In the Safari sidebar, you can see links from people you follow on Twitter, links shared by your LinkedIn connections, and articles from web feeds you subscribe to.
To add shared links and feeds, do any of the following:
Add your Twitter and LinkedIn accounts in Internet Accounts preferences.
Subscribe to articles from websites in Safari.
To view shared links and feeds, click the Sidebar button in the Safari toolbar, then click the Shared Links button .
Search your shared links: Enter text in the search field above the list of links. You may have to scroll up to see the search field.
View the next shared story: Keep scrolling when you reach the end of a shared story—no need to click the next shared link in the sidebar.
Hide shared links from an account: Click Subscriptions at the bottom of the sidebar, then deselect the checkbox for the account.
Remove a web feed subscription: Click Subscriptions at the bottom of the sidebar, then click the Remove button next to the feed in the sidebar.
