To allow third-party cookies on a Mac, the steps depend on the browser you are using. Here’s how to enable them in the most common browsers:

Safari

1. Open Safari on your Mac.
2. Click on Safari in the top menu bar and select Settings (or Preferences).
3. Go to the Privacy tab.
4. Deselect Prevent cross-site tracking to allow third-party cookies.
5. Deselect Block all cookies to ensure cookies are not blocked entirely.
6. Alternatively, you can go to Safari > Settings > Advanced and make sure Block all cookies is unchecked.
7. Close the settings; third-party cookies will now be allowed.

Safari blocks third-party cookies by default as part of its privacy features, so these settings must be turned off to allow them

Google Chrome

1. Open Chrome on your Mac.
2. Click the three dots menu at the top-right corner and select Settings.
3. Go to Privacy & Security.
4. Click on Cookies and other site data.
5. Select Allow all cookies or specifically Allow third-party cookies.
6. You can also choose to block third-party cookies only in Incognito mode if desired.
7. Close the settings tab.

This will enable third-party cookies in Chrome on your Mac

Firefox

1. Open Firefox on your Mac.
2. Click the menu button (three horizontal lines) and select Settings.
3. Go to Privacy & Security.
4. Under Enhanced Tracking Protection , select Custom.
5. Uncheck the box for Cookies to allow all cookies, or adjust to allow third-party cookies from sites you have visited.
6. Close the settings tab.

Firefox also blocks many third-party cookies by default but allows customization in privacy settings

. By following these steps in your preferred browser on Mac, you can enable third-party cookies to ensure full website functionality or targeted advertising if you choose. Remember that enabling third-party cookies can reduce privacy protections. If you only need them temporarily, consider disabling them again afterward.
