1 Start Private Browsing

In Safari, choose File > New Private Window. A new window with a dark gray address and search field will open. None of the sites you visit in this window will be remembered, and websites you visit will be asked not to track you.

2 Close iCloud Tabs

Left a page open on another Mac or iOS device that uses your iCloud account? Simply click the “Show all tabs” button in Safari’s toolbar, then scroll down to iCloud Tabs, put the pointer over the one to close, then click the X next to it.

3 Clear a period from History

To remove a large amount of activity from your history, choose History > Clear History, then choose a duration. When you click Clear History, sites visited, cookies and cached data from that period are cleared from both your Mac and iCloud.

4 Clear specific History items

To clear the record of a specific page, choose History > Show History, then right-click on the page’s row and choose Remove. To clear several at once, hold ç and click each in turn to select them all, then press ∫ to delete.

5 Clear a site’s cookies

In Safari > Preferences, click the Privacy tab, then the Details button halfway down the window. Scroll through the list of sites to find the one you want (or enter part of its name in the search box), select it, then click Remove.

6 Hide frequently visited sites

Safari’s Favorites view shows sites you visit often, as well as those you’ve explicitly added to it. To remove one of them, right-click its icon and choose Remove, or just drag its icon out of the group until the pointer shows an X, then let go.
