“Allow Bitdefender SRL” in Security and Privacy does not appear

When you install Bitdefender Antivirus for Mac for the first time, you should receive the notification below.

The notification appears because of a new security feature introduced with macOS 10.13  High Sierra (additional info available here)

This applies for the Bitdefender installation as well.

Bitdefender will display its own window that will guide the user through all the necessary steps to approve the Bitdefender kernel extensions. These Bitdefender kernel extensions are essential in protecting your data.

Following the instructions in the window displayed by Bitdefender, you will reach the window below, which presents you with the option to Allow the Bitdefender kernel extension. By clicking Allow, you will complete the Bitdefender installation steps and you will benefit of the full Bitdefender Antivirus for Mac protection.

In some cases, you might encounter one of the situations below:

1. You click the Allow button, but nothing happens.

This can be found at /Applications/Utilities. Don’t worry if you’re not familiar with the Terminal, we will get you through each command:
