I bought this specifically for mac, and it works like a charm. I was worried by some of the reviews mentioning different glitches, but so far so good for me. I am running Mac OS 10.8.2. I will update this review when I burn some discs, but playing and ripping blu-rays works perfectly. My only complaint would be the flimsy construction, but for the price, what can you expect.

This card works perfectly. I own a canon 60D and I have had no problems at all with this card. I shoot lots of multiple shots and video, and I never wait for the card to load. I highly recommend this card.
