Hey, I have bought an airport card for a late-2009 Mac Pro (current gen) bought in September 2009 and was going to install the card myself. However, the part/model number is listed as MB363ZA/A, but i've seen some mentions that the part number is now either MB988ZM/A or maybe even MB988LL/A ? Does anybody know which will work and what is official? I phoned up an authorised Apple reseller in my city (not a proper Apple store) a few weeks ago and they confirmed the necessary part number was MB363ZA/A, and this is what they would install for about £35 (price including purchase of the card). A brand new official Apple store has just opened since in my city so I might take it in there instead. To either buy the card and have it installed, or just to install the card I already have at the official store is the same price (about £40-45). The guy I spoke to at the official store also said that the Airport card installation is in fact a user-installable option, whereas i've heard the opposite from (admittedly) anecdotal information on every forum post/article i've read on this online.
