AppleInsider and Apple strongly recommends that users do not install beta operating systems or beta software on hardware they consider “critical” or primarily used. Instead, they should keep backups of their data and try to use secondary hardware that is less maintenance intensive.
For regular users who want a less risky experience, Apple usually releases the public beta version of its updates shortly after the developer counterpart. A more combat-hardened version of the update, with potentially fewer bugs or issues, this is the version that interested public should try, not the developer build.
