Its also a good habit to delete the SystemConfiguration folder if you have changed your SMBIOS type or any of the key system ID's such as MLB, ROM, S/N in your clover config.plsit file as MacOS keep copies of previous configuration 'sets' in these files which will show up as extra devices in Sys-Prefs->iCloud->Account Details->Devices which you will be unable to remove until you rebuild the Configuration Files.
rm -r /Library/Preferences/SystemConfiguration
