How to block Facebook on your Mac
To block Facebook on a Mac or MacBook, add facebook.com to Screen Time's restricted websites for a permanent Safari block, set a daily limit if you still want some access, or use a scheduled blocker such as Cactus for Mac to block it during recurring hours in every browser. Whichever method you choose, test www.facebook.com and m.facebook.com afterwards.
- Block Facebook all the time in Safari: add it to Screen Time's restricted websites.
- Allow a fixed amount each day: set a daily website limit in Screen Time.
- Block Facebook during work or study hours: create a recurring schedule in Cactus.
This guide covers Facebook in a web browser on your Mac, which is where most people use it on a computer.
Which Facebook domains to block
Facebook answers on several hostnames. As of October 2026, opening each one in a desktop browser gives this result:
facebook.comredirects towww.facebook.com, where the site actually loads.m.facebook.comandweb.facebook.comredirect towww.facebook.comon a desktop browser.fb.comandwww.fb.comredirect towww.facebook.com.messenger.comis Meta's old standalone chat site. Meta said that from April 2026 it would send desktop users tofacebook.com/messagesinstead.
In practice, facebook.com plus www.facebook.com is the block that matters, because every other route ends there. Add m.facebook.com and web.facebook.com as well if you want a block that doesn't rely on Facebook's redirects staying the same. Adding messenger.com is optional and harmless.
You don't need to block Meta's image and video delivery servers. Blocking those by hand tends to break other sites and doesn't make the Facebook block any stronger.
Method 1: Block Facebook with Screen Time
Screen Time is the free, built-in option. It keeps Facebook restricted until you change the setting, and Apple documents it as a Safari control.
- Open System Settings and choose Screen Time. Turn on Screen Time or App & Website Activity if macOS asks.
- Choose Content & Privacy and turn it on.
- Choose App Store, Media, Web, & Games.
- Under Safari, choose Limit Adult Websites, then Customize.
- Add
facebook.comunder Restricted. Addm.facebook.comtoo if you want to be thorough. - Open Facebook in Safari and confirm it no longer loads.
Apple describes these options in its guide to App Store, Media, Web, & Games settings. These steps match macOS 15 Sequoia and 26 Tahoe. On macOS 14 Sonoma, that pane is called Store, Web, Siri & Game Center Content, and the menu is Web Content instead of Safari. On macOS 27, some of Apple's help pages label the button Content & Privacy Restrictions.
Screen Time works best when someone else knows the Screen Time passcode. If you set the passcode yourself, removing Facebook from the list takes a few seconds, which is often all the impulse needs. For more on why Safari restrictions sometimes fail, see why Screen Time isn't blocking websites.
Method 2: Set a daily Facebook limit
A daily limit suits you if you check Facebook for groups, events, or Marketplace and don't want it gone entirely. It caps the total time; it doesn't block specific hours.
On macOS 14 to 26:
- Open System Settings, choose Screen Time, then App Limits, and turn it on.
- Choose Add Limit.
- Expand Websites at the bottom of the list, select
facebook.comif it's there, or add the URL. - Set the time for every day, or choose Custom to vary it by day.
- Select Block at end of limit so the limit actually stops access, then choose Done.
Apple's App Limits guide for macOS Tahoe has the current wording.
On macOS 27, Apple replaced App Limits with Time Allowances and Screen Time Schedules. Time Allowances work on categories such as Social Media, and schedules split the day into named time windows. Apple's macOS 27 guide describes these in terms of apps and notes that the newest features need version 27 on all your Apple devices. Check that Facebook in your browser is counted before relying on it.
Method 3: Block Facebook on a recurring schedule
A schedule fits when the rule is about time of day, for example "no Facebook on weekdays from 9:00 to 17:00", and you want Facebook back in the evening without touching any settings.
Cactus is a Mac website blocker built around one recurring schedule. To block Facebook with it:
- Open Cactus and choose the days the block should run.
- Drag the timeline to set the start and end time.
- Add
facebook.com. Cactus blocksfacebook.comandwww.facebook.comfrom that one entry. - Add
m.facebook.comandweb.facebook.comas separate entries if you want them blocked by name. - Turn the schedule on, then test Facebook in each browser you use.
Cactus blocks at the Mac level through the hosts file and the macOS packet filter, so the same block applies in Safari, Chrome, Firefox, Arc, and Brave without an extension. Once a block starts, Cactus has no button to end it early, and edits made during a block apply from the next one. The menu bar shows when access returns while the app is open. How Cactus blocks websites explains the details, including how a Mac administrator can still remove it.
Know its limits before you buy. Cactus has one schedule, so Facebook shares the same hours as every other site on your list. It can't block apps, and it doesn't run on iPhone or Windows. Browser settings like Chrome's Secure DNS, iCloud Private Relay in Safari, proxies, and some VPNs can affect blocking, so test with the setup you normally use. It costs $19.99 once, with a 7-day free trial that starts when you turn on your first schedule.
Other ways to block Facebook
You can also add Facebook to your Mac's hosts file by hand. It's free and works across browsers, but it has no schedule and you have to undo it yourself. See how to block websites with the hosts file. A browser extension is another option, but it only covers the browser it's installed in, and you can turn it off in a couple of clicks.
Which method should you use?
| Method | Best for | Browsers | Access returns |
|---|---|---|---|
| Screen Time restriction | Facebook off in Safari for good | Documented for Safari | When you change the setting |
| Daily limit | Some Facebook, but capped | Test each browser | Next day |
| Cactus schedule | No Facebook during set hours | All browsers on the Mac | At the scheduled end time |
Pick Screen Time if you rarely need Facebook and use only Safari. Pick a daily limit if a few minutes a day is fine and the problem is open-ended sessions. Pick a schedule if the trouble is specific hours, such as workdays, and you switch between browsers.
If Facebook is one of several sites pulling you away, the guide to blocking social media on Mac lists the domains for each network in one place.
What blocking Facebook does to Messenger and notifications
Messenger on the web
Blocking works on whole sites. Neither Screen Time nor Cactus can block the Facebook feed while leaving facebook.com/messages open. Since messenger.com now sends desktop users to Facebook, blocking Facebook on your Mac blocks web messaging too. If you need to reply to messages during blocked hours, use the Messenger app on your phone, or leave Facebook off your list.
Meta has also said the Messenger desktop app is no longer available, so there's no separate Mac app to block.
Facebook notifications
If you allowed Facebook to send browser notifications, they can still show up while the site is blocked, because they arrive through the browser's push service rather than from facebook.com. To stop them on macOS, open System Settings, choose Notifications, select Facebook under Application Notifications, and turn off Allow Notifications. Apple covers this in its Safari notifications guide. In Chrome or Firefox, remove the permission in that browser's site settings.
Common Facebook blocking problems
Facebook still loads in Chrome
Screen Time's website list is documented for Safari. If you use Chrome, Firefox, or Arc, test each one. Chrome's Secure DNS can also skip the Mac's hosts file, which affects hosts-based blockers, so check that setting in Chrome's privacy settings if a block works in Safari but not in Chrome.
The block works, then stops after a while
Check whether you turned on iCloud Private Relay, a VPN, or a proxy since you set up the block. Each one changes how your Mac reaches websites, so test again after any network change.
You keep removing the block yourself
Then the method has too little friction. Give the Screen Time passcode to someone else, or use a schedule that can't be ended early once it starts.
Test the result
Open facebook.com, www.facebook.com, m.facebook.com, and a shared Facebook link from a chat or email. Repeat in every browser you use. If you set a schedule, check once more after the block starts and again after it ends, so you know the Mac actually follows the rule you wrote.
