Manage cookies and website data
Websites often store cookies and other data on your Mac. This data may include information that you have provided, such as your name, email address, and preferences. This data helps websites identify you when you return so the site can provide services for you and show information that might be of interest to you.
By default, Safari accepts cookies and website data only from websites you visit. This helps prevent certain advertisers from storing data on your Mac. You can change options in Safari preferences so that Safari always accepts or always blocks cookies and other website data.
Important: Changing your cookie preferences or removing cookies and website data in Safari may change or remove them in other apps, including Dashboard.
Choose Safari > Preferences, click Privacy, then do any of the following:
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.
Ask websites not to track you: Some websites keep track of your browsing activities when they serve you content, which enables them to tailor what they present to you. You can have Safari ask sites and their third party content providers (including advertisers) not to track you.
With this option turned on, each time Safari fetches content from a website, Safari adds a request not to track you, but it’s up to the website to honor this request.
