Thread: App Store - "Your device or computer could not be verified".

Hi guys

I have a Marvell 88E8056 Kext for my ethernet which works fine. But app store doesn't work and gives me this error message.

I have tried everything to fix it!
Removing all adapters in network,
deleting library>preferences>system configuration> NetworkInterfaces.plist
Rebooting
Adding adapters (en0) first..

Also tried adding this to boot.plist..
<key>PCIRootUID</key>
<string>1</string>
<key>EthernetBuiltIn</key>
<string>Yes</string>

No luck..

Please help!

Error message:

No i haven't tried that because it fixed my graphics card fan which was running hot remember? ( http://www.kexts.com/video-graphics/...high-lion.html )

Should i try =0? I am currently using =1 to fix graphics card fan speed.

Thanks!

I tried reinstalling and using another kext too.. Hmmm..

I'm trying to add EFI string (device ID) to boot plist now..

Ok i just fixed this one myself!! (well by researching the net)..

For anyone else with similar symptoms, the ONLY way to fix this (in my case anyways) was to add the EFI string for ethernet card to the boot.plist..

To do this i:
- downloaded EFI Studio, selected Ethernet, selected Add Device. Then clicked write to com.apple.boot.plist.
- Then went to /Library/Preferences/SystemConfiguration/apple.com.boot.plist and selected the new key and string it added.
- Then coped this string and pasted into the /Extra/apple.com.boot.plist file and saved.

Then important STEP!
- Remove all network devices from System Preferences/Network.
- Delete deleting library>preferences>system configuration> NetworkInterfaces.plist file.

* Finally, Reboot.

After reboot, go to System Preferences/Network add add devices. Click (Ethernet) FIRST!! Then add the other adapters you use to connect to the internet.

Voila. App Store now works

Hope this helps someone somewhere

Congratulations and thanks for the feedback!!!

This also happened to me, but I'm using a Wi-Fi adapter. How can I solve it?

Later Edit

Worked from Ethernet.

Same method i think..From what I understand as long as Ethernet is added first, it will work as this is what App Store checks for!

So do the same thing, then add your wireless adapter only after you have added "Ethernet" in System Preferences/Network.

and let us know!

Worked from Ethernet cable

Nice one! So are you using Ethernet instead of WiFi now? You can probably just add your Wifi adapter and unplug ethernet now! Glad it worked for you
