Here's a somewhat dated example of such a setup: https://github.com/memco/dotfiles https://github.com/memco/dotfiles. Basically, you just need the install.sh if all you care about is macOS preferences, but you can also add in something like the brewfile so that you can also install your apps. My brewfile leverages MAS so that I can install stuff from the app store in addition to what's available via brew. I haven't automated app preferences, but macOS and apps are just a clone, `./install.sh && brew bundle --file Brewfile` away.
