Ok, I got a new Mac Pro in December of 2007 that came without an Airport card installed. I'm now looking into getting one to install myself, however I'm a bit confused as to what card to buy. The one available on the Apple website says it is incompatible with Mac Pro's introduced in 2005. So I'm assuming that will not work. I've looked online and have found some like this with model number MB363Z/A. I THINK this is what I want, however when I enter that model number into google and search a bit I find that some websites have it listed as Airport Extreme Wireless Card for Mac Pro (2008). Now, what I'm wondering is if this will work for my Mac Pro that I got in December of 2007, or not. And if not, can anyone give me some advice or point me to the right one I need to buy? Thanks for your help.
