Not for MacBook Pro Retina,
Verified Purchase(What is this?)
This review is from: Lexar Professional Multi-Card Dual Slot USB 3.0 (500 MB/s) Memory Card Reader - Black (Personal Computers)
I inserted the card and connected the reader to my MBPr. The computer did not detect the card. Once I inserted the card back into my camera, the data on it was corrupted and I lost all my pictures. Avoid this device if you have a MacBook Pro Retina. I am returning it and requesting a refund.
