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.
