LibRaw Monochrome2DNG 1.7.0.72 macOS

It takes input files from cameras that have been converted to monochrome.
It then saves it as "truly" monochrome DNG files, suitable for using with popular converters that support the DNG format (that is to say, almost all of them).
With this:
One can turn on automatic "monochrome" recognition and convert only the files from converted cameras (so one can process a large archive that has both color and monochrome files in it quickly, in one pass).
Automatic mosaic pattern suppression is supported (output files will not have 1-pixel grid patterns)
Several formats for output DNG are supported, which allows one to use their RAW converter optimally.
Filter input files by Vendor/Model/Camera serial to process large archives faster.
System Requirements
Intel-based Mac.
Processor with 64-bit support (that's every Intel Mac, excluding models from 2005-2006, that use Intel Core Solo and Intel Core Duo processors).
(Mac OSX) 10.6 or later.
We recommend a video card with OpenGL 2.1 support (that's every native Mac video card, that works with OS X 10.6).
An OpenGL emulator will be used if such a video card is not present in the system; some of the advanced features of FastRawViewer will take significant time to render.
