I am sure this has been discussed before but I would appreciate any views on what people think is the best software to run on an imac to take data from your weather station. I have a Davis Vantage Pro. I am trying Weathercat but will have to pay for a licance soon. Are there any good free options that do a simple job as I don't need anything very fancy. I am aware of Cumulus but I can't seem to find a mac friendly version?
