Removing (uninstalling) Palm Desktop for Macintosh: "# Continue through the Software License Agreement windows by clicking on AGREE, the Palm Desktop Installer window appears.Having tried this about six times, I'm reasonably sure there's no such dropdown menu in the current release.
# In the top left corner of the window, click on the dropdown menu and select UNINSTALL. Directly beneath this menu, place a check to select Palm Desktop software.
I did use the Installer's show files option -- the Palm installer puts a horribly long list of gunk in the System Library and elsewhere. No wonder this is such a festering sore.
