Your device or computer could not be verified. Can't Login to App Store

[mmillis1]

I have successfully installed 10.10 on my Dell Optiplex 960 with only 1 issue. iMessage, and App Store don't work with the error message "Your device or computer could not be verified. ".

I installed the quick start "easybeast" from multibeast with no issues.

In order to get ethernet working I had to install "AppleIntelE1000e v3.1.0" from multibeast.

This is just for my onboard ethernet, no wifi, no usb, just onboard.

I have tried removing all the network connections, removing the NetworkInterfaces.plist, restarting, no luck.

I have checked my serial number to see if it was "taken" from a mac already and it has not been used.

I have also tried adding the following to my boot list file:

(got the string value from EFI after selecting my ethernet device, see attached photo)

<key>device-properties</key>
<string>450000000100000001000000390000000100000002010c00d041030a040000000101060000197fff0400160000006200750069006c0074002d0069006e0000000500000001</string>

This is my "org.chameleon.Boot.plist"

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

And a photo of my ethernet card info.

I have read through many of the forums posts that try to help and have tried many of them with no luck.
