A customer states that a MacBook Pro (Retina, 13-inch, Early 2013) does not recognize the
SD card she brought with her. You have her reproduce the issue, and discover that she is
properly inserting the card and it is not recognized by iPhoto and Image Capture. What
question should you ask next to isolate the issue to hardware?
Are you running the latest version of iPhoto?
What kind of files or images are on the SD card?
Have you tried resetting your SMC and NVRAM?
Have you had this issue with all SD cards or just this one?
