Weatherdisplay and Met Office WOW site

I’m having trouble getting my Mac setup to access the Met Office WOW site. Brian has asked me to run the cronwow program in a terminal window, but, unless I’m being terribly thick, there is no instance of the cronwow program on my Mac installation.

Has anyomne else had the issue?

I’m not sure why, but it now seems to be working. In the intervening period, I signed up to Wunderground and that worked first time.
