SD cards are great for storage of digital media, like photos or video clips in digital cameras, camcorders, MP3 players, and phones. Below are some of the reasons these cards may not work with a computer. If the SD card does not work with your device (e.g., camera) and does not work with a computer. The cards are recognized when using a USB adaptor, and also work fine in my wife's MBP SD card reader, so I know it's not the cards. System Profiler recognizes the internal card reader on my system. I've tried resetting the SMC and reformatting the cards but nothing has worked so far.
So I've got a MBPr 2012, and recently I noticed that the SD card reader won't detect SD cards. I first noticed it on Windows and thought perhaps it was a driver issue, but then I booted into OSX and the SD cards still refuse to mount. I cleaned the slot with compressed air, reset NVRAM and SMC, and finally I did the extensive hardware tests in Apple Hardware Test - which by the way didn't find anything wrong. But the SD card slot still won't work.
Sdhc Card Reader Not Working
What could the issue be? I have AppleCare for this Mac, but I believe it's about to expire (bought for Christmas 2012, Apple Care was for three years IIRC) and I also live in Puerto Rico, so there are no Apple Stores here. What can I do?
Sd Card Reader Not Working For Mac
EDIT:
Now it works!
I had to shove it in and out of the card reader a couple of times for it to work. Since I have a 128 GB card, I guess it just took a while to detect the entire thing. So I just waited for a couple of seconds and it showed up.
