To enable third-party cookies on a Mac, you must adjust the privacy settings within your specific web browser. While most browsers allow you to toggle this on for all sites, Apple's Safari uses which may still limit some cross-site tracking even when general cookies are enabled. Safari Open Safari and click on Safari in the top menu bar. Select Settings (or Preferences in older macOS versions). Navigate to the Advanced tab at the top right. Deselect (uncheck) the box for Block all cookies .
Note: Most modern browsers (like Safari and Chrome) have evolved to block third-party cookies by default for privacy reasons. While you can enable them in some browsers, others (like Safari) use "Intelligent Tracking Prevention," which cannot be fully disabled, though you can adjust settings to allow certain cross-site functionality.
