So here's my issue. I have a MacBook with no sd card reader. My hp printer has one built in so i've always used that. I haven't had to use it for anything in a long time but now i got a digital picture frame so i need it. I have 2 sd cards, neither of them are recognized by my computer anymore. I figured it might be a problem with the card reader on the printer, so i went on ebay and bought a card reader there, that won't work either. I have a hard time believing both sd cards are faulty. What are my options here?
