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.
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.
The latest TeXShop release, version 3, requires System 10.7 (Lion). 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. 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. Both of these versions are available on this site.
TeXShop is distributed under the GPL public license, and thus free.

The following process will trigger the process for a few people but probably not you. Create a source window using the menu command "New". Enter one or two lines of text and then save the file using the menu command "Save As". Quit TeXShop and restart it again. Open the new source file. The file's name will be added to TeXShop's "Window" menu, but the corresponding source window will not appear. It seems that TeXShop has created a source file which it cannot display. This is an alarming bug.
Here is the good news. There is nothing wrong with the file; it contains the correct text and can easily be opened using a trick. Even better, the bug only occurs if the user has selected "Syntax Color expl3 Code" in the TeXShop Source Window. This menu is a toggle which turns expl3 coloring on or off. When a window first opens, it is off. The only problem is that TeXShop has a hidden preference which turns the item on by default when windows are first opened:
defaults write TeXShop expl3SyntaxColoring YES
Only users who set this hidden preference are likely to see the bug.
The bug has nothing to do with TeXShop's file saving code. It is a bug in TeXShop's syntax coloring code. When opening a source file, TeXShop syntax colors the source just before making the window visible. If the syntax coloring fails, the window is never made visible. TeXShop 5.32 fixes one step in the expl3 syntax coloring routine. After that, the routine does not fail and all windows open correctly.
