Have you ever noticed that if you frequently visit the same websites, they grow more personalized over time? It is because of cookies. Convenient as they are, they may also pose severe privacy risks, so it is safer to remove them. If you don’t know how to do it, you’ve landed in the right place. Here’s our 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.
There are several main types of cookies:
- Session cookies. Cookies that don’t collect any personal data and are stored as a temporary file. They help a website perform any necessary actions, such as logging in or adding items to a cart. Once you end your browsing session, they are deleted automatically.
- Stored cookies. Cookies responsible for storing your login credentials and any account settings. They allow you to stay logged in on the website even if you close the tab. These are functional cookies, and they exist on your hard drive until you remember to remove them.
- Third-party cookies. Cookies that collect personal preferences and other data to share it with third parties, like advertising companies. If you see ads relevant for you when you use your browser, it is because of these cookies.
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. There are two different ways to do it — manual and automatic with the help of a Mac cleaner app.

Why do you need to clear cookies?
To be on the safe side, you should repeat the steps we outlined above 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 or get clingy with the advertisement.
But there are other reasons why you would want to delete cookies:
- Removing cookies improves website performance because when you delete settings stored in cookies, everything starts to work as it should .
- If you are interested in seeing ads, they will be more relevant because websites will collect newer information about you.
- Clearing out cookies from time to time helps improve privacy not only because you delete personal data but also because you log out of websites.
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.
