MacTeX is a free utility created by the MacTeX TeXnical working group of the TeX Users Group (TUG).
MacTeX is a Mac OS X component of the TeX Collection DVD, the reference edition of TeX distributed by TeX User Groups across the world.
The reference can be accessed on Mac OS X, Windows, GNU/Linux, various BSD Unix systems, and most other computer architectures.
MacTeX includes two components: MacTeX-2008 and MacTeXtras. MacTeX-2008 is an install package which installs everything needed to run TeX on Mac OS X. The package uses Apple's standard installer and the installation takes four to eight minutes and is automatic.
MacTeXtras is basically a collection of optional extras: Spell Checkers, Additional Front Ends, Documentation and Showcase items.
What's New in This Release: [ read full changelog ]
· MacTeX-2012 installs updated versions of the GUI applications that were already in MacTeX-2011.
· MacTeX has optional packages to install two font collections (Latin Modern and TeX Gyre) in /Library/Fonts; these TeX fonts are already in TeX Live, but installing them in /Library/Fonts makes them available to standard Macintosh applications like Adobe Illustrator. By default, these fonts are not installed.
· MacTeX installs the latest version of Ghostscript, 9.05, and an updated "Convert" from ImageMagick 6.7.6-9. These packages are self-contained; MacTeX installs no libraries in /usr/local/lib.
· In previous years, MacTeX was provided as a zip file. The install package was rewritten this year using Apple's modern PackageMaker, so this year's MacTeX-2012.pkg is a flat file which doesn't have to be zipped for a server or unzipped after downloading. The package is signed so it can be installed on Mountain Lion.
