Table of contents

Cookies. You’ve definitely heard of them. You’ve probably lost count of how many times a website has asked you to accept them, and that’s only today! You’ve probably also been advised, “try clearing your cookies”, on multiple occasions as you wrestle with some annoying IT problem.


But what are cookies and how do you delete them? Let’s find out more so you know how and why you should do it.  

Why it is important to clear cookies

To understand why we need to delete cookies, it’s important to understand what cookies actually are.


Cookies are tiny lines of text dropped on your internet browser by a server hosting any website you visit. They allow websites to remember who you are - so they recognize you on your next visit and show you more relevant web content.


Though cookies serve the common good for website marketing teams, they have the potential to be a real headache for you. Here’s why:

  • Cookies track and store your user data. This is obviously not something you want if you mind your online privacy.
  • Cookies help websites manipulate advertising and pricing strategies - and you never know whether the deal you’re shown is actually the best available.
  • Cookies become outdated over time. This is why some websites show you invalid usernames and passwords.

If you feel like your browsing is not as smooth as it used to be, cookies could be to blame. So, here is how to delete cookies on your Mac.

How to clear cookies on your Mac

There’s always a simple way to delete cookies no matter which browser you prefer to use on your Mac.


Here’s how to clear cookies from Safari, Google Chrome, and Firefox on your Mac.

What’s more to know about cookies?

Are cookies a security risk?

While third-party cookies might raise a few eyebrows over privacy, browser cookies don’t pose you any risks in terms of viruses or malware. They only contain information you yourself share with a website. They can’t be used to access your hard drive or hack into any other personal information.

Should I accept cookies in the first place?

In general, cookies exist not to ruin but enhance your web browsing experience. For example, cookies are why websites remember items you’ve left in your shopping cart to checkout at a later time. For this reason, accepting cookies is rather beneficial.

What will I lose if I delete cookies?

Deleting cookies will affect three aspects of your web experience - your online accounts, your settings and how you’re tracked.


Your online accounts

  • You will be logged out of any websites you were logged in to


Your website settings

  • Previously visited websites will no longer recognise you
  • Any website preferences you had will reset
  • Any items you had in your shopping cart will need to be added again


How you’re tracked

  • The ads you see online might not reflect your past browsing history
  • When you do a search in your web browser, the results will be un-customized

What happens if I don’t allow cookies?

Cookies can be important to a good internet experience. In fact, you may not be able to connect to a website without allowing them. So, blanket blocking all cookies is probably a bad idea, as you may miss out on a wide range of website functionalities.


How often should I clear cookies?

The answer will depend on the device you use. If it’s a public computer, then you should delete cookies and browsing history as soon as your session ends. If it’s your personal device, then you can clear cookies after visiting some shady websites or noticing any drops in browser performance. The recommended frequency for clearing cookies is either every month or every few months.
