How to block Twitter on MacBook Air

You want to block yourself from accessing a website?

It seems to me that you simply don't load it (or any other website), but if you want to macOS to prevent you from doing that, Set up Screen Time for yourself on Mac - Apple Support and add that website to the Restricted list.

Excerpt:

To specify restricted websites, click + below the Restricted list, enter the website URL, then click Done.

... but you could just as easily un-restrict it, which makes little sense to me.

On the other hand if you want to prevent someone else from accessing it or some other websites then I believe you should investigate Parental Controls.

Hi,

I'm not sure why you want to block Twitter(X.com), though you can block Twitter (X.com) on your MacBook Air using built-in Screen Time settings, the host file, or third-party productivity apps like SelfControl.

Blocking Twitter on a MacBook Air:

You can do so using Terminal. It is not only good for parental control; but, also for keeping yourself from visiting sites that you may be obsessed with. See my User Tip: Website Management - Using Terminal to Restrict a Website from Opening: - User Tip

As Mentioned in my User Tip:

IMPORTANT: Be certain to create a Time Machine Backup of your Mac prior to performing all of this. That way, you can have something to restore from the Mac from, should anything go wrong with the new configurations.
