Open Source Objective C TeX/LaTeX Software for Mac

BibDesk is a graphical bibTeX bibliography manager for Mac OS X.

TeXShop is a TeX previewer for Mac OS X, written in Cocoa. Since pdf is a native file format on OS X, TeXShop uses "pdftex" and "pdflatex" rather than "tex" and "latex" to typeset in its default configuration; these programs in the standard TeX Live distribution of TeX produce pdf output instead of dvi output. TeXShop uses TeX Live, a standard distribution of Tex programs maintained by the TeX Users Group (TUG) for Mac OS X, Windows, Linux, and various other Unix machines. The distribution includes tex, latex, dvips, tex fonts, cyrillic fonts, and virtually all other programs and supporting files commonly used in the TeX world. The most recent version of this distribution is maintained for the Mac by the MacTeX TeXnical Working Group of the TeX Users Group and available under the "Obtaining" tab.

Excalibur is a TeX/LaTeX aware spelling checker. It will also spell check plain text documents.

The Mac TeX Toolbox provides an umbrella for TeX related development for Mac OS X: discussions, pointers to libraries and other support for open source TeX development on Mac OS X.

TexConsole allows you to translate your Tex source into a PDF document. It does not depend on a certain Tex distribution. It also shows you the log file in case of an error or the PDF Document in case of success. Multiple builds are also supported.
