macOS readme
I was poking some other people I know who do macOS-y stuff, and it sounds like the os comes with basically everything already installed
for our purposes, it's just making sure they have git, mysql, and pip
looking at our dependencies, we don't actually still need ldap (I've kept it in there because I would eventually like to support multiple auth types for easy deployment at other schools), our 'new' CAS package doesn't seem to libsasl...
...redis is only required for production...
...and I'm pretty sure that the jpeg handling library got put in there for either gravatar or the social media packages to deal with scaling profile pics
but yeah... for those docs, describe a bit about homebrew, make sure they have that installed already if they don't, and then see how the installation and setup goes with the dependencies!
