VirtualBox doesn't start on MacOS High Sierra I installed VirtualBox from here: https://www.virtualbox.org/wiki/Downloads on macOS 10.13.3 and I am an admin on the computer. When I try to run the application it does not start. I tried to reinstall the application, but nothing changed. What am I doing wrong?
These two commands solved my problem:

sudo chown root:admin /Applications
sudo chmod o-w /Applications


I didn't have the right permissions.
