To stop cross-site tracking in Safari on Mac, open Safari > Settings, click Privacy, and select Prevent cross-site tracking. Once it is on, Safari deletes tracking data from third-party providers you don't visit directly, and it limits fingerprinting.

## Quick answer

- Open Safari > Settings (⌘,), click Privacy, and select the check box for Prevent cross-site tracking.
- The setting deletes tracking data from third-party providers unless you visit them directly and interact with them.
- It also blocks tracking from embedded Share, Like, and Comment buttons, and it limits fingerprinting.
- It does not stop the site you are on from tracking your activity there, so review the other Privacy options too.
- If a site breaks, reload with ⌘R, test in a Private window, then remove only that site's data.

Applies to: Safari on Mac, including Safari 27 on macOS Sequoia and Tahoe. Time: 2 min. Difficulty: Easy.

## What you need

- A Mac with Safari installed and open.
- The sign-in details for any site you use often, in case a site asks for them again.
- About two minutes, plus a few minutes if a site needs fixing.

## How to Stop cross-site tracking in Safari on Mac in Safari on a Mac

1. **Open Safari.** Open Safari and make it the front app. Click its icon in the Dock, or open it from Spotlight. Check that the Safari menu appears in the menu bar at the top of your screen.
2. **Open Safari Settings.** (Safari > Settings) Shortcut: ⌘,. Choose Safari > Settings from the menu bar. You can also press Command and comma (⌘,) while Safari is the front app. The Settings window opens. Tip: If the item name differs on your Mac, check Apple's guide for your macOS version.
3. **Open the Privacy pane.** (Settings > Privacy) Click Privacy in the Settings window. The pane holds Prevent cross-site tracking, Hide IP address from trackers, Manage Website Data, and Advanced Settings. Tip: Keep the Settings window open. You will come back to it for the advanced option.
4. **Select Prevent cross-site tracking.** (Settings > Privacy > Prevent cross-site tracking) Select the check box next to Prevent cross-site tracking. Safari then deletes third-party tracking data on a periodic basis. It also blocks tracking from embedded Share, Like, and Comment buttons. Tip: Apple's guide shows no shortcut and no confirmation dialog for this step. Look at the check box to confirm it is selected.
5. **Review stored website data.** (Settings > Privacy > Manage Website Data) Click Manage Website Data to see stored data by site. Select a site you no longer use, click Remove, then click Done. Know your sign-in details first for any site that uses sign-in. Tip: Removing data for a site you use every day can sign you out. Have your password manager ready.
6. **Check the advanced fingerprinting option.** (Settings > Privacy > Advanced Settings) Click Advanced Settings and find Use advanced tracking and fingerprinting protection. Leave it selected unless a site you need will not load. Apple's pages do not say whether it is on by default, so read the check box on your Mac. Tip: Turning this option off is a fix for broken sites, not a privacy upgrade.
7. **Test a site you use.** Shortcut: ⌘R. Open a site that loads third-party content, such as a news site or a shop. Reload it with ⌘R. If the page loads normally, the setting is working with that site. Tip: If the page fails to load, go to the troubleshooting list on this page.
8. **Check Privacy Report.** (Safari > Privacy Report) Choose Safari > Privacy Report to see the cross-site trackers Safari prevented on the current site. Open it again after a week to see the weekly report. Tip: The report covers the site you are viewing, so check it on a few sites you use.

## Turn on Prevent cross-site tracking in Safari

This is the setting that does the main work. Apple calls it Prevent cross-site tracking, and it sits in the Privacy pane of Safari Settings. You turn it on once. It keeps running after that, so you don't need to revisit it unless you want to change a related option.

The whole job takes about two minutes. Start with Safari as the front app. Then open Settings with Safari > Settings, or press Command and comma (⌘,). Apple's keyboard shortcut list confirms that ⌘, opens settings for the front app.

## What the setting does, in plain terms

Many websites load content from other companies. A video player, an ad, a comment box, or a like button can come from a third party. That third party can set cookies and store other data in your browser. Across many sites, that data can show the same company where you go.

With the setting on, Safari deletes a third-party content provider's cookies and website data. The exception is a provider you visit and interact with as a first-party website. Apple says Safari does this periodically, so the cleanup runs on a schedule, not the moment you select the box.

