Instructions in this article apply to the Safari web browser for macOS, OS X, and iOS devices.

To remove your browsing history, cookies, caches, and other website data from Safari on your Mac and across any synchronized devices:

  1. Select Safari > Clear History from the menu bar at the top of the Safari screen.

You can also clear all history by selecting History > Clear History. You have the same options here: the last hour, today, today and yesterday, and all history. There is no confirmation, and the deletion is immediate.
