If you are using Moutain Lion Hackintosh and try to connect to App Store you may get error like “An unknown error has occurred”.
When you trying accessing other native applications, you will get errors like below
iCloud
Unable to sign in because of a problem communicating with iCloud.
Try signing again.
FaceTime
The server encountered an error processing registration. Please try again later.
Messages

Technically, this is because in NetworkInterfaces.plist it shows
IOBuiltin
Fix
1. Download EFI Studio
2. Extract and launch EFIStudio-1.1 App
3. Select Ethernet from the Select Device: drop down.
4. Click Add Device, the Editor will be displayed.
5. Now open the org.chameleon.Boot.plist file located in /Extra directory with TextEdit.
6. at the end, you can see something like this
</dict>
</plist>
7. now add
<key>device-properties</key>
<string>key will come here</string>
before
</dict>
</plist>
8. switch to EFI Studio and from the Editor window click the Hex String to Clipboard button.
9. replace “key will come here” with copied value
10. re-boot and you can now access app store and other apps without any problems
If you come across, any other problems… write in comments