Safari also handles tracking from embedded buttons. Here is what Apple's guide lists:

- Deletes cookies and website data from third-party providers you don't visit directly.
- Blocks tracking from embedded Share, Like, and Comment buttons, even if you never click them.
- Asks for your permission before an embedded button can see your activity on other websites.
- Limits fingerprinting by presenting a simplified version of your Mac's system configuration.

The button rule can be surprising. A Like button on a news page can load before you touch it. If you want the button to work, Safari asks first. Apple's guide describes that prompt in general terms, without the exact wording, so expect a permission question rather than a fixed message.

Fingerprinting works differently from cookies. A site reads many small details about your browser and system, then combines them into an identifier. Safari reduces this by showing a simplified system profile, so your Mac looks more like other Macs. A separate advanced option also covers fingerprinting, and it is covered below.

## What the setting does not stop

Prevent cross-site tracking targets third parties. It does not stop the site you are on from knowing what you do there. If you log in to a shop, that shop still ties your visits and purchases to your account.

Apple's Safari page says Safari already blocks third-party cookies by default. It also says Safari uses on-device intelligence to help prevent cross-site tracking. Those protections run alongside this setting. The Prevent setting adds a cleanup step that removes tracking data already stored on your Mac.

> **Logged-in activity:** A site you sign in to can still link your visits to your account. The setting only targets third-party providers, so turning it on does not make a logged-in account anonymous.

- **60%** Share of cookies on the top one million websites that are third-party, July 2025 crawl (desktop 59%, mobile 60%) ([source](https://almanac.httparchive.org/en/2025/cookies))
- **7.83%** Safari share of worldwide desktop browser use in October 2026, covering all desktop systems, not Mac alone ([source](https://gs.statcounter.com/browser-market-share/desktop/worldwide))

The numbers show why third-party cookies matter. HTTP Archive's July 2025 crawl found that about 60% of cookies on the top one million websites were third-party. On desktop, 59% of those cookies were third-party. On mobile, the figure was 60%. That figure counts cookies, not websites.

StatCounter puts Safari at 7.83% of worldwide desktop browser use in October 2026. Chrome sat at 66.98% for the same month. StatCounter's count covers all desktop systems, so treat it as market context, not a Mac number.

## Other privacy options in the same pane

The Privacy pane has four more options beside Prevent cross-site tracking. Apple's guide lists Hide IP address from trackers, Manage Website Data, Require Touch ID to view locked tabs, and Advanced Settings. Each one covers a different gap, so decide which gap you care about first.

| Option | What it does | Trade-off |
| --- | --- | --- |
| Hide IP address | Stops known trackers from using your IP address. The stronger choice also hides it from websites. | The stronger choice requires iCloud Private Relay, which needs an iCloud+ subscription. |
| Manage Website Data | Lists stored website data by site, so you can remove one site at a time. | Removing a site's data can sign you out, so know your sign-in details first. |
| Advanced Settings | Holds the option Use advanced tracking and fingerprinting protection. | Turning that option off can fix a broken site, but it lowers the protection. |

_Options in Settings > Privacy that sit beside Prevent cross-site tracking._

The table shows the gaps. The IP option matters if a tracker can see your address. Manage Website Data matters if you want stored data gone now, not at the next cleanup. The advanced option matters most when a site breaks.

The advanced option needs a closer look. Apple's troubleshooting page says a site may ask you to deselect Use advanced tracking and fingerprinting protection in Advanced settings. Apple's pages do not settle whether that option is on by default, so check the check box on your own Mac instead of guessing.

## Check what Safari blocked on a site

Once the setting is on, you can see its work. Choose Safari > Privacy Report. It lists the cross-site trackers Safari has prevented from profiling you on the current site. A weekly report shows how protection looks over time.

Try it on a page you visit often, such as a news site or a shop. Open the report there, then open it again after a week. You will see what changed, and you will know whether the setting is doing anything for the sites you use.

## Fix a site that breaks after you change the setting

Some sites rely on third-party cookies to load a sign-in, a cart, or a player. When one breaks, change one thing at a time. Start with the least drastic fix and work down the list.

