I have my friend's Samsung microSD card/adapter to get him games and put it on there, but when it's in my MacBook Pro it doesn't recognize anything how do I locate it on my Mac?
A card has to be in the adapter before it will appear on the desktop of your Mac. Just plugging in the adapter without a card will do nothing. It won't show up on the desktop. In other words, it won't mount without inserting the card.
