How to clear cookies on Mac in Safari, Chrome & Firefox

Internet browsing is an important part of our daily lives. We use our browsers for work, communication, and entertainment. If you frequently visit the same websites, you may have noticed that they grow more personalized over time. It is because of cookies. 

However, have you ever wondered what cookies are and whether they should be stored? Let’s get straight to the point — they shouldn’t, and it is safer to remove them. So, here’s a handy guide on clearing cookies on Mac. 

What are cookies on Mac

Cookies are bits of information sent from websites you visit to your browser. These tiny pieces of specific data contain information about your online behavior, which allows websites to tailor your browsing experience based on individual preferences. Cookies also allow you to stay logged in on the website even if you close the tab.

As web servers have no memory to store cookies, they are instead saved to your Mac. Some of them get erased when you close your browser, others (permanent cookies) exist on your hard drive until you remember to remove them. 

Here comes the obvious question: should you clear cookies on Mac? The answer is yes because cookies can slow down your browser and devour quite a lot of storage space on your Mac, not to mention the fact that they are known for storing your personal information.

So, here’s how to clear cookies on your Mac.

Two ways of clearing cookies on Mac

There are two ways to clear cookies on Mac — an easy one and a manual one. We’ll show you both. Let’s go!

How to clear cookies automatically

We’ll start with the easy way to get rid of browser cookies first. So, if you’re not into wasting efforts on cookie-brushing each time you need it, we recommend CleanMyMac X. It’s an amazingly useful app, specifically when it comes to dealing with browser junk. It clears browser cookies, caches, and histories, plus removes system junk from the Mac itself.

To clear cookies with CleanMyMac X:

  1. Download the app (a free trial is available).
  2. Go to the Privacy module and choose your browser. 
  3. Select the cookie icon and click Remove. 


The Privacy module erases all traces of your online activity from multiple browsers. Moreover, it allows you to conveniently manage all your application permissions and control access to the camera and microphone.

How to delete cookies manually

To be on the safe side, you should repeat these steps in your browser once in a while. It’s also a rule of thumb to clean up your caches and other stored info. A browser stuffed with old information may malfunction, show you something irrelevant, or get clingy with the advertisement.

Doing it on your own each time is a mess, so CleanMyMac X is a good deal. It reduces the whole ordeal to a few clicks, is pretty fast, and does a ton more useful things for Mac cleaning. It’s free to download, so give it a go.
