Excerpt: I normally give 5 stars but my cards are not downloading clean. It's either the Apple Yosemite software or the internal SD reader on the Macbook Pro and iMac or the D800 but it's taking me way too long to get my files to download without some weirdness.
Excerpt: Always like SanDisk. But when put new card in my new Canon XS60 and took shots the camera had 60 pix but when connected to my computer, the computer only saw two. And no videos. Old cards used with new camera worked fine. Had to format the card in the camera and now works fine.
