Porn blocker is a tool that helps block access to porn content.

Below is a list of Mac porn blocker along with their features, pros, and cons to help you pick the best porn blocker for Mac that fit for your needs.

Cisdem AppCrypt, the best website blocker and app locker for Mac, does an excellent job of blocking access to inappropriate content and other unwanted content. It’s easy to use, feature rich and effective. And there’s a lot of flexibility and customizability.
1. Download and install AppCrypt on your Mac.
2. When you first open it, set a password. It is recommended to select the Launch at System Startup checkbox.
3. In the menu bar, click the lock icon and choose Open Main Window.
4. Enter the password and you will see the main window.
5. Under the Web Block tab, manually add porn site URLs such as pornhub.com to the top box. Click Add.
You can add words to the block list too, such as adults, porn.
Also, you can click the Import dropdown menu and choose the Porn Sites category to block.
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.
Note: To curb one’s own porn addiction, one can ask someone else (such as a trusted friend or family member) to set the password in step 2.
If you want to temporarily stop the entire blocking, you can click Disable Web Block, which requires the password. To remove an item from the block list also requires 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.
Games and apps that contain sexual content or nudity or other inappropriate content are unsuitable for children. Such as Whisper, Snapchat, Roblox, etc. Some inappropriate content can be easily seen in these apps. 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.
This tool provides 2 ways to import the porn site category to block. The first way is what I mentioned in step 5, which follows the schedule you set. This means, if you set a general schedule to block sites at certain times, porn sites on your block list will also only be blocked during the time you set. In addition, the blocking will temporarily stop when you click “Disable Web Block” from the menu bar.
If you want to block all porn content permanently, unaffected by the schedule feature and the Disable Web Block button, you can use the Always Block feature. Under the Web Block tab, click Exceptions in the bottom right corner. Go to the Always Block tab. click Import and choose the Porn Sites from the drop-down menu. Now porn sites are completely blocked on your Mac.
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.
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, uncheck the box for allow 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.
If it’s not enough, you can click Customize and manually add porn websites to the Restricted list.
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.
Screen Time let you limit adult websites on your Mac. If you child has his own device, you need to use his device to set it up. Fortunately, Apple introduced a Family Sharing feature, which allows you to invite your child’s account to join your Family Sharing group and easily manage his online activities on your device. To enable Family Sharing, click the Apple menu and choose System Preferences. Click your name then choose Family Sharing. Click Set Up Family. Then follow the prompt to set it up for your kid’s account or create a new one for him.
Tip 2: Block porn via Parental Controls on macOS 10.14 or earlier
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. It’s on Apple menu > System Preferences. 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.
Compatibility: All Mac computers with Chrome, Firefox or Microsoft Edge installed
If you don’t like to use apps, there are some extensions with porn-blocking function that can be added to Mac browser. I recommend this porn blocker to you according to my using experience. BlockSite 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.

2. Once you add the porn blocker to web browser, click the Extensions icon on the tool bar. Usually it is on the upper right corner of the window.
3. Click BlockSite from the extension list.
4. 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.
5. Go to the Block Sites section, click Add to Block List. Type the URLs of porn sites you want to block to the top box. Click the Plus icon.
6. You can also go to the Categories tab and click the Plus icon next to Adults category.
7. Click Done.
It’s recommended to 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.
The default web browser for Mac computers is Safari. Therefore, you may need an extension to block access to pornographic content on Safari on Mac. Porn Block Plus is a Safari porn-blocking extension, which protects you or your family from porn sites and explicit content on Safari.
To make the blocking more effective, it’s recommended to uninstall any other third-party web browsers on Mac. Since this extension only works in Safari.

5. Then Go to Safari > Preferences (or Settings).

Apply to: Routers with web filtering
If you would like to block pornography and inappropriate content from all or some of your home devices, the easiest way is to find your router’s built-in web filtering settings. While some routers don’t have such settings, many routers are able to restrict access to certain web content. Some of them even allow you to restrict porn sites with a few clicks. It all depends on what router you have. For example, if you own an ASUS router, its AiProtection might be of help to you.
1. Login your router on a web browser.
2. Find AiProtection from the left sidebar. AiProtection is a tool added to ASUS router that provides home network security. You can restrict unwanted websites and apps on it.
3. Go to Parental Controls. Enable the Web & Apps Filters switch.
4. Click the Client Name drop-down box. Select the device you want to set restriction. If your family has multiple devices need blocking porn, repeat these steps to set up restrictions on all devices. But you should make sure the devices are connected to the Wi-Fi router.
5. Go to Content Category tab. Check the box next to Adult. Tap the plus icon then click Apply.
This method not only can block porn on Mac, but also works on all other devices that are connected to the router. Many other home routers such as TP-Link, NETGEAR also have porn blocker. The settings may be little different.
In addition to using a porn blocker, here’re some things you can do to restrict access to porn or inappropriate content on your Mac.
Turn on SafeSearch on Google
Google Search is the most popular search engine. You may worry that your child stumbles upon adult content and explicit images when he or she uses Google Search. To prevent this, you can use Google’s SafeSearch filtering. It will help hide explicit content like pornography from search results.
To turn on it, go to Google SafeSearch page. Select Filter or Blur according to your needs.
Turn on SafeSearch on Bing
Bing also has a Safe Search mode that filter out explicit search results like porn from search results. If you frequently used search engine is Bing, turn its SafeSearch on.
Go to bing.com on your browser. Click the 3-line icon in the upper right corner of the window. Click SafeSearch. There’re 3 options for you to choose: Strict, Moderate and Off. Select Strict, which will filter adult text, images, and videos from your search results. Click Save at the bottom of the window.
Enable Restricted Mode on YouTube
YouTube bans adult content, but some users report they can still see some videos that contain mature content. This is because some users can skirt the platform’s rules and upload inappropriate videos. Many parents are worried about this and want to make YouTube safer for kids. Restricted Mode on YouTube helps hide potentially mature videos.
To turn it on, go to youtube.com and log in. Click your Profile icon in the upper right corner. Click Restricted Mode and activate this mode. Note that the settings only apply to the specific browser you set up. And if you log out, the blocking will not work.
