I get the following message when trying to start VirtualBox via the command line: VirtualBox: Error -10 in SUPR3HardenedMain! VirtualBox: Effective UID is not root (euid=501 egid=20 uid=501 gid=20) VirtualBox: Tip! It may help to reinstall VirtualBox. And I see the following message when loading up the GUI: http://i.stack.imgur.com/8dBWR.png I have tried re-installing, restarting, disabling SIP on 10.11, tried installing 4.3, 4.2, and chown-ing various directories, but to no avail. Has anyone else seen anything like this, or found any workable solutions?" defect closed other VirtualBox 5.0.0 fixed other Mac OS X
