Thanks for fast reply. I tried both of them. I tried adding verified serial and random serial from chameleon wizzard. (I tried macpro 3,1 and iMac) But still nothing. No, I don´t have smbios from the old instalation.
BTW, I know, that I have to choose similiar system as macpro 3,1 or something like that. but I have AMD. So what do you prefer?
