has upgraded millions of iPhones to APFS with little hassle, so if you have standard Apple hardware in your computer it's probably a relatively safe procedure.
The High Sierra features Metal 2 graphics API, which supports VR and external GPUs, the new HEVC and HEIF video and image formats. There are also user-facing improvements to Photos, Siri and Safari.
