Install to Make macOS High Sierra Better
Do you want to help Apple make macOS High Sierra better this fall for everyone? If so, this is a good reason to install the High Sierra beta on your Mac.
You can send feedback to Apple to let them know how you like new features, how they fit into your workflow and if they are something that should be in the final version of macOS 10.13.
When you tell Apple about a bug in the developer or public beta, you can help the company find solutions to issues and problems that the company might otherwise miss until a full release to the public.
