Safari in Mac OS X El Capitan features Pinned Sites to keep your favorite websites open and active. And there are a couple of ways to do the pinning.
The sites you pin will stay active in the background, pinned to the left side of your tab bar. Assuming you've launched Safari and have a website loaded, you can:
- Click and drag on the tab you want to pin.
- Slide it to the left side of the tab bar.
The tab will stay pinned and will sport a favicon to let you know which site it is. To unpin it, click the favicon and slide it to the right.
You can also right click/control-click/two finger click on a tab. A contextual menu will pop up with options to Pin Tab, Close Tab, Close Other Tabs, or Move Tab to New Window.
Select Pin Tab and the tab will slide to the left with your other pinned tabs. To unpin it, slide to the left or right-click again and select Unpin Tab (if you want it keep the tab open) or Close Tab (if you want to close the tab entirely).
Pinned Sites stay in place, even when you open a new Safari window or quit and reopen Safari. When you click a link to another website from a Pinned Site, the other website opens in a new tab. Your Pinned Site always shows the website you pinned.
OS X El Capitan is available as a free update from the Mac App Store. The operating system upgrade supports all Macs introduced in 2009 and later, and some models introduced in 2007 and 2008.
