Also, in step 6, you can click Import and choose Porn Sites, which will add all popular porn sites to the Block list.

Now all the websites on the Block list are blocked on Safari, Google Chrome and other browsers on your Mac by the password you set. They are inaccessible.

To unblock them, one needs to disable WebBlocker or remove them from the Block list. Both approaches require the password. If your kid or someone else tries to access the blocked porn sites with an incorrect password, AppCrypt will record the failed attempt with date and time and capture a photo.

Tips

Block access to inappropriate apps on Mac

Games and apps that contain sexual content or nudity or other inappropriate content are unsuitable for children. If there are such apps on your Mac and you don’t want your kid to access them, just lock them with password. Choose the App Lock tab, select the apps and click Open.

Choose the App Lock tab

Keep porn away completely with the Allow list mode

There are two modes: Block list (default) and Allow list. The former allows you to block specific sources of porn. Alternatively, you can use the Allow list mode to block all websites excluding a few. This way, your child can only access the websites approved by you.

Block access to websites and apps only during certain hours

Besides blocking porn on Mac permanently, you can schedule specific times. Click the Schedule icon  and set one or more general schedules (which apply to all blocked sites). Or, you can set the custom schedule for individual blocked sites.

#2 Screen Time

Compatibility: macOS 10.15 Catalina or later

With Apple’s Screen Time, you can easily set limits on Mac, iPhone and iPad. It allows you to block porn on Mac by limiting the use of websites and apps or by only allowing certain websites. You can set age-appropriate restrictions and use a password to help enforce the restrictions. Also, this porn blocker for Mac tracks how much time children spend on applications, from social networking apps to gaming apps.

How to block porn on Mac with Screen Time

1. Open System Preferences and choose Screen Time.

2. In Options, turn on Screen Time.

3. Create a passcode, which is used to prevent the porn blocking from being removed.

4. In the sidebar, click Content & Privacy. Click Turn On in the top right corner.

5. Under the Content tab, disable Explicit language in Siri & Dictionary.

6. Under the same tab, enable Limit Adult Websites, which will automatically limit access to websites considered inappropriate by Apple on your Mac.

enable Limit Adult Websites to block porn sites

If it’s not enough, you can click Customize and manually add porn websites to the Restricted list.

Note that the auto block only applies to Safari. Also, it often goes too far and blocks normal websites.

With Screen Time, you can also limit apps on Mac. Choose App Limits in the sidebar and turn it on. Add app categories such as Games and Social Networking (which may potentially contain porn content). Set limits on the apps.

#3 Parental Controls

Compatibility: macOS 10.7 Lion - macOS 10.14 Mojave

If your MacBook Air, MacBook Pro or iMac etc. is running macOS 10.14 or earlier, then Screen Time is not available. But don’t worry. You have Parent Controls, a built-in feature similar to Screen Time. You can use this free built-in porn blocker for Mac to make sure inappropriate applications and websites (porn, pay-to-play games, drugs, etc.) are blocked.

Note that Parental Controls doesn’t apply to an administrator user account. If you want to block yourself from porn, consider the first method.

How to block porn on Mac via Parental Controls

1. In System Preferences, choose Parental Controls.

2. Click the lock icon at bottom-left corner and type in the password to unlock Parental Controls preferences.

3. Create a user account for your child to apply Parental Controls.

4. Under the Apps tab, check the box for Limit Applications on this Mac. Only allow apps that you think are porn-free and appropriate for your child.

5. Switch to the Web tab. Click Try to limit access to adult websites.

6. Click Customize to customize porn blocking if needed.

You can customize by adding porn site addresses to the Never allow these websites list. Don’t forget to click OK to save your settings.

#4 BlockSites

Compatibility: All Mac computers with Chrome, Firefox or Microsoft Edge installed

If you don’t like to use apps, there are some extensions with blocking porn function that can be added to Mac browser. I recommend 2 to you according to my using experience. BlockSites does well in blocking porn on Mac without taxing your system in the process. Not only can you block porn sites by typing the web address or select categories to block, but also can block URLs containing specific words or phrases. Plus, this porn blocker for Mac allow you to set a password to protect your settings, helping you better control porn access on Mac.

But according to my trial experience and user reviews, it has some drawbacks.

  • Kids can disable the porn blocker for Mac with ease even if I have set the password.
  • Adding more than 6 sites to the block list requires purchasing the upgraded version.
  • Most advanced feature such as password protection and custom block page also charges.
  • It fails to block websites such as twitter.com (where porn is available).
  • It uses too much CPU power.

How to block porn on Mac with Site Blocker

1. On your Mac, install this extension to Chrome, Firefox or Microsoft Edge.

2. Once you add the porn blocker for Mac, click its icon on the toolbar.

3. From the pop-up dialog, choose Edit block lists. You can also click Block this site to block current websites directly, but you have to open all the porn sites that you intend to block.

edit block lists

4. In the Block sites tab, define a list of porn sites. You can block sites permanently or by schedule.

5. There are 3 modes to strengthen the block:

  • Go to the Categories tab on the left menu bar to select Adults and enable it.
  • Go to Block by words to input the keyword like “porn” “adult” “18” “sex”.
  • Go to Custom Block Page to create your own blocked page. I think this step is necessary because the original page will appear a prompt: “This site is blocked by BlockSite”. This would allow kids to disable it more easily.

#5 FoxFilter

Compatibility: All Mac computers with Firefox or Chrome installed

Available as an extension for both Mozilla Firefox and Google Chrome, FoxFilter is a free Internet filter to detect and block pornographic and other inappropriate websites. You can use it to easily block porn on Mac. It’s easy to set up and configure.

But as with other extensions, this one can be removed from your browser, which means one can easily get around the blocking.

How to block porn on Mac via FoxFilter

1. On your Mac, install FoxFilter on your Firefox or Chrome.

2. Open a random website. Right-click and choose FoxFilter Settings.

3. Click the Change Limited Settings button.

4. Now you have access to FoxFilter settings. Go to the Sensitivity tab.

5. There are 4 options through which you can control how this porn blocker for Mac identifies porn websites. Selecting all 4 options will apply the strictest adult content blocking.

the Sensitivity tab

6. Go to the Blocked tab. FoxFilter already automatically blocks access to many websites and webpages containing porn content on your Mac browser. You can edit the Blocked Keywords & Sites list to block more.

the Blocked Keywords & Sites list

I think FoxFilter does better than BlockSite on this feature. Entering the keywords such as “porn” will instruct FoxFilter to block any page that contains this specific keyword. While most other extensions can only block URLs containing specific words or phrases.

Final thought

We’ve looked at how to block porn on Mac. Whether you are going to prevent your children or yourself from seeing porn content, distracting videos, games, or social networking sites etc., a content blocker is needed all the time.

It’s possible to remove bad websites by editing your hosts file in Terminal, which is not a good idea because it involves editing system files. This article recommends 5 porn blockers for Mac. The best one is Cisdem AppCrypt. It’s more flexible, professional and feature-rich when compared to free and online porn blockers.
