You can block websites on Mac using Screen Time, the Terminal hosts file, browser policies, DNS filtering, or device-management controls. For most individual users, Screen Time is the simplest option; businesses managing multiple Macs usually need centrally enforced web-filtering or browser policies.
Key Takeaways
- Screen Time: Best built-in option for blocking specific sites or limiting web content without installing additional software.
- Terminal: Editing the Mac hosts file can block domains across browsers, but it requires administrator access and manual maintenance.
- Browser controls: Extensions and managed browser policies provide more granular URL-level restrictions.
- Network filtering: DNS and proxy-based controls can restrict categories or domains before traffic reaches the browser.
- Managed Macs: Organizations can push web-content restrictions centrally through device management instead of configuring every Mac individually.
How Do You Block Websites on Mac?
The easiest way to block websites on a Mac is through Screen Time → Content & Privacy → App Store, Media, Web & Games, then configure web access and add unwanted URLs to the restricted list. Apple provides options for unrestricted browsing, limiting adult websites, and customizing allowed or restricted URLs.
The best method depends on where you want the block enforced.
| Method | Best For | Coverage | Admin Skill |
|---|---|---|---|
| Screen Time | Personal use, children | Built-in web restrictions | Low |
| Hosts file | A few static domains | System resolver | Medium |
| Browser controls | Browser-specific rules | Individual browser | Low–Medium |
| DNS/network filter | Category/domain filtering | Network/device | Medium |
| Device management | Business and school Macs | Centrally managed devices | High |
Method 1: How to Block Websites on Mac Using Screen Time
Screen Time is the quickest built-in method when you want to restrict individual websites without adding another application.
Apple’s current macOS workflow is:
- Open Apple menu > System Settings.
- Select Screen Time.
- Open Content & Privacy and enable restrictions.
- Select App Store, Media, Web & Games.
- Find Access to Web Content.
- Choose Limit Adult Websites.
- Click Customize.
- Under Restricted, click the + button.
- Enter the website URL.
- Click Done.
The exact labels can vary slightly between macOS releases, but Apple’s current Screen Time documentation follows this general structure.
For example, if example.com is distracting during work, adding it to the restricted list prevents access according to the configured Screen Time policy.
You can also use an allow-only approach when the user should access only a small set of approved websites. That can be more practical for shared Macs, kiosks, classroom scenarios, or tightly controlled workstations.
Method 2: How to Block Websites on Mac Using Terminal
Mac users comfortable with Terminal can block a domain by modifying the /etc/hosts file.
Open Terminal and run:
sudo nano /etc/hostsThen add entries such as:
127.0.0.1 example.com
127.0.0.1 www.example.comSave the file, exit the editor, and refresh macOS DNS resolution:
sudo dscacheutil -flushcache
sudo killall -HUP mDNSResponderThe hosts file maps hostnames locally. Pointing a domain to the loopback address prevents normal DNS resolution to the site’s actual server.
The catch? You need to account for different hostnames and subdomains. It also has no built-in scheduling, category filtering, centralized reporting, or administrative policy enforcement. Competitor guides commonly recommend it for a handful of static domains rather than large-scale filtering. (FocusDragon)
Method 3: Block Websites on Mac Using Browser Controls
Browser-level blocking is useful when access needs to be restricted only inside one browser.
A Safari user will generally rely on macOS Screen Time rather than a standalone Safari blocklist. Chrome and Firefox can use extensions, while administrators can enforce native browser policies.
For managed Chrome browsers, Google supports URLBlocklist and URLAllowlist policies. Admins can block individual domains, URL patterns, or nearly all websites while creating exceptions for approved resources. Google currently supports up to 1,000 URL entries in these policies.
This approach works well when the requirement is specifically:
“Users may use Chrome, but they must not access these domains.”
It is less appropriate if users can simply switch to an unmanaged browser.
Method 4: Block Websites Using DNS or Network Filtering
DNS filtering moves the control away from the browser. Instead of waiting for Safari or Chrome to decide whether a page should load, DNS policies can prevent selected domains from resolving in the first place.
This is useful when organizations need to block categories such as:
- gambling
- adult content
- malware
- social networks
- streaming services
- known phishing domains
Apple supports managed DNS settings, DNS proxies, network proxies, and other content-filtering methods on Apple devices.
