How to continue the installation on High Sierra 10.13

  1. If you have High Sierra or a newer macOS version, you will be notified that a system extension signed by Bitdefender has been blocked. This is not an error, just a security check. Click on OK.

The notification appears because of a new feature introduced with High Sierra. This feature enforces that only kernel extensions (KEXT) approved by the user will be loaded on a system. When a request is made to load an extension that the user has not yet approved, the request is denied and macOS displays an alert similar to the one shown below.

  1. To help you with the setup, Bitdefender will display a window listing the steps necessary in order to run Bitdefender properly. Click the Security & Privacy link.
  2. This will open Security & Privacy. Click the lock icon in the bottom left corner to make the changes. When prompted, enter your macOS administrator password, then press Unlock.
  3. Click the Allow button, in the lower part of the window.

Or select Bitdefender from the list, then click OK.

Congratulations! You have successfully installed Bitdefender Antivirus for Mac on High Sierra.

Congratulations! You have successfully installed Bitdefender on Mojave, Catalina, or Big Sur.
