Garmin Support for OSX
As I wrote here Garmin promised that they would release OSX versions of their software that is MapSource and POI Loader, well finally a year after they initially said something about it they have released a beta of POI Loader for Mac.
Lucky me, who does not have a GPS which support POI Loader….. So I will still be waiting for MapSource on OSX…..
As for howto to do stuff with your GPS on OSX look here; Peter Hilton (yes the guy from Hilton Harbour) have some neat tricks here.
