Hi again friend !

Well I know *but * Ive tested with another card NVIDIA ( more cheaper ) Not Xfx and the system do the same so I'm thinking is something else going on . :-(

You said on FB that should try only with drivers and kext . Can you explain this better ? I know what kext are but what do you mean with drivers in this case ? Wich ones ?

Thanks !
