Quick answer: On iPhone, go to Settings → Screen Time → Content & Privacy Restrictions → App Store, Media, Web & Games → Web Content, then choose Limit Adult Websites. On Mac, open System Settings → Screen Time → Content & Privacy → App Store, Media, Web & Games and set Safari access to Limit Adult Websites.
If Safari is where the habit usually starts, the setup matters less in theory and more in practice: can you turn blocking on quickly, will it stay on, and does it cover both your iPhone and your Mac without turning into a project?
Apple already includes free website restrictions that can block adult websites in Safari. For some people that is enough. For others, a dedicated blocker is easier to keep enabled because it is built around one job instead of a broad parental controls menu.
Block porn sites in Safari on iPhone
- Open Settings.
- Tap Screen Time.
- Open Content & Privacy Restrictions and turn it on.
- Tap App Store, Media, Web & Games.
- Tap Web Content.
- Select Limit Adult Websites.
That applies Safari’s built-in adult website filter. If there are specific domains you already know are a problem, add them under Never Allow so you are not relying only on Apple’s general filter.
Menu names can change with iOS updates or a managed family account. Apple’s current iPhone and iPad parental-control guide documents the web-filter options and account-specific paths.

Block porn sites in Safari on Mac
- Open System Settings.
- Select Screen Time.
- Open Content & Privacy.
- Select App Store, Media, Web & Games.
- Under Safari, select Limit Adult Websites.
On Mac, this gives Safari the same basic adult website filter. As on iPhone, you can add specific websites manually when you want stricter coverage for the sites you actually try to reach. Apple’s current Mac Screen Time guide lists the same setting and customization options.
What Screen Time does and does not block
Limit Adult Websites is a free first layer. It filters many known adult domains and lets you add individual sites to a Never Allow list. It is not a guarantee that every explicit page, search result, social feed, or newly created domain will be blocked.
Screen Time is also broader than Safari. Its web-content restriction can apply to web access in other browsers on the device, although behavior can vary by app and Apple software version. Test the browsers and private-browsing routes you actually use rather than assuming the setting covers every path.
When built-in Safari blocking is enough
Apple’s settings are a good fit when you want a free starting point and you are willing to manage the setup manually. If your main goal is simply “block porn in Safari today,” Screen Time is the fastest default.
When a dedicated blocker is a better fit
Screen Time lives inside a larger settings area that was not designed specifically for an adult who has personally chosen to stop. That is where a focused app can be better: less hunting through menus, a simpler on-ramp, and a visible reminder of the progress you are protecting.
Nohub is built for that use case. It uses device-level blocking across all browsers, works on both iPhone and Mac, and keeps your timer and progress on your device. Compare it with Screen Time on the Safari porn blocker page, see the equivalent Chrome blocking steps, or start with the platform-specific iPhone page or the Mac page.
Make Safari blocking harder to bypass
- Use the same blocking setup on every Apple device you use regularly.
- Add the specific sites you already know you reach for.
- Remove backup browsers you only keep as a workaround.
- If it fits your situation, let someone else keep the Screen Time passcode.
- Choose the setup you are most likely to leave enabled for months, not days.
Fix common blocking gaps
A specific site still opens
Return to Web Content, keep Limit Adult Websites selected, and add that domain under Never Allow. Add alternate domains you know the site uses as well.
The setting is easy to switch off
Set a Screen Time passcode that is different from your device passcode. If it is appropriate for your situation, ask someone you trust to keep it. Apple’s filter is only useful while the restriction remains enabled.
Another browser creates a gap
Test that browser after enabling the restriction. Remove browsers you keep only as a workaround, or use a device-level blocker if you want one focused setup across browsers.
Best next step
If you want the quickest free setup, turn on Apple’s Safari restrictions first. If you want something more purpose-built for adults who chose to stop, compare the built-in route with a blocker designed around that single job.
