What are web browser cookies, why many users want to clear cookies and how can we delete them on Mac quickly? If you don’t know how to clear cookies on your Mac, you can get detailed steps in this post. We will show you how to delete cookies on Mac in Safari, Chrome, Firefox and Opera web browsers. Before we plunge into details, let’s figure out what are cookies.

What are cookies and what do they do?

Cookies are small text files that save the data of the websites like website preference, your login details, which will speed up the connection to the websites you regularly visit. There are two types of cookies including session cookie and persistent cookie.

Cookies are used in a number of ways:

  • Cookies can be used to store login information for a website you visit frequently. In that way, you don’t have to enter your user name and password each time you visit the site.
  • Another use of cookies especially the persistent cookie is to track items while you visit an online vendor. The cookie can keep track of the items you select while navigating through the different sections until you decide to go to the check out page and purchase them.
  • Cookies can also be used to save information you enter in a form. If there is a problem when you submit the form (if a field that is required is left blank, for example) the cookie can save you some typing and time by entering the rest of the information so that you only have to fill in the field with the problem.

Unfortunately, cookies can also be used by advertisers to track your web surfing habits so as to deliver ads based on your interests. This can be considered as an invasion of your privacy. While disabling cookies in your web browsers may limit the functionality of some websites that rely on them. This may be one of the reasons why you want to leave cookies enabled, but you can also clear cookies on your Mac at any time to protect your privacy. Though cookies are small text files, many cookies can also eat up much Mac space, so removing them can also help you free up Mac space.
