App Store - Your device or computer could not be verified in OSx86 10.7 (Lion) Posted November 28, 2011 I had this issue on all my machines, two with GA H67M-D2-B3 (v1.0 with ALC888b audio codec, and v1.1 with ALC889) and the third with GA Z68X-UD3H-B3. All machines are ordinarily wifi only using the Broadcom BCM94322MC Mini PCI-e Card # 4873300-001 (eBay - $20) in a PCIe to MiniPCI adapter (AMZN - $18). This provides OOB Airport with full AirDrop functionality and 2.4 or 5 gHz speeds. In both cases in Network Preferences the card was incorrectly seen as 'Ethernet' but with the usual Airport fan in Network Preferences. It seems from reading the related threads that the AppStore wants to have Ethernet recognized in Network Prefs, so I did the following: Deleted Library/Preferences/System ConfigurationNetworkInterfaces.plist and shut down Pulled the Broadcom PCIe card Connected wired broadband with a cable to my Airport Extreme Started-up, deleted any choices in Network Preferences, and set up wired broadband in Network Preferences by clicking '+' and 'Ethernet' Powered off and reinstalled Broadcom card Unplugged wired broadband Restarted and added WiFi as second choice in Network Preferences (the first, 'Ethernet', in now inoperable as the connection has been terminated, and appears red. I left it in place). AppStore is now fully usable for downloads and updates. The 'Ethernet' is show as 'Ethernet' by default, not as Ethernet en(0). Only the v1.1 GA H67M-D2-B3 machine required the PCIRoot=1 (not PCIRootUID) lines in the plist file. All three machines have the EthernetBuiltIn=Yes lines. All three use stock DSDT.aml from the TonyMac DSDT database.
