How to make your garmin gps work on mac

I have had much success by following the instructions of this link.

I usually clear my gps of tracks before going on a hike and then download the new tracks to my Mac using GPSBabel+ as described in the link above. I open the track in Google Earth and work with it there and finally export it to the web look at my walk around Town Lake in Austin:

If I ever get to play with RFID tags...
