Never update macOS unless you get a new mac and you're forced to
It's true that "point-0" releases should be avoided by people who don't know what they're doing… but by the "point-three" releases, you're missing out on tons of bug fixes and security patches.
The path-to-happiness for most Apple users is "ignore releases between September and October, but otherwise auto-install everything," but that requires too much effort for most people.
