SeeGEDCOMX is a minimalist genealogy program for the Macintosh, started before MacOS X made minimalism fashionable. Originally a browser application for GEDCOM files, it has become a much more general application. You can now use it to create a family history from scratch, to maintain an existing family history stored as a GEDCOM document, or simply to browse your GEDCOM documents and downloads. And I believe it’s the only genealogy application with AppleScript support.
Major Changes: Expiration date moved out to June 2006, “Group By Change Date” feature to allow you to easily find where you were last working, To Do List improvements, and various bug fixes.