1. Reload the page with ⌘R and try again.
2. Open a Private window with ⇧⌘N and load the site there. If it works, cookies or cached data are the likely cause.
3. Go to Settings > Privacy > Manage Website Data, select the site, click Remove, then click Done.
4. Deselect Use advanced tracking and fingerprinting protection under Advanced settings, or allow cookies for that site.
5. Check any VPN, proxy, DNS, or security software. Test the page on another device on the same network.

Per-site changes live in Websites settings. Apple notes that Privacy and Security settings apply to all sites, while Websites settings are per-site. Change the one site that breaks and leave the rest of your protection in place.

## Mistakes people make with this setting

- Assuming the setting blocks all tracking. It targets third-party providers, so the sites you visit still see your activity.
- Clearing all website data to fix one site. Remove only that site in Manage Website Data.
- Removing data without your sign-in details. Apple advises knowing them first if a site uses sign-in.
- Using a Private window as proof of protection. It is a test for broken pages, not a tracking audit.
- Turning the setting off to fix one site. Change that site's settings instead, and keep the protection on everywhere else.

## Safari and macOS versions

Apple's Safari 27 security page says Safari 27 was released on September 14, 2026, for macOS Sequoia and macOS Tahoe. Apple's privacy guide also lists macOS 27 Golden Gate in its version selector. The guide does not say whether the steps change by version, so this page follows Apple's wording.

If your menus look different, open the version selector on Apple's Safari privacy guide and pick your macOS. Compare the steps there before you change anything. The option you want is named Prevent cross-site tracking in every version Apple lists.

## What to do next

Turn the setting on, then check Privacy Report once a month. Clear data for sites you no longer use, and keep the advanced option on unless a site you need breaks.

## Shortcuts

- Open Safari Settings: ⌘,
- Reload the page: ⌘R
- Open a Private window: ⇧⌘N
- Force quit Safari: ⌥⌘Esc

## If it does not work

- **A site breaks after I turn on the setting** Reload with ⌘R. Open a Private window with ⇧⌘N to see whether cookies or cached data cause it. Then remove that site's data in Manage Website Data, and deselect Use advanced tracking and fingerprinting protection if needed.
- **A Like or Share button is missing or asks for permission** This is the setting working. Safari blocks embedded buttons and asks before a site can see your activity on other websites. Allow it only if you need that button, and expect a permission prompt rather than an exact message.
- **A page still fails after the privacy changes** Apple notes that Privacy and Security settings apply to all sites, while Websites settings are per-site. Check the Websites settings for that one site, and allow cookies there if the site needs them.
- **Pages won't load on any site** Check custom proxy or DNS settings, and any VPN or security software that changes network connections. Open the page in another browser or on another device on the same network to test.
- **The Report a Website Issue item is missing** Apple says this item appears only after you reload the page in Safari 26 or later. Reload with ⌘R, then open the Page Menu and look again.
- **Safari freezes while you test** Force quit Safari with ⌥⌘Esc, reopen it, and reload the page. If the freeze returns, test the page in a Private window with ⇧⌘N.

## FAQ

### Where is Prevent cross-site tracking in Safari on Mac?

Open Safari > Settings, or press Command and comma (⌘,). Click Privacy, then select the check box for Prevent cross-site tracking. Apple's guide uses this same path.

### Does Prevent cross-site tracking block all trackers?

No. It targets third-party content providers and embedded buttons. The sites you visit directly can still track your activity on their own pages, and logins still tie your activity to your account.

### Will turning this setting on break websites?

Some can. Sites that rely on third-party cookies for sign-ins, carts, or players may fail to load. Test with a Private window, remove that site's data if needed, and deselect the advanced option only for that site.

### What happens to my logins if I remove website data?

You may need to sign in again. Apple advises knowing your sign-in details before you remove data for a site that uses sign-in.

### Does the setting change in Safari 27?

Apple's Safari 27 security page says it was released September 14, 2026, for macOS Sequoia and Tahoe. Apple's guide does not say whether steps differ by version, so check its version selector if your menus look different.

### Does Hide IP address stop every website from seeing my IP address?

Only the stronger option does. The other choice hides your address from trackers. The stronger choice requires iCloud Private Relay, which needs an iCloud+ subscription.

### Can I see what Safari blocked on a site?

Yes. Choose Safari > Privacy Report. It lists the cross-site trackers Safari prevented on the current site, and a weekly report shows protection over time.
