Please read only the first two sections below if you are a new user installing TeXShop for the first time. If you are upgrading from a previous version, read these two and the next four sections. If you are familiar with TeXShop and want to customize it, read the remaining sections.
When TeXShop first runs, it places default preference items, macros, templates, and typesetting engines in the user's library folder. If the program is later updated, these preference items, macros, etc. are not modified because the user may have edited them. In a few cases, important changes were made in the default items; these changes are listed here so users of previous versions can modify preferences and templates appropriately.
TeXShop has a few hidden preferences for power users. Such users can also modify program behavior by installing various plist files. Details are provided below.
New versions of TeXShop sometimes require additional menu items and other interface components. These new items appear in English even when the rest of the interface has been localized for another language. If users write me with appropriate translations, I will immediately make the changes in the copy of TeXShop on my web site. Write koch@math.uoregon.edu.
