  13. Copy the PILIST file to the LaunchDaemons folder.

    cp -rp com.solarwinds.swlemagent.plist /Library/LaunchDaemons/
  14. Change the permissions on the PLIST file.

    chown root:wheel   /Library/LaunchDaemons/com.solarwinds.swlemagent.plist
    chmod 644 /Library/LaunchDaemons/com.solarwinds.swlemagent.plist
  15. Restart the computer.
