Block Adult Websites on a Mac: Screen Time and DNS

You can add adult-website restrictions to a Mac using a filtering DNS service and the Screen Time controls available for your macOS version. Start with the browser you use every day, then verify what the selected restriction actually covers.

For a Muslim trying to stop watching porn, this is a practical part of changing the environment around the habit. You can work through the general quitting guide alongside the Mac setup.

Check your Mac before following a menu path

Open Apple menu → About This Mac and note the macOS version. Also note whether you use Safari, another browser, or both, and whether the computer belongs to you or is managed by work or school.

Apple’s Screen Time menus vary by system version. The Safari procedure below is specifically documented for macOS Tahoe 26. Use Apple’s version selector if your Mac differs. Do not assume an iPhone tutorial maps directly to the Mac.

If you share the computer, explain the intended restrictions to the other people who use it. Keep any request for accountability separate from password sharing or reading someone’s history.

Add a filtering DNS service to your network connection

Cloudflare documents an adult-content filtering profile that you can configure for a Mac’s network service. Record the existing DNS settings first, particularly if your computer already has a custom network configuration.

Following Cloudflare’s macOS setup guide:

1. Open System Settings → Network.
2. Select the network service you use, such as Wi-Fi or Ethernet, then Details → DNS.
3. Configure the adult-content profile’s IPv4 resolvers: 1.1.1.3 and 1.0.0.3.
4. Configure its IPv6 resolvers: 2606:4700:4700::1113 and 2606:4700:4700::1003.
5. Confirm the changes with OK.

These are DNS server addresses, not addresses to assign to the Mac itself. If the connection is managed or the existing entries are unfamiliar, ask the network administrator for help with the filtering policy.

A DNS filter works with website domains. It is not a promise to classify every image, message, or video inside a service you still allow. How DNS filtering works.

Use Safari restrictions in macOS Tahoe 26

For this version, Apple’s guide places the control under System Settings → Screen Time → Content & Privacy → App Store, Media, Web & Games. Turn on Screen Time and content restrictions if prompted. In the Safari section, select Limit Adult Websites.

Apple describes this as limiting access to many adult websites. Customize lets you add specific allowed or restricted sites. Allowed Websites Only provides a stricter list-based option. These instructions and their Safari scope come from Apple’s macOS Tahoe 26 guide.

Choose the list-based option only after identifying the websites needed for ordinary tasks. Work sign-ins, school resources, and other essential services may involve more than the first address you type.

For another macOS version, follow the matching Apple guide rather than forcing these menu labels to fit. The DNS method above is a separate control; it does not depend on the Safari panel having the same name.

Make the boundary apply to your real browsing

Do not assume a restriction documented for Safari proves coverage in every other browser. Check each browser you actually use, under your usual Mac account.

Browsers can have their own encrypted-DNS configuration. Confirm that it matches your chosen filtering service; a provider name alone does not identify the adult-filtering profile. Cloudflare explains this distinction in its browser setup documentation.

If you use a managed connection or security software, ask its administrator or vendor how filtering is applied. Avoid stacking unfamiliar tools merely because each promises more protection.

Verify with harmless checks

First, open an ordinary reference or work page to confirm usable internet access. Then use your filtering provider’s official category test. Cloudflare links its test from the Families setup documentation.

For a manual restricted-sites list, a neutral website can test that specific rule. A successful manual block verifies that rule in the tested browser; it does not prove the adult-content category catches every site.

Keep the result brief: “Safari, home Wi-Fi, category test blocked, work site opened.” If you also use Ethernet or another browser, verify that ordinary setup separately. Repeat after a relevant system, browser, or filtering change.

If a legitimate service fails, review its exact requirement or ask the provider about a mistaken category. Keep the correction narrow enough to preserve the boundary you intended.

Give the Mac a place and a stopping point

Choose one routine that does not depend on menu settings: work at a desk, keep the laptop outside bed, or close it after a defined evening task. Prepare a book, a short household task, or a familiar worship routine for the time you would otherwise keep browsing.

If the same pattern also starts on your phone, Nafs can interrupt selected phone apps and connect screen time with ibadah. Keep that phone routine separate from the Mac’s website restrictions.

Finish by writing down which Mac account and browser you checked. That gives you a useful starting point if a future update changes the behavior.
