The Mac-specific parts of Photon Transfer (the companion app) are really just the GUI stuff (AppKit) and the GPU shaders (Metal) for the image pipeline. In fact the "MDCUtil" tool should still work on Linux (I haven't tested it in a bit though), and that allows reading imagery from the camera along with lots of other fun debug stuff.

A big part of porting Photon Transfer to Linux would be converting the image pipeline from Metal to... Vulcan (?). The main chunks of that are FFCC illuminant estimation (for white balancing) and LMMSE debayering:

The GUI stuff (list views, image grids, image zooming, oh my) would be a good chunk of work too.
