I have been reading my news on my MAC for some time with an app called GRUML. It was ok but now REEDER for the Mac is out and I really like it. Reeder is a really fast, full featured news reader. Simple and clean, gets the job done. It is also my goto news reader on my iPhone.
Only feature missing is the ability to email a full article including media. The app is still in beta so I hope they add that soon.
