With Focus, you don't need to use the macOS terminal or edit your hosts file, it's simple to block sites on all major web browsers like Safari, Chrome and Firefox with just a few clicks.
To get started, click the Focus menubar icon, then select Preferences in the drop-down menu.
Then select the Blocking panel from Focus Preferences, Focus should look like this:
Focus makes it incredibly easy to customize your blocked websites!
To add a blocked website click the plus + icon at the bottom of the screen, enter the website and hit enter.
To remove a blocked website, click the minus - icon, and Focus will remove the selected distraction.
To edit an existing blocked website, just double-click it, change it to whatever you want, and hit enter.
When you're in the zone, and end up on a distracting website—you need to be able to block it quickly.
Focus supports dragging and dropping URLs onto the Focus menubar icon to add new blocked websites quickly.
This even works in Hardcore Mode when you can't access preferences.
In addition to blocking websites, you can tell Focus to only allow certain websites:
Switching Focus to Allowed Websites with an empty list blocks the entire Internet. You can add rules, and instead of those websites being blocked—they'll be allowed.
If you need to manage your blocked websites, you can export them, import a new list, or reset them back to the Focus defaults.
