I'm having some problems with the Mac App store with the driver. When I try to login, it says 'An unknown error has occurred'.
I tried deleting NetworkInterfaces.plist in \Library\Preferences\SystemConfiguration\. Then I found this thread and tried EthernetBuiltIn set to 'yes'. But this leads to a black screen before the login screen! I had to boot to installer and Terminal to remove the entry and restore the desktop.
I'm at a loss of what to do next.
Please send me you kernel logs collected with the debug build and a dump of IOReg.
