Dear Friend— do you still have any of these adapted wi-fi cards for sale? I am using a 2012 15" MacBook Pro 9,1 model (with Mojave no less) that has developed intermittent recognition of the wi-fi card. After it heats up a littte it sees the card, but if I am going deep into its guts to deal with a connection I would just as soon kick up its connection speeds while I'm at it. Many Thanks from Glen....
