Really Simple Syndication, or “RSS,” refers to an alternative way of viewing a webpage. The term RSS is used interchangeably with feed, news feed, RSS feed, and XML feed.
Websites that change frequently—news sites, for example—often have RSS pages. An RSS page presents the titles of new and recent articles in a list, showing part or all of each article’s content so you can see what the article is about. A link to the full article is included.
When you go to a website that has an RSS page, you see an RSS icon at the right end of the address field in Safari.
Many websites have more than one RSS feed. For example, a newspaper’s website may have separate feeds for news, sports, and entertainment articles.
You can find RSS pages by searching websites or by clicking the open-book icon in Safari and selecting All RSS Feeds in the sidebar on the left.
You can set up a screen saver to display content from RSS pages when your computer is idle.
