    Automatic value generation attempts to provide the most accurate value for the currently installed CPU. When this fails, please raise an issue and provide sysctl machdep.cpu and dmidecode output. For a full list of available values and their limitations (the value will only apply if the CPU core count matches), refer to the Apple SMBIOS definitions header here.
