Hello all, I am new to Mac. I got the new rMBP 2015 15". I am trying to download images from my CF card which is connected via a card reader. The card is normally recognised and when I am trying to download images, the process does't start and I always get an error message "Disk not ejected properly". Then everything restarts again...mac will connect the CF card via the reader and will do the same thing again - disconnect when I am trying to download images. No idea why this is happening. I have connected the same card to my PC via the same card reader and it is working OK. What is the issue? Thanks!
