Since Aperture has stopped development, I have sought an open source alternative for my workflow. I am interested in Dark Table, but I can't navigate to my second internal HD. The file picker doesn't let me go higher than root on my OS drive. I am using OS X 10.10.3 on 2015 15" MBP and have a second internal HD installed using Optibay. How can I load my images into Darktable from the second internal HD?
