The Problem: on OS X Yosemite (10.10.3), starting Lightroom 2015 (LR6?) after the SD card from my camera has been inserted into the MacBook Pro's SD slot, and going for import shows the card to be empty. If I navigate into the card's picture folder the pictures are there.
After ejecting the card and inserting it again the pictures show on the import dialog.
Not a deal breaker, but annoying nevertheless. Anyone with the same problem and possibly a solution?
