If you meant "latex" specifically:
There are three versions of MacTeX.

Full installation:
  brew cask install mactex

Full installation without bundled applications:
  brew cask install mactex-no-gui

Minimal installation:
  brew cask install basictex

安装： brew cask install basictex；brew cask install latexit
说明：安装mactex会默认安装latexit，但是mactex这个软件太大了，几个G，没有必要建议只安装latexit;但是必须安装brew cask install basictex
