So Andrus, Going back to a conversation we had many years ago (and I'm too lazy to find the thread), we had talked about the OS X version of Cayenne Modeler and how I had checked in some changes which move the About/Preferences/etc menus to where they belonged for an OS X application. It turns out if you run CM using the Maven plugin, those menu options are not available. I suppose the best way to fix this is to check if running as a .app and then move the menu items, otherwise leave them alone?
