LaTeX

LaTeX, which is pronounced «Lah-tech» or «Lay-tech», is a document preparation system for high-quality typesetting. It is most often used for medium-to-large technical or scientific documents but it can be used for almost any form of publishing.

Installation

When installing LaTex, two following options are given to users:

1. Install MacTeX with builtin editor (TexLive) - (3.2GB)
2. Install BasicTeX only (100MB) + your personal LaTeX editor

MacTeX vs BasicTeX

MacTeX includes additional programs such as an editor and a BibTeX reference manager that help users to work with TeX outside of the command line. BasicTeX does not include these GUI programs. The trade-off that comes with using BasicTeX is that you will have to download and install additional packages and programs as the need arises- and BasicTeX is so basic that the need will arise. So, after installing BasicTeX you will be faced with the tasks of installing additional programs and installing missing packages.

MacTex

Since MacTex installs a LaTex editor (TexMaker) already, installing another LaTeX editor is unnecessary.
