FSKit .mcraw (from Motioncam) File System for MacOS 26 (mcrawfs)

An implementation of a file system driver for mounting .mcraw files using FSKit and MacOS 26’s brand new FSPathURLResource API.

This project lets you mount .mcraw files from Motioncam as file systems on MacOS 26 and explore their contents natively.

It exposes the individual .dng frames as frames.
