There are many ways to install LaTeX on different operating systems, and documenting all of them is beyond the scope of this repo. As I said in the README, I personally use a distribution called MacTeX. In my opinion, it’s the best way to ensure that you have all the required dependencies. Since you’re on Mac, you should consider it. You can also read about the differences between MacTeX and BasicTeX on the MacTeX site.
