Nikon released Capture NX-D v.1.0.1 update only for Windows users (the latest version for Mac is still 1.0.0). Here are the download links:
The new version contains only one fix:
When the 64-bit Windows version of the application was used to create JPEG-format files converted from RAW (.NEF/.NRW), TIFF, or JPEG images using the Convert Files... or Run Batch Process... option in the File menu, a gray band was sometimes visible at the bottom of the images when they were opened in the 64-bit Windows version of Capture NX-D. This issue has been resolved.
