I am running the latest versions of Basecamp, Mapinstaller, and Mapmanager, as well as the latest version of the E32 maps. Everything worked very well, and it was seamless. I did purchase the Windows version of the E32 maps, and then converted it for Mac, as I wanted to have a Mapsource version of the E32 Maps as well. I was/am a little hesitant to completely use the Mac/Basecamp side, as I am very use to Mapsource. Basecamp for Mac still crashes a bit, and won't send data straight to my Zumo, but for the last Baja trip I did, and the current trip into the Sierra Nevada that I am on, Basecamp worked, and I see myself using the Mac side and Basecamp more and more in the future. I actually prefer sending the necessary maps to the GPS with Mapinstaller, and the latest version of the E32 maps played well with everything.
