I've done quite a bit of research...yet STILL can't seem to find the solution to my problem. I keep getting this error, "Your device or computer could not be verified. Contact support for assistance." I have a working ethernet card. I'm kind of at a loss right now. If there's any information you'll need to further help me out, I'd be happy to get it to you, PLEASE HELP!!!:banghead:

Make sure your Ethernet is marked built-in (EthernetBuiltIn=Yes) and is at 'en0' (first net interface added).
 
Yes indeed! Everything seems to be in order RehabMan.
 
Is this what you need!?

It is at 'en0' but it is not built-in...

You also have a second Ethernet (or WiFi.. broadcom) which can confuse things...

Or it could be that the PCIbridge gets in the way. There is probably a way with DSDT edits (assuming you're using EthernetBuiltIn=Yes already).

Or you can use NullEthernet: https://github.com/RehabMan/OS-X-Null-Ethernet
 
I have 2 Ethernet ports...one of which is built in to the motherboard...the other of which is one that I had to install in order to get the Ethernet to work...

"Or it could be that the PCIbridge gets in the way. There is probably a way with DSDT edits (assuming you're using EthernetBuiltIn=Yes already)." - What would be the fix this way!?

"Or you can use NullEthernet: https://github.com/RehabMan/OS-X-Null-Ethernet" - I think I tried this before, but it was a little confusing for me to figure out=/...

It is easier to use NullEthernet than to workaround the PCI-bridge issue with DSDT edits...
 
I tried to use the NullEthernet...but I ended up with a kernel panic and had to reinstall my operating system. I now have a fresh install and I'm back up and running. Is there any way that you could help me with a step by step process of installing the NullEthernet?! I think I messed up last time when I moved the ssdt-rmne.aml to my Extra folder and renamed it as DSDT.aml. Please help!? Thanks for all of your help so far!!!

The process is described in the README.

That would certainly be a mistake...
