SD Card not being recognized by macbook air. what do i do?
I have a Nikon D5100 and i was taking some photos and videos outside. so like any other person, i put in the sd card into the slot, but it doesn't recongnize the sd card! this is really annoying me. also, the camera-to-computer usb isn't working either! it was just working last week so what's the problem?
MacBook Air, OS X Mountain Lion (10.8.3), I always have the latest version.
