  • You can clear the cookies on a Mac computer through a Safari browser in a few quick steps, whether you block or clear them all wholesale, or pick and choose which sites you wish to stop tracking you and storing your data.
  • An HTTP cookie is a small text file stored on your Mac that helps websites quickly identify you when you visit.
  • Cookies are intended to make your online experience efficient and customized to your preferences, but they can also lead to coercive delivery of ads and make it easier to track your web history and to obtain your data.

Internet cookies weren’t created with sinister intent, but the way they work bothers some people nonetheless. An HTTP cookie is a short text file created by a website but stored on your computer that contains a bit of information about you.

The most common cookies include your login data (username and password) that allows for quick access to an account (think Netflix or PayPal), a list of your past search history that can make a shopping experience more efficient (Amazon), or the images featured on a certain website you visit frequently, allowing for quicker loading the next time you click through.

Cookies are the reason online ads are often oddly specific to you; they are one source that helps advertisers tailor the advertisements served to you based on your past web history. And they also make your potentially sensitive data, like a password, more readily accessible to other parties.

The good news is that clearing cookies on a Safari, a Mac computer’s default browser, is a quick process, and you can also manage how you are tracked in the future from individual sites.
