BaseCamp 4.4.3
The first time I installed it on my iMac, I could not remove or get around the splash page. I removed it and reinstalled it. It worked like a charm, but it could not read or detect the internal map on the Garmin 600 Montana. I exited the software and now all I get is a window that says “BaseCamp quit unexpectedly.” I loaded BaseCamp on a PC. It works great. Something is indeed broke in the software for the Mac.
