Getting started with LaTeX on a Mac
This document is intended to get you started with LaTeX on a Macintosh OS X computer as quickly as possible. There are many alternative ways. Here I picked what seemed simplest and fastest. It is difficult to estimate the overall time required because of varying download and installation times. However, your hands-on time should be well below 30 minutes. Try it out now. It will be new in many ways, but you will probably be convinced by its professional layout and the great LaTeX-related software packages in the end.
Step 1: Get the LaTeX environment
This will install all the essentials and many optional LaTeX packages onto your Mac.
Step 2: Get a LaTeX editor
TeXShop is a LaTeX code editor with text highlighting and command autocomplete (Esc key). It explains itself well - watch the movies that come with the v2.14 installer. If you want to do completely without commands get LyX instead. I recommend TeXShop here, since it is fairly easy to use and allows you to dig deeper if you want to.
