When you browse the internet, invisible scripts called trackers secretly monitor your activity, building a profile of your habits to serve targeted advertisements. If you use macOS, you do not need third-party extensions to combat this surveillance. Apple has built Intelligent Tracking Prevention directly into the Safari browser. To understand exactly who is trying to track you and verify that Safari is blocking them, you can use the built-in Privacy Report feature.
How Safari Intelligent Tracking Prevention Works
Unlike basic ad blockers that rely on static lists, Safari uses on-device machine learning to identify trackers based on their behaviour. It specifically targets “cross-site trackers”—data brokers that embed invisible pixels across thousands of different websites to follow you around the internet. Safari actively blocks these trackers from accessing your local data, and the Privacy Report provides complete transparency into this automated defence system.
What You Need Before Starting
The Privacy Report is a core feature of modern Safari. Ensure your Mac is running macOS Big Sur or newer, as this is when the feature was prominently introduced and refined. You must also ensure that the tracking prevention feature is actually enabled in your preferences.
Enabling Cross-Site Tracking Prevention
Before you can view a Privacy Report, you must confirm that Safari is actively blocking threats.
- Open the Safari browser on your Mac.
- Click on Safari in the top menu bar and select Settings (or Preferences on older macOS versions).
- Click on the Privacy tab at the top of the window.
- Ensure the box next to Prevent cross-site tracking is checked.
- You can now close the settings window.
Viewing the Privacy Report for a Specific Website
If you suspect a specific website is heavily monitoring your activity, you can instantly view a report for that exact page.
- Navigate to any website in Safari.
- Look at the address bar at the top of the window. To the left of the website URL, you will see a small shield icon.
- Click the Shield icon.
A dropdown menu will appear detailing exactly how many trackers were blocked on this specific page. This quick view is highly useful for identifying which news sites or online stores employ the most aggressive surveillance tactics.
Analysing Your Complete Privacy Report
To see a broader overview of your digital privacy, you can access the full report, which aggregates data across all your browsing sessions over the last 30 days.
- Open Safari.
- Click on Privacy Report from your Safari Start Page. If it is not visible on your Start Page, click Safari in the top menu bar and select Privacy Report.
The full report provides a comprehensive dashboard containing two critical views. The Websites tab lists the sites you have visited, ranked by how many trackers they attempted to deploy. The Trackers tab exposes the actual data brokers (such as doubleclick.net or google-analytics.com) attempting to monitor you, revealing which companies have the largest reach across the internet.
Recommendations for Total Privacy
The Safari Privacy Report confirms that your browser is successfully blocking cross-site tracking, but it does not make you entirely anonymous. Websites can still see your IP address. To achieve total privacy on a Mac, consider enabling Apple’s iCloud Private Relay (if you have an iCloud+ subscription), which masks your IP address from both the websites you visit and your internet service provider, working in tandem with Safari’s tracking prevention for maximum security.
