Well, it is kinda forced update, as it turned out that the only thing one can do with GanttProject.app on the latest Mac OSX Mountain Lion is to move it to the trash. As people normally don't find it quite useful, I spent a few days trying to sign GanttProject.app properly. Now it is done, and GP 2.5.5 runs on Mountain Lion fine.
