Mountain Lion Issue with AppleID for example App Store

[Empusas]

Hi,

i upgraded my Lion to Mountain Lion with Unibeast and Multibeast. It wasn´t easy but now i got it done. Everything works fine. All hardware, sound, LAN and bluetooth works fine.
But when i try to logon with my AppleID, for example at the ApP store i get the message "unknown error". I can not logon to iMessages or Facetime as well.
Does anybody have the same problem. Any Idea to fix it?

In looked into the system Konsole and found this when i try to setup the icloud :

It seems to me like there is somethig in Mountain Lion that detects that this is not a real mac.
I have wipped the disk and reinstalled ML on the clean disk again. I used another MAC(real) to dowload the ML Istaller and to create the USB stick. I even ave used a different USB stick.
So i have proven that a corupted Image or a hardware problem with the USB stick can not be the root cause of this problem.

I would really like to get some more ideas how to fix it.
