What are the “System” Rules?
The System Rules are the various rules that allow Mac OS X to continue to function properly. Nothing (besides sanity) prevents one from modifying these rules, but care should be taken, because several of them are absolutely necessary. Modify at your own risk. Don’t come crying to me. If you accidentally delete or otherwise modify these, you can simply quit GlowWorm remove the system.rules file from ~/Library/Application Support/GlowWorm FW Lite/Rules/system.rules and then start GlowWorm again. You will be prompted to re-install that missing file. It should then be back to the “factory default”.
