TeXShop is a Tex previewer for Mac OS X. For more information, click on The link below downloads a "LocalTeX" preference pane. This pane is a complement to the "TeX Dist" preference pane installed by MacTeX, which allows a user to select the active TeX distribution. The local pane allows individual users to override the choice made for all users by the TeX Dist pane, and to select distributions installed on a thumb drive, external hard disk, or home directory. It does not modify any data used by the TeX Dist pane and works on Mountain Lion and above, including Yosemite. The download includes the LocalTeX pane, documentation, and full source code. Ghostscript 9.15 was released on September 22, 2014. Below is an install package for Ghostscript 9.15. The package will work on Leopard and above, for Intel or PPC. In case it causes trouble, install the previous version. Ghostscript 9.15 fixes the bugs in 9.14 which caused us to use Ghostscript 9.10 in MacTeX 2014.

Below is an install package for Ghostscript 9.10. This package is part of MacTeX-2014.

Below is an install package for Ghostscript 9.07. This package is part of MacTeX-2013. Here is a paper about making a small TeX distribution for Mac OS X. The distribution, BasicTeX, is available at tug.org/mactex/morepackages.


Two other small Cocoa programs for Mac OS X are available: Below are the slides from a talk given at OIMT on May 19, 2012. You may also want to access: Notes from a lecture at Bend: I recently taught
