Im sitting in class right now, but I can send you links to the guides I used as a general outline. One thing to note is that I own a desktop computer that has a mpcie slot in it that also had linux on it at the time. This is what I used to rebrand the card. Also whatever you do do not get one of the cards that also has bluetooth in it. I happened to have one of those cards on hand, and I could not get that to work no matter what I tried. Ordered one without bluetooth on Amazon for like 10 bucks and had it working in under 10 minutes once I got the card.
Long time since I've been on this machine or thread. As an update, the x230 is running 10.12.2 quite well. I have not attempted the audio as of yet, but will be doing that right now. The rebranded wifi card with the fakepciid its still working beautifully. I will warn anyone that wants to rebrand a wifi card to get past the whitelist, that doing this basically makes is useless as a windows machine (unless someone knows how to redirect irq and whatnot in windows drivers (I am not interested enough to even try)). If I get the audio working I will let you guys know what I did.
