VBoxNetAdpCtl: Error while adding new interface: failed to open /dev/vboxnetctl: No such file or directory.

macOS VirtualBox Bridged Adapter 不能用

I'm running macOS High Sierra 10.13.1 and VirtualBox 5.2.2.

This worked for me:
Grant permission to VirtualBox under System Preferences > Security & Privacy > General (this request is new to macOS High Sierra)
Open Terminal and run: sudo "/Library/Application Support/VirtualBox/LaunchDaemons/VirtualBoxStartup.sh" restart

问题：And when I start I get an error: Failed to open/create the internal network 'HostInterfaceNetworking-en0' (VERR_SUPDRV_COMPONENT_NOT_FOUND). Failed to attach the network LUN (VERR_SUPDRV_COMPONENT_NOT_FOUND).

My installation environment is macOS High Sierra.

1. Install the extension package Oracle_VM_VirtualBox_Extension_Pack corresponding to the VBox version
2. Create a new virtual machine
3. Set the network to bridge the network card
4. Start and select the image installation
5. During the installation process, open [Network and Host Name], Ethernet, then you can see the LAN IP
6. Continue to complete the installation.
