You need to uninstall a Symantec product for Macintosh. You have tried several methods, including manually uninstalling or running the Symantec Uninstaller without success. Alternatively, you have been referred here by a technician or from another document because running the RemoveSymantecMacFiles utility is necessary to solve a problem with your Symantec program for Macintosh.
WARNING: RemoveSymantecMacFiles cannot silently/remotely remove the new *.systemextension present in SEP 14.3.5323+ (RU2+) and macOS 10.15 Catalina and newer. RemoveSymantecMacFiles must be run locally and will prompt for local administrative credentials to uninstall the *.systemextension when the script moves the SEP application to the Trash. Failing to do so will result in a corrupt SEP installation and possibly broken networking. Contact technical support if an unattended/silent uninstallation is necessary.
Apple Macintosh OS X or macOS
WARNING: RemoveSymantecMacFiles does not target a single Symantec product. It removes all files and folders for ALL Symantec and Norton products for Mac, including any contents you have created yourself within those folders.
