VirtualBox error on MacOS Sierra


I am using virtualbox+vagrant for running a virtual machine for development purposes. It was running perfectly fine before I made the stupid mistake of upgrading to Sierra. Here's the trace:

nkohlis-MacBook-Pro:vagrant nkohli$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Clearing any previously set forwarded ports...
==> default: Clearing any previously set network interfaces...
There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

Command: ["hostonlyif", "create"]

Stderr: 0%...
Progress state: NS_ERROR_FAILURE
VBoxManage: error: Failed to create the host-only adapter
VBoxManage: error: VBoxNetAdpCtl: Error while adding new interface:

VBoxManage: error: Context: "int handleCreate(HandlerArg*, int, int*)" at line 66 of file VBoxManageHostonly.cpp

I tried one of the solutions suggested elsewhere:

Here's the stack trace when I ran vagrant up after reinstalling VirtualBox:

I've looked around but didn't find a similar issue reported elsewhere.

Upgrading Vagrant and VirtualBox fixed the issue for me. For those wondering, no you don't end up losing your existing VMs if you upgrade.

some reported issues after update to macos Sierra. re-installing Virtualbox solves the issue

answered on Stack Overflow Sep 23, 2016 by Frederic Henri

Solved. VirtualBox would always fail installation no matter how many times I tried. What worked for me was to reboot and try again, it worked! (Earlier, before trying to install, I had already upgraded fuse, vagrant, and checked to 'allow' Oracle to load its extensions from the System Preferences/Security panel. The key thing was the computer reboot before trying to install VB on High Sierra.

This issue affects anyone installing VirtualBox for the first time on a fresh macOS High Sierra 10.13.

This effectively breaks our fully automated installation process on macOS, since the user now has to perform a manual approval and then restart the installation (reboot and rerun the installation in some cases)

First, try to restart the Virtualbox with below command.

sudo "/Library/Application Support/VirtualBox/LaunchDaemons/" restart

If you are still facing this issue then given assign the below permission as per the screenshot. enter image description here

Note: If the Allow button does not show up, run sudo kextcache -system-caches



Run the following command in your terminal:

for bin in VirtualBox VirtualBoxVM VBoxNetAdpCtl VBoxNetDHCP VBoxNetNAT VBoxHeadless; do
    sudo chmod u+s "/Applications/${bin}"

It worked for me without upgrading anything.

NOTE: This will allow any user on your system to run any of these commands as root. Please be sure you understand what these commands mean before you run them.
