These are my personal macOS preferences with install scripts for configuring a machine as fast as possible.
Clone or download into ~, modify the crap out of them (they're just my prefs and yours are probably different), then run .dotfiles/scripts/bootstrap - this will symlink the appropriate files (anything with a .symlink extension) to your user folder. Everything else is imported or sourced from the .dotfiles directory.
Run .dotfiles/macos/set-defaults.sh to set some sane defaults for your computer (definitely change the computer name though unless your name is Bryn).
After that, run .dotfiles/scripts/install to install a decent set of apps via homebrew.
The structure and many of the preferences came from @holman's dotfiles with a smattering of macOS preferences from @mathiasbynens' dotfiles as well. Shout out to them for making it easy for an idiot like me to hit the ground running.
