I'm a long-time PC user as well as a Garmin user and only recently I bought my first Mac... a MacBook Air that I intend to use while I'm traveling by bike. Because of the comments here about BaseCamp being better on the Mac than on the PC, I downloaded and installed it on my Mac and now I'm trying to get everything working on the Mac sort of the way I had it on the PC (but better). I can't figure out how to move things from the PC to the Mac. I'm not even talking about (yet) things like my saved POI's and routes. My immediate frustration is how to get my main NA (Lifetime) map to install on the Mac. Yes, it's visible in BaseCamp but ONLY WHEN my Zumo 660 is connected to the Mac, but on my PC I have the map installed to BOTH my GPS and my computer. Older versions of Garmin Express allowed changing the installation parameters so that a map could be installed to BOTH the GPS unit and computer, but unfortunately the newest versions do not. Installing instead to ONLY the GPS unit. On the PC I got MapInstall which still DOES allow installation of maps to both locations. MapInstall on the Mac however doesn't give that option and comes up with a message saying that no unlocked maps could be found. So, how do I get my map onto the Mac? Thanks!
