that there could be a variety of attacks that could cause security problems.<br \/>\n\u3000However, if the OS is not running, the malware that attacks the OS will not be able to run.<br \/>\n\u3000However, the designers of OpenCore erase this variable at the end of the OS because it becomes a problem while the OS is not running.<br \/>\n\u3000This seems to be a design concept that
