To change your default RSS reader application from Safari, do this:
- Install the RSS reader you want to use on your Mac. I use NetNewsWire, but there are plenty of others to choose from.
- Launch Safari.
- Choose Safari > Preferences
- Click the RSS tab.
- Choose the reader application you want to use from the Default RSS reader pop-up menu.
Set your default news reader app in Safari’s RSS preference tab.
I follow over 100 news and blog RSS feeds every day, so I wanted an application that gave me more control over how I organize and view articles than Safari offered. Thanks to Mac OS X’s preference for setting a default news reader, I can do just that — even if the preference setting is in Safari instead of System Preferences.
