One of the coolest features of Mac OS X Tiger is its RSS Screen Saver. When your screen saver goes into action, news feeds from the site you select are displayed onscreen, along with a brief intro to the article.

To change Tiger’s default screen saver to use the RSS feed, follow these steps:

  • Open System Preferences
  • Select the Desktop & Screen Saver’s preference panel
  • Click the Screen Saver tab
  • In the list of available Screen Savers to the left, select “RSS Visualizer”
  • After selecting RSS Visualizer, you’ll see a demo of the RSS screen saver in the display to the right

By default, Tiger’s RSS screen saver calls up news items from Apple’s Hot News RSS feed. If you want to select a different screen saver:

  • Click the Options button
  • A sheet slides out, displaying a list of other “pre-ordained” RSS sites which you can choose from
  • Select a feed (for example, the “O’Reilly Network” feed)
  • Click the Done button
  • To see what the screen saver looks like, click the Test button

Now when the screen saver jumps into action, you’ll see news items fed to you from the O’Reilly Network of sites, including the Mac DevCenter.

Note: Your computer must have a Quartz Extreme-compatible graphics card for the RSS Visualizer to even appear in the list. If you don’t see this item in the list of available Screen Savers, your Mac won’t be able to use this feature.
