Once you type your credentials inside the App Store you get a red text message reading, ''Your device or computer could not be verified. Contact support for assistance.'' According to the links provided below, it seems that the OS X does a simple check of the ethernet identifier to determine whether or not "your device or computer" has been verified. The system-generated /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist contains an indicator value to tell you whether or not your ethernet card is "built-in." | |||
<source lang="xml"> | |||
<?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"> | |||
<plist version="1.0"> | |||
<dict> | |||
<key>Interfaces</key> | |||
<array> | |||
<dict> | |||
<key>Active</key> | |||
<true/> | |||
<key>BSD Name</key> | |||
<string>en0</string> | |||
<key>IOBuiltin</key> | |||
<true/> | |||
... | |||
</source> | |||
If the error message comes up your value for the key IOBuiltin is most likely set to <false/>. Here are the steps to solve this problem. | |||
== 1. Get EFI string for your ethernet card == | |||
=== a. Find out the devicepath for the ethernet card === | |||
You can use a utility called gfxutil (GFX conversion utility) to find out. Version 0.71b can be downloaded from [http://michaelhan.net/public/gfxutil here]. | |||
Make sure the file is executable if it isn't already. | |||
<source lang="bash"> | |||
$ chmod u+x gfxutil | |||
</source> | |||
Then execute the file with a parameter "-f ethernet" for the devicepath. NOTE: Your devicepath will be different from mine. | |||
<source lang="bash"> | |||
$ gfxutil -f ethernet | |||
DevicePath = PciRoot(0x0)/Pci(0x1c,0x1)/Pci(0x0,0x0) | |||
$ | |||
</source> | |||
=== b. Convert the plist from text to hexadecimals === | |||
Create a plist in your favorite text editor as follows: | |||
<source lang="xml"> | |||
<?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"> | |||
<plist version="1.0"> | |||
<dict> | |||
<key>PciRoot(0x0)/Pci(0x1c,0x1)/Pci(0x0,0x0)</key> | |||
<dict> | |||
<key>built-in</key> | |||
<string>0x01</string> | |||
</dict> | |||
</dict> | |||
</plist> | |||
</source> | |||
Save it as '''ethernet.plist'''. Then convert into hexadecimal format using '''gfxutil'''. | |||
<source lang="bash"> | |||
$ gfxutil -i xml -o hex ethernet.plist ethernet.txt | |||
</source> | |||
Open '''ethernet.txt''' and copy the content of the file into the clipboard. | |||
== 2. Update the boot plist file == | |||
Your boot plist may be different depending on the bootloader. Mine is called org.chameleon.Boot.plist and it is found under /Extra folder. Open it up with a text editor and paste in the hexadecimal value as a '''device-properties''' pair. | |||
CAUTION: Don't insert it between other key/string pairs. | |||
NOTE: Your hexadecimal string may look different. | |||
<source lang="xml"> | |||
... | |||
<key>device-properties</key> | |||
<string>4b00000001000000010000003f0000000100000002010c00d041030a0000000001010600011c0101060000007fff0400160000006200750069006c0074002d0069006e0000000500000001</string> | |||
... | |||
</source> | |||
== 3. Delete all network interfaces == | |||
Go into your Network settings and delete (click on -) all of the network interfaces you have listed there. It's possible you may only need to delete the Ethernet. | |||
Delete */Library/Preferences/SystemConfiguration/NetworkInterfaces.plist*. Yes, delete it. It's auto-generated by the system during the boot process. | |||
== 4. Reboot == | |||
And enjoy. | |||
