Doing search and rescue has my teams using GPSon a regular basis and I was recently put into a command position tracking search teams. I have always been a devout Mac user but could not find software or even decent maps to use with my Garmin GPS's. Wish I had looked here first, unfortunately just sucked up and go a toshiba with VISTA
Bad thing is I had called Garmin Customer Service and they said that they had NO COMPATIBLE SOFTWARE for MAC
