How to remove ghost Hackintosh from iCloud

So recently I had a small problem with my Hackintosh, I was testing different SMBIOS-es and didn't think about consequences of being logged in in iCloud when playing with it.

So I ended up having 2 iMac devices on iCloud and I could not delete them.

When I deleted unwanted one it reappeared in a second, so how I fixed is very simple.

I opened iCloud copied the serial number of the iMac I initially set up then opened clover configurator and in the SMBIOS panel I replaced old serial number instead of new one, then you should copy first 3 symbols of Serial number in my case it was W88 , and replace the first 3 symbols in Board Serial number on the right side in SMBios, then sign out from I cloud re-sign in and then I successfully removed the unwanted device. ( device with Latest SMBIOS. )

You can even change your iMac name in System Configuration > Sharing to easily delete the device you don't want.

So the idea is to use the serial number of Ghost device on new SMBios generated device.

Also you can delete the SystemConfiguration folder from Library/Preferences just to avoid problems with iTunes and iCloud but I didn't need to do it.
