Free porn blocker for Mac: how to block porn on a Mac (2026)
You can block porn on a Mac for free by stacking two layers: Escape's free Safari blocker, which covers the same 40,000+ adult sites it blocks on iPhone, and macOS Screen Time, which is built in and resists Safari's reload-without-blockers option. Use a Screen Time passcode someone else holds. Each Mac browser brings its own engine, so keep your browsing in Safari, and delete the browsers you do not need or put a short Screen Time limit on them. The custom sites you block on your iPhone sync to your Mac over iCloud, with no account.
Free option 1. Escape's Safari blocker on your Mac
Escape blocks adult sites in Safari on your Mac for free, the same 40,000+ site list it uses on your phone, plus any sites you add. The custom sites you block on your iPhone sync to your Mac over iCloud, so you set them once instead of rebuilding the list. There is no account, so the list of what you block stays between your devices and never reaches a server we own. There is no second purchase to get the free Safari blocker on the Mac. It lives in your menu bar and launches at login. On the Mac, Escape's blocker works in Safari. Deep Block, which carries the block into every browser, is part of the premium tier on iPhone and iPad, and one subscription covers your iPhone, iPad, and Mac. More on Escape for Mac.

Free option 2. macOS Screen Time
Built into every Mac, no download, no cost. Open System Settings, then Screen Time, then Content & Privacy, then App Store, Media, Web, & Games, and limit adult websites. It covers Safari well and, unlike a plain content blocker, resists Safari's reload-without-blockers option, which is what makes it the bypass-resistant layer. Escape gives you one-tap guidance to turn it on. Set a Screen Time passcode that you do not hold yourself, the same idea as on a phone, so it is not a quick decision to turn off. The full walkthrough is in the bypass-resistance guide.
Free option 3. Keep your browsing in Safari
Escape's Safari blocker and Screen Time both center on Safari, and on a Mac, Escape's blocker works in Safari only. If you also have Chrome, Firefox, or another browser, the free fix is to keep your browsing in Safari. Make Safari your default browser and delete the browsers you do not need. If you need one for work, open System Settings, then Screen Time, and put a short daily limit on it. Then turn on Lock Screen Time Settings with a passcode someone else holds, so the limit is not a quick decision to undo.
What to skip
Be careful with "free" Mac blockers that are actually a short trial of a paid app, and with browser extensions that any user can remove in two clicks. An extension you can delete yourself is not really a block. The App Store or the app's own page shows the real pricing, so read it before you trust a "free" label.
The honest part about a Mac
A Mac is a more open machine than a phone, so any single free layer has more ways around it. That is a reason to stack a couple, not a reason to skip it. Escape's free Safari blocker plus Screen Time plus a passcode you do not hold covers most of it for nothing. The goal is to make it inconvenient enough in the weak moment that the urge passes.

Common questions
Is there a free porn blocker for Mac?
Yes. Escape blocks adult sites in Safari on your Mac for free, the same 40,000+ site list as on iPhone. macOS Screen Time is also built in and free. On a Mac, Escape's blocker works in Safari, so keep your browsing there and use Screen Time to limit any other browser.
Does macOS Screen Time block porn for free?
Yes. It is built into every Mac at no cost. In Screen Time, turn on Content & Privacy and limit adult websites. It covers Safari well, and you should set a passcode you do not hold yourself.
Do my blocks sync from my iPhone to my Mac?
With Escape, yes. The sites you block sync across your devices through iCloud, so you set them once instead of rebuilding the list on the Mac.
Are free Mac browser extensions enough to block porn?
Not really. An extension any user can remove in two clicks is not a real block. Screen Time is harder to undo, especially with a passcode held by someone else.
How do I block porn on a Mac?
A couple of layers work well together. Escape blocks adult sites in Safari on your Mac or MacBook for free, and it guides you to macOS Screen Time, which resists Safari's reload-without-blockers option. Set a Screen Time passcode someone else holds. Your custom blocks sync from your iPhone over your own iCloud, so you set them once, and they move between your devices without ever reaching a server of ours.
Does Mac Screen Time block porn in Chrome?
It covers Safari well, but third-party Mac browsers handle Screen Time unevenly because each one brings its own engine. The simpler fix is to keep your browsing in Safari with Escape's free blocker, and either delete Chrome or use Screen Time to put a limit on it.
