Cookies make the internet a smoother place. They help websites remember your login, preferences, and even the items in your shopping cart. But sometimes, third-party cookies are blocked on your Mac, causing websites to break or forget who you are.
If you need to enable third-party cookies, don’t worry! It’s easy to do, and we’ll guide you through the process step by step.
What Are Third-Party Cookies?
Before we get started, let’s quickly explain what third-party cookies are.
Cookies are small files stored by your browser to keep track of your website visits. There are two types:
- First-party cookies – Created by the website you are visiting.
- Third-party cookies – Created by other sites, like ads or embedded content.
Some websites rely on third-party cookies to function properly. If they are blocked, you might have trouble logging in, streaming content, or using certain web features.
How to Allow Third-Party Cookies on Mac
The process depends on the browser you are using. Below, we’ll cover the most popular ones.
Safari
Since macOS Big Sur, Safari disables third-party cookies by default. But you can change this:
- Open Safari.
- Click on Safari in the top menu.
- Select Settings (or Preferences on older versions).
- Go to the Privacy tab.
- Uncheck “Prevent cross-site tracking.”
That’s it! Third-party cookies are now enabled in Safari.

Google Chrome
Chrome also blocks some cookies by default, but here’s how to enable them:
- Open Chrome.
- Click the three dots in the top-right corner.
- Select Settings.
- Go to Privacy and security.
- Click Cookies and other site data.
- Select “Allow all cookies” or adjust settings as needed.
Now, Chrome will allow third-party cookies on your Mac.

Firefox is privacy-focused but lets you change cookie settings:
- Open Firefox.
- Click the three lines in the top-right corner.
- Select Settings.

- Uncheck “Cookies” or set it to allow third-party cookies.
Firefox will now allow cookies based on your settings.

When Should You Allow Third-Party Cookies?
Allowing all cookies isn’t always recommended. Some are used for tracking your activity across different websites.
So, when should you enable them?
- When a website isn’t working properly.
- For online banking or services that require third-party cookies.
- When using trusted sites you visit frequently.
