SelfControl is a free and open-source application for macOS that lets you block your own access to distracting websites, your mail servers, or anything else on the Internet. Just set a period of time to block for, add sites to your blacklist, and click “Start.” Until that timer expires, you will be unable to access those sites—even if you restart your computer or delete the application.


  • Mac



SelfControl is the strictest website blocker. It blocks access at the network level to all the applications using TCP/IP protocol. Even if you reboot your mac or remove the application you must finish your break.
You need to insert the password everytime you want to start the application.


How to install

  • Download from
  • unzip
  • Drag-n-drop in the Application folder
  • The first time you start it, MacOS will tell you this application was not designed by an Apple developer, you need to add an exception


Start the Application from the Application folder and set you white or black list. !!!!! White list on SelfControl is dangerous nothing using the network but the site your list will work.


Good point:

  • It is a real blocker. It is based on the network settings and any web browser can be used.
  • Free under GPL License.
  • Really easy to configure.

Bad points:

  • You need to type your password when you start it.
  • There is no way to stop it.
  • The whitelist blocks also your email

SelfControl is an application made by geeks for geeks, I would not recommend it to not-tech users.
