Can anyone help me on this one .I'm looking for a program like Ozi explorer that can be used to upload and dowmload Waypoints to my iMac (Arrives this week I'm told).

I can run Ozi with boot camp/Windows XP. However I don't want Microsoft anywhere near my iMac and am looking for a program that supports a Magellan eXplorist XL. It connects via USB. I don't want to use the GPS when driving just when I'm hillwalking so I want a program that can handle Topgraphic maps

Any thoughts
