How to Block a Website on Mac: Your Complete Guide
If you’re looking to block a website on your Mac—whether for productivity, parental controls, or simply to avoid distractions—you’re in the right place. Macs offer several effective ways to block unwanted websites, from built-in parental controls to third-party apps, browser extensions, and manual system edits. This guide will take you step-by-step through each method, explain their pros and cons, and help you choose the best solution for your needs.
Why Block Websites on Your Mac?
Blocking websites can help you:
- Stay focused and productive by minimizing distractions.
- Protect children from inappropriate content.
- Prevent the use of specific sites at home or work.
- Avoid malware, scam, or phishing websites.
Different situations call for different blocking methods. Let’s explore your options from simple to advanced, covering every user level.
1. Use Screen Time (Built-in Parental Controls)
Screen Time comes with macOS and is a robust tool for limiting website access. It’s perfect for those who want an easy-to-use, system-level solution—great for family computers.
Step-by-Step: Blocking Websites with Screen Time
- Go to the Apple menu () and select System Settings (or System Preferences on older macOS versions).
- Click on Screen Time.
- Choose your user account (or your child’s, if you’ve set up Family Sharing).
- Go to the Content & Privacy Restrictions section.
- Click Turn On to enable restrictions, then select Content.
- Under Web Content, choose Limit Adult Websites or Allowed Websites Only.
- To block specific sites, click Customize next to Limit Adult Websites. Press the “+” button under Never Allow and enter the website address.
Benefits
- Easy setup, no downloads needed.
- Granular control over allowed/disallowed sites.
- Works system-wide (all browsers).
Challenges
- Password-protect your Screen Time settings, or savvy users may change them.
- Advanced users may circumvent with VPNs or alternate accounts.
2. Edit Your Mac’s Hosts File (Manual Method)
The hosts file maps website addresses to local addresses. By redirecting a website to your own computer’s address (localhost), you can stop it from loading.
Step-by-Step: Blocking Websites Using the Hosts File
- Open Terminal (find it in Applications > Utilities).
- Type:
sudo nano /etc/hosts
Press enter and provide your Mac’s admin password. - Use the arrow keys to navigate to the bottom of the file.
- On a new line, type:
127.0.0.1 website-you-want-to-block.com
For example:
127.0.0.1 facebook.com - Add additional sites on new lines as needed.
- Press Control + O to save, then Control + X to exit.
- To apply changes, type:
sudo dscacheutil -flushcache
Press enter.
Benefits
- Free and doesn’t require extra software.
- Blocks websites across all browsers and apps.
Challenges
- Editing system files is risky for beginners—mistakes can cause issues.
- Requires admin privileges.
- Easy for advanced users to reverse.
3. Use Third-Party Website Blocker Apps
Sometimes, built-in methods aren’t enough. Dedicated website-blocking apps can offer scheduling, password protection, and more robust features.
Popular Apps to Consider
- Focus: Lets you block distracting sites and apps, set timed sessions, and customize the blocklist.
- Freedom: Blocks sites and apps across multiple devices. Ideal for those needing focus on several platforms.
- Cisdem AppCrypt: Besides blocking websites, it can also block specific applications.
- Cold Turkey: Well-known for its strict approach; once a block session starts, it can’t be stopped until the timer ends.
How to Use a Typical Blocker App
- Download and install your chosen app.
- Open the app and enter/adjust your blocklist.
- Set a schedule or start a blocking session.
- Some apps offer password protection or more advanced features—customize as needed.
Benefits
- User-friendly with a wide range of options.
- Features like scheduling and reporting.
- Many have free trials or limited free versions.
Challenges
- Full-featured versions usually cost money.
- Some apps may consume system resources.
4. Use Browser Extensions
If you only want to block sites in a specific browser, extensions are a quick and lightweight solution. Popular extensions include:
- BlockSite (Safari, Chrome, Firefox)
- StayFocusd (Chrome)
- LeechBlock (Firefox)
How to Set Up a Browser Extension
- Visit your browser’s extension or add-on store.
- Search for a reputable website blocker (e.g., BlockSite).
- Click to install or add it to your browser.
- Open the extension’s settings.
- Add the URLs of the sites you want to block.
Benefits
- Quick, easy, and free.
- Customizable blocklists, schedules, and even redirect features.
Challenges
- Only effective in the browser where installed.
- Users can sometimes disable or remove the extension easily.
5. Restrict Sites via Router Settings
If you want to block websites for every device on your Wi-Fi network, your router may allow you to blacklist or whitelist sites directly.
General Steps
- Log into your router’s web interface (usually 192.168.1.1 or a similar address).
- Look for Parental Controls, Access Restrictions, or Website Filtering.
- Enter the addresses of sites to block.
- Apply and save your changes.
Benefits
- Blocks sites across the entire network.
- Works on all connected devices.
Challenges
- Not all routers support this feature.
- Advanced users can bypass with VPNs or changing DNS.
- Changes affect all users, not just one device.
Practical Tips for Website Blocking on Mac
- Combine Methods for Extra Security: For example, use Screen Time alongside a browser extension or app for layered protection.
- Protect Settings with a Password: Especially when kids have access.
- Test Blocks After Setup: Visit blocked sites in different browsers to ensure they’re truly inaccessible.
- Keep Your System Updated: Updates can change how some blocking methods work.
- Communicate Boundaries: Discuss web restrictions with family or colleagues so everyone understands the reasons and respects the limits.
Cost Tips
- Free Options: Screen Time, editing the hosts file, router controls, and most browser extensions are free.
- Trial Versions: Many of the best website-blocker apps offer free trials. Test before you buy!
- One-Time vs. Subscription: Check pricing models. Some apps require a one-time purchase, while others are subscription-based.
- Bundles: Some productivity bundles (like those for students or families) may include web-blocking tools at a discount.
Common Challenges and How to Overcome Them
- Tech-Savvy Users Circumventing Blocks:
- Use password protection and combine restrictions on multiple levels (e.g., system + router + browser).
- Needing to Block Only at Specific Times:
- Choose an app with scheduling or use Screen Time’s scheduled downtime feature.
- Blocking Only for Children, Not Adults:
- Use child-specific user accounts with parental controls enabled.

Frequently Asked Questions (FAQs)
How can I block websites on my Mac without installing extra software?
You can use the built-in Screen Time parental controls to block specific websites without any extra downloads. Alternatively, you can edit your Mac’s hosts file for a free, manual solution, though this requires admin access and a bit more technical know-how.
Will website blocks affect all browsers on my Mac?
Blocking at the system level (with Screen Time or hosts file edits) will affect all browsers. Blocking with a browser extension only impacts that specific browser. Choose your method based on the coverage you need.
How do I unblock a website after blocking it?
To unblock a site, simply remove it from the “Never Allow” list in Screen Time, delete or edit the line in your hosts file, or remove it from your blocklist in your chosen app or extension. Always test to confirm unblocking took effect.
Can my child or another user bypass the blocks?
Savvy users may find ways to get around simple blocks, especially if they have admin access. Use passwords, combine several blocking methods, and monitor usage to make circumvention much harder.
Is it possible to block websites only during certain hours?
Yes! Screen Time and many third-party apps allow you to schedule blocking for specific times of day. This is perfect for study hours, work time, or bedtime.
Blocking websites on your Mac doesn’t have to be complicated. With these tools and tips, you can create a safer, more productive digital environment—customized to your unique needs.
