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.
