Rick will answer more, but you cannot use the Navionics card reader with a Mac (though at one time a driver was supposedly in process). You can only use the Navionics charts intended for Mac use purchased and downloadable from X-Traverse. In other words, if you have a plotter that uses Navionics cards and want to use Navionics charts on your Mac, you must buy another copy.

So is there is still no way to run my Navionics charts on my Mac? other then paying again, for a down load. I already paid to much for a CF chip for my chart plotter.
