How To Block Internet Access To Apps On Mac

[Use Mac Firewall To Block Incoming Connections]

Connecting to the internet is one of the most fundamental features of any application installed on you computer. Whether it be to access basic information, download updates or for anything else imaginable.

However, while accessing the internet isn’t that big a deal, getting accessed from the internet can be a cause of alarm for a lot of users, as outside access to your apps can be used to steal information from your system.

Thankfully, under the Firewall feature on Mac, you can easily block incoming connections to all the apps you want, so that noone can access your information from outside.

To use this feature, follow these steps:

  1. Open “Settings”.
  2. Select “Security & Privacy”.
  3. Under this section, select “Firewall”.
  4. Turn on your Firewall if you haven’t done so already.
  5. You will be asked for your “Account Password” to make any changes permanent.
  6. Click on “Firewall Options”.
  7. In the popup that appears, you will see a list of all the apps that are being access from outside.
  8. Access to the app will be indicated by a green light, as well as a status message saying “Allow Incoming Connections”.
  9. Click on the “Double Arrow” sign for the app you want to block incoming connections for.
  10. Select “Block Incoming Connections” from the drop down menu.
  11. The status will change to what you selected, while the green light will turn to red.
  12. Save the changes and close the Settings app.

With these simple steps, you will be able to easily control which apps can receive incoming connections from outside.
