"An error has occurred while trying to create a virtualbox host-only network interface" (macOS)

Julien

Important

This issue may be due to security restrictions in macOS which blocks VirtualBox modules installation:

uninstall VirtualBox (use the VirtualBox_uninstall.tool of the VirtualBox downloaded dmg from https://www.virtualbox.org/wiki/Downloads).
install it again executing VirtualBox.pkg. At the end of the install, go to System Preferences > Security and Privacy, and then click the Allow button.
