Simply trying to block Youtube on student MacBook Airs running the latest Catalina, using the Parental Controls config profile.



I get it it to stick perfectly in Safari. It comes up with a nice full page Screen Time Message.



However, in Chrome, which we use for Classroom etc, it is less effective. It comes up with a Screen Time Notification but underneath Chrome will still load Youtube and the Block seems one step behind.(obviously Safari is part of the OS and more friendly)



This seems really easy and straightforward, but I’m having a heck of a time. I know people suggest web-filtering solutions etc, but for the little amount we need to block and manage, we were hoping the tools we already pay for in Jamf would do the job for us.



Any suggestions are greatly appreciated.

Have a look at Chrome's URL Blocklist settings

Thanks. That looks great. Now if I understood how to package and deploy that. Is it just a script I build?

Hi @saulv, you can deploy a configuration profile payload and use "Application and Custom Settings". Make a plist file with the setting you need to enforce: URLBlocklist https://support.google.com/chrome/a/answer/7532419?hl=en



The name of the plist file would be com.google.chrome and target the endpoints. The profile will enforce this preference for Chrome. Here is a quick example:



<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

<plist version="1.0">

    <dict>

        <key>URLBlocklist</key>

        <string>https://www.youtube.com/</string>

    </dict>

</plist>

Hello @omarluna, when I make this Config profile send it to a device I see that there is an error with it when I check on it in chrome:policy.  I am needing to block this some student iMac devices. I was able to get it block on safari but firefox and chrome are a different story.

This is what worked for me.  Just used two different URLs for testing purposes. 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>URLBlocklist</key>
<array>
<string>youtube.com/</string>
<string>delta.com/</string>
</array>
</dict>
</plist>
