I spoke with Battery Park Software, makers of GedWise (MobileGenealogy.com’s GedWise page), and later this year, or early next year, they will be releasing a Mac OS X version of their GedWise Palm OS genealogy software.
What this means is that you will be able to install and update GedWise on your Palm OS-based PDA through Mac OS X. Currently they have a beta version of GedWise for Linux, and then they are moving to Mac OS X. This is being built as a cross-platform application which is good news for Mac OS X Palm users.
When this is released, it will join My Roots as the only other active PDA-based genealogy application with Mac OS X support.
