Hi guys! I have a Kingston SHDC Class 10 with 8GB and whenever I insert in on my rMBP it doesn't recognize it. I thought the problem was with the card reader however when I tried a Kingston SDHC Class 4 it worked as it should. Any tips on how to solve this? More info: 1. My Canon can read the card just fine. 2. When I reboot the rMBP with the card inserted it just stay indefinitely stuck in the logo with a rotating symbol below. 3. Already tried both SMC and PRAM resets.
