Macbook Retina will not read SD card with ML? Fast memory cards drop Raw frames.

[bluecosmo5050]

Hello, new user here, first post. I have a Canon 6D, I have used different cards shooting RAW video however the Mac says it can't use the device I've put in each time. I even tried it with a USB 3.0 card reader.

On the second question, I am using Lexar 95MB 1000x UHS 3 cards. That should be plenty according to what other people are using. But even at around 720p it always stops within 15 seconds.

Your achievable bit rate is also limited by card's controller in camera, and the SD card controller in Canon DSLRs is slow, so 6D is not a camera for decent RAW. According to this https://docs.google.com/spreadsheet/ccc?key=0AgQ2MOkAZTFHdFFIcFp1d0R5TzVPTVJXOEVyUndteGc#gid=5 SD card's speed is limited to 40 MB/s in camera. You can use this to determine the resolutions and frame rates you can achieve: http://rbrune.github.io/mlraw/
