This review was originally posted on VersionTracker.com. I fully agree.
"This software is written in Java. It is very slow. Still needs many features. Davis does not spend much time, effort, or money on the Mac version of Weatherstation, even though the same investment goes into the equipment you must buy. The interface is reminiscent of 1980s or earlier design and the program is buggy. Sometimes it will not boot up part of the program at all or crashes and takes down the system (yes, it is one of the very few programs I've seen that will occasionally crash OS X, requiring a re-start)."
Davis makes an excellent weather station, but the software for mac is terrible. It does work but crudely. It is so bad, Davis shoud offer it free if at all.
