At the time of this writing, not a single software maker in the computer market has software for Mac OS X that directly imports Navionics charts from media card for permanent use on the computer.
If any Mac OS X developers out there are looking for a million dollar idea, here it is!
You may purchase the charting software MacENC and then also purchase an X-Traverse hosted Navionics chart collection (ex. Navionics 50XG for Mac is popular). That combination will allow you to use Navionics charts on your Mac computer.
There is no special cross-promotional deal linking Navionics media card products with the equivalent product download from X-Traverse; in other words, they are separate purchases.
Charts download via X-Traverse app for Mac to hard drive folders of your choice -- MacENC and GPSNavX do not perform the download directly.
