On macOS Launcher runs as a launchd service. It logs to the files
/var/log/kolide-k2/launcher-stdout.log These files may be viewed, or sent to support.
Launcher can be configured to log more verbose. You can do this by running the following command in a terminal window. It needs root permission, and will prompt you for your password.
sudo pkill -SIGUSR2 -f /usr/local/kolide-k2/bin/launcher
debug mode can be turned off by running that same command.
