TeXShop is distributed under the GPL public license, and thus free. Both of these versions are available on this site. Users with systems 10.2 or 10.3 should use TeXShop 1.43, and users with systems 10.0 and 10.1 should use TeXShop 1.19. An earlier version of TeXShop, version 2, is also maintained and requires System 10.4 (Tiger), although System 10.5 (Leopard) is strongly recommended because it fixes several important bugs in Apple's PDFKit code, extensively used in TeXShop.

The latest TeXShop release, version 3, requires System 10.7 (Lion). 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. The distribution includes tex, latex, dvips, tex fonts, cyrillic fonts, and virtually all other programs and supporting files commonly used in the TeX world. 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. 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.

TeXShop is a TeX previewer for OS X, written in Cocoa. If you prefer to install them system-wide, you can put them in the corresponding texmf/tex folder within your LaTeX installation (the location of this installation on OS X varies depending on which LaTeX distribution you used).
