Lexar 600x cannot be read by MacBook Pro 15
May 17, 2012

I bought a Lexar Professional 32gb USH-1 600x speed SDHC memory card for my Olympus OM-D camera. It works fine in the camera. However, I cannot read the card int my year old MacBook Pro 15 built-in card reader. I spent a lot of time talking to a Lexar rep who offered no solution. I then tried it with a new Promaster usb card reader and it worked fine.

I then bought the SanDisk equivalent card (32gb, SDNC Extreme Pro UHS-1 95x) and it works fine in the MacBook Pro.

Has anyone else had this problem. Any ideas on how to solve it? I do not want to have to use a usb card reader in the field.
