Failed to load VMMR0.r0 (VERR_SUPLIB_OWNER_NOT_ROOT) – VirtualBox Mac

So you tried installing Ubuntu on your Mac's VirtualBox and got this error:

Failed to load VMMR0.r0 (VERR_SUPLIB_OWNER_NOT_ROOT).

There probably are many causes for this error, but the one I encountered was because of /Applications not being owned by root.

To see who owns /Application currently:

$ ls -l /

If the owner of /Applications is not root:

$ sudo chown root /Applications

Try installing Ubuntu now. The problem should be gone. Happy virtual boxing!
