On macOS, launchd is used to start the autostart service. An example configuration file can be found in /Applications/VirtualBox.app/Contents/MacOS/org.virtualbox.vboxautostart.plist. To enable the service copy the file to /Library/LaunchDaemons and change the Disabled key from true to false. Furthermore replace the second parameter to an existing configuration file which has the same format as on Linux, see .

To manually start the service use the following command:

# launchctl load /Library/LaunchDaemons/org.virtualbox.vboxautostart.plist
