Manage cookies and website data in Safari on Mac
You can change options in Safari preferences so that Safari always accepts or always blocks cookies and website data.
In the Safari app on your Mac, choose Safari > Preferences, click Privacy, then do any of the following:
Prevent trackers from using cookies and website data to track you: Select “Prevent cross-site tracking.”
Cookies and website data are deleted unless you visit and interact with the trackers’ websites.
Always block cookies: Select “Block all cookies.”
Websites, third parties, and advertisers can’t store cookies and other data on your Mac. This may prevent some websites from working properly.
Remove stored cookies and data: Click Manage Website Data, select one or more websites, then click Remove or Remove All.
Removing the data may reduce tracking, but may also log you out of websites or change website behavior.
See which websites store cookies or data: Click Manage Website Data.
