TeXShop is a TeX previewer for 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; these programs in the standard teTeX distribution of TeX produce PDF output instead of DVI output.
- The LaTeX hyperref package adds active links and URL's to PDF documents. Many are under author control, but the package automatically links table of contents items to the starts of chapters and sections, and links reference items to the corresponding bibliography entries.
- TeXShop has a hidden preference setting to control the "ColorIndex" tool, as requested by Murray
- OS X 10.7 or later
