I was wondering if it is possible to upgrade my AirPort Card so my MacBook can support Continuity features. I know my MacBook only has two antennas and the 2011-2012 cards have three but could I possibly install an extra antenna or use the card without the third? Thanks.
Sorry Broadcom never made a 802.11ac adapter that fits into the clutch cover which is where your AirPort card is located. Review this IFIXIT guide: MacBook Pro 13" Unibody Mid 2010 AirPort Card Replacement The 15" model is different! As you can see here: MacBook Pro 15" Unibody Mid 2010 AirPort/Bluetooth Cable Replacement. In that case if you can find it a BroadCom BCM94331PCIEBT4CAX board will work.