Network-level controls can cover more traffic than a browser extension, but administrators should test VPNs, alternate DNS resolvers, applications, and off-network usage before assuming a policy is universal.
Method 5: How IT Admins Can Block Websites on Managed Macs using Scalefusion
When you need a reliable, scalable, and centrally managed solution, Scalefusion macOS device management steps in. It lets IT admins oversee browsing activities on managed Mac devices professionally, using Web Content Filtering settings.
Here’s a clear breakdown of how to set it up:
Step 1: Create a master list of allowed websites
Before applying restrictions, you’ll first need to define what websites users can access.
- Log in to your Scalefusion Dashboard.
- Navigate to Device Profiles & Policies → Allowed Websites.
- Click Allow A WEBSITE.
- Fill in:
- Website Name (How it’ll appear as a web clip if you choose to show it).
- Website Link (Complete URL; wildcards are not supported).
- Visible on Home Screen toggle (decide if you want a clickable shortcut on the Dock).
- Under Apple Settings, optionally upload a logo for your web clip.
- Click SAVE.
The site now appears in your master list.
Step 2: Enable content filtering on Mac devices
Now that you have your website list, apply it to devices:
- Go to Device Management → Device Profiles.
- Either Create New Profile or Edit an existing Mac Device Profile.
- Click on the Content Filtering option.
- Under Content Filtering:
- Disable Siri & Dictation (optional if you want extra restrictions).
- Hide Profanity in Dictionary & Dictation (optional).
- Configure Allowed Websites: Enable this to start website control.
- You will now have two options:
- Allow Access to Allowed Sites Only: Users can access only the websites from your master list.
- Limit Access to Adult Websites: Let Safari’s built-in filter work while manually allowing some extra sites.
- Add Web-Clips to Dock: Optional if you want visual shortcuts to approved websites.
- Select from your Allowed Websites list the websites you want active for this profile.
- Click SAVE.
That’s it. All Macs assigned to this Device Profile will now follow the browsing restrictions you’ve set.

Which Mac Website Blocking Method Should You Use?
For one personal Mac, start with Screen Time. It is already included with macOS and requires little configuration.
Use the hosts file when you need a simple technical block for a few domains. Browser policies make more sense when the restriction applies specifically to a managed browser.
For businesses, schools, or fleets of Macs, centrally managed content filtering is usually the more scalable model because administrators can apply and update policies without touching every device individually.
Why Is a Blocked Website Still Accessible?
If a website still loads after you block it, check where the restriction is being enforced.
Common causes include:
- only one browser is configured
- another subdomain is being used
- the user switched browser profiles
- the hosts file contains only the
wwwor non-wwwhostname - a VPN or proxy changes how traffic is resolved
- the policy hasn’t refreshed yet
- an unmanaged browser doesn’t receive the organization’s browser policy
For managed Chrome, Google recommends checking chrome://policy to verify that URLBlocklist and URLAllowlist policies have been successfully applied.
How to Unblock Websites on Mac
To remove a Screen Time block, return to the same web-content settings, select the restricted URL, and remove it.
For a hosts-file block, reopen:
sudo nano /etc/hostsDelete the relevant entries, save the file, and flush the DNS cache again.
Managed-device or browser restrictions must normally be changed by the administrator controlling the policy.

FAQs
1. How do I block a website in Safari on Mac?
Use System Settings > Screen Time > Content & Privacy, configure web-content restrictions, and add the website to the restricted list. Safari uses macOS web-content controls rather than providing a separate traditional website blacklist.
2. Can I block websites on Mac without installing software?
Yes. Screen Time is built into macOS, and advanced users can also block domains by editing the /etc/hosts file through Terminal.
3. Can I block websites on every browser on a Mac?
Yes, but choose a system- or network-level approach rather than relying solely on a browser extension. In managed environments, web-content filters, DNS policies, or device-management configurations provide broader control.
4. How do I permanently block a website on Mac?
No ordinary user-configurable method should be treated as literally permanent. Screen Time settings, hosts-file entries, extensions, and policies can all be changed by someone with sufficient permissions. For stronger enforcement, separate normal user privileges from administrative control and centrally manage restrictions.
5. Can IT admins remotely block websites on Macs?
Yes. Apple supports web-content filtering through device-management configurations, including denied URLs, allowed URLs, specific-sites-only access, proxies, DNS controls, and advanced filtering mechanisms.
