Ron,

Currently the OCENS WeatherNet, GRIB Explorer, and MetMapper softwares are only PC (they run fine under VMware or Parallels). There is a program that run natively on the on the Mac - MacWX. This is the equivalent of our WeatherNet and can be downloaded via our support page. For viewing GRIB files you will need a viewer - a good one would be the GPSNAVX or MacENC software from GPNAVX.com.

Our email service/software does work on Mac or PC.
