If you are using a Mac with macOS Catalina installed, then you can use the built-in Screen Time controls to put the breaks on any website that you deem as unnecessary. To a lesser degree, you can also impose time limits on any site to gradually curtail an addiction.

So without any further ado, here’s how to block or impose time limits on websites using Screen Time.

Blocking Websites Using Screen Time

Screen Time in macOS Catalina works quite similarly to Screen Time on the iPhone and iPad. The functionality brings to the table several controls that help to monitor as well as control the various activities that you can perform on your Mac.

But whether you are already familiar with certain aspects of Screen Time or haven’t had a chance to check them out yet, here’s the complete step-by-step process on how to block sites easily.

Note: The following method applies not just to Safari, but also other web browsers (Chrome, Firefox, etc.) installed on your Mac.

Step 1: Open the Apple menu, and then click System Preferences.

Step 4: Check the box next to Share Across Devices if you want any configurations that you make to Screen Time to apply across all of your devices, including to any iOS or iPadOS devices tied to the same Apple ID.

You can also check the box next to Use Screen Time Passcode if you want to set up a passcode, which will help stop anyone else from making changes to Screen Time without your permission.

Time to test the restrictions that you just applied. Attempt to load a blocked website in Safari or any other browser. You won’t be able to! Do remember that you also won't be able to access any sites that contain NSFW content in addition to the websites that you block manually.

You can white-list a site by clicking the Add Website button, followed by inserting the Screen Time Passcode. If you are imposing these restrictions on yourself, this will require restraint on your part.

Imposing Time Limits on Websites

Screen Time in macOS Catalina also lets you impose time limits on any website. You can then surf the website for the given duration of time, after which it will be blocked. The whole process is a little inconspicuous, but you will find the exact process detailed below.

Note: Website time limits apply only to Safari, and not to any other browsers that you’ve installed on your Mac.

Step 1: Visit the Screen Time panel and then click App Limits. Follow by clicking the '+'-shaped icon, as shown below.

Note: You may also see a list of recently visited sites listed underneath the Websites section. If the required website is already present, select it by checking the box next to it and start adding the time limits right away.

Step 5: Insert a daily time limit for the site, and then click Done.

Note: You can also add a custom schedule for each day of the week. Click the radio button next to Custom, and then click Edit to do that.

Step 6: You will see the site listed within the App Limits section. Add time limits to any other site that you want, and then exit Screen Time.

Note: You can perform any modifications to time limits that you've already imposed from within this screen (select the website, and then click Edit Limit to do that).

Once the daily time limit is up, the site will be blocked, and you won't be able to access it anymore. You can lift the limit if you want to by clicking the Ignore Limit option (Screen Time Passcode needed), so once again, restraint is needed.

Remember that if you have the Share Across Devices option enabled within the Screen Time Options panel, any time that you spent on restricted websites on other devices will also count toward the total time limit.

Procrastinate Less

The internet is a cesspool of distractions. Kudos to Apple for providing native means to block websites easily on the Mac. Don't forget to use time limits on certain websites as and when you see fit.
