Thanks to your guide I managed to fix iMessage but each time I use a new serial number it works for once and after I shutdown my laptop and start it again it shows me the " You cannot sign in to iMessage on this Mac at this time. To use iMessage with this Mac, contact Apple Support and provide the code below." message.
I have checked iMessageDebug output and it's the same between reboots. What's the problem?
Stop injecting new serial numbers, use one that is unique to your pc only and stick with it, then log into your iCloud account on the web and remove any with the serial numbers you've tried leaving your current one. When you try iMsg again and it doesn't logon, don't be tempted to change the S/N again just leave it as it is.
