Why can't Macs use the RSS feeds?

in CW 2 Maintenance

I wasn't aware, until today, that all of the Mac users in our timebank (and some other timebanks) are unable to use an RSS feed for recent offers/requests.  I would like to know from the developers if this is possible or was it not written in that kind of language.  This RSS feed is terribly important for us right now, until we are able to view the offers/requests chronologically.  I was hoping I could get an explanation so that I can use the explanation in my software tutorials that we give all new members.  Thanks!
