Responder a:Can I use its 802.11ac AirPort Card on my RMBP 15 (mid2012)?Hi, Everyone. ^^ As you know, RMBP 15" Mid 2012 had installed Airport card, BCM94331CSAX (Support 802.11a/b/g/n) RMBP 15" Late 2013 has installed Airport card, BCM94360CSAX (Support 802.11a/b/g/n/ac) BCM94360CSAX has same demensions(? looks same), 3-antenna ports, and interface connection between BCM94331CSAX. I just installed BCM94360CSAX in RMBP 15" Mid 2012 basic model, last weekends. Wi-Fi Link speed is 1Gbit/s with ac mode, right now. (450Mbit/s with n mode, past) It works very well and still using AC mode without problems. As a results, RMBP 15" Late 2013's 802.11ac airport card is compatible with RMBP 15" Mid 2012. But, I don't know there are any technical issues.
