The MacTeX Technical Working Group (mTWG) was formed in Hawaii in July 2003 at TUG 2003: the Silver Anniversary -- 25 years! -- of TeX, the 24th Annual Meeting and Conference of the TeX Users Group (TUG). Its goal is to work on action items that would enhance current and future development of TeX on Mac OS X. Apple Computer Inc. was a sponsor at TUG 2003 and provided computers, wireless networking, and technical support that enabled TUG to have its first remote live presentation from the Netherlands to an audience in Hawaii.
