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.
- Version 3.65 again works on OS X 10.7 Lion and 10.8 Mountain Lion, and thus on all versions of Mac OS from OS X 10.7 Lion to nacOS 10.12 Sierra.
- I omitted the QTKit framework, and made AVKit and AVFoundation optional. The AV frameworks aren't available on OS X 10.7 Lion and 10.8 Mountain Lion, hence the crash of 3.64 on these systems. Demo movies will only play on OS X 10.9
- OS X 10.7 or later
