You did not respond to my question/issue. I do not use the NX2 software --- I use Aperature on my Apple. NX2 is a Nikon based software - two different things.
The images can be pulled to Aperature -- but not downloaded into the program ----The conflict is between the NIKON D7100 and Aperature.
OK --- I downlaoded the Nikon software --- went to Aperature and nothing happened. Is there a setting in the Nikon Software that I need to make?
OK --- it worked. When I pull up Aperature and try to download from the D7100, the NK2 program is opened and pulls them into Aperature. After I complete the download, the Nikon software disaappears and the photos are on Aperature as per normal.
