Thanks to Joel for the info:
As some of you know, Garmin has set up a page dedicated to their software for MacOSX since MWSF in January. At the same time a beta mac version of MapSource -- aka Bobcat -- was made public. Over the past month, two other beta's came out and corrected the errors of youth in the first version, and it now is really usable software. Garmin also stated that City Navigator 2008 (Europe and North America) will have mac format maps on DVD . At the moment, even though Bobcat is there, we (currently) go through a Windows converter for maps (a utility provided by Garmin).
Detailed information on the Garmin and mac:
Webupdater which manages updates GPS is available and stable.
POI Loader that allows loading of the points of interest in GPS is available and stable.
MapManager which installs the maps on the mac is available and stable.
MapInstall which allows you to load maps customized to your GPS is available in beta.
