abut proprietary floppies, not regular ones. 
There are two things here:

1) software: proprietary format on disk (i.e. not FAT32, NTFS, etc)
2) hardware: proprietary disk format (i.e. quickdisk instead of "standard")

#1 is just a stream of bits, which is what dd excels at.  #2 wouldn't
be any easier on a Windows box, I'm not aware of windows attached
QuickDisk drives for example.

 If it works on Linux, I would be shocked if it
didn't work on Mac,
because underneath macOS on the command line, you have a full Unix
system, very much like Linux other than the kernel, which isn't really
relevant to a floppy drive device. 
I'd hope so... but I believe what Apple puts forward lines up to what they want, and
my feeling is that "dd" is not working or not included. Otherwise that would be
a solution to many problems that have lasted years. Since it hasn't been solved, I
assume dd has been tried and found wanting. But I'm optimistic, but real at the same
time. Let get it tested first.

I think Gordon here (Linux only man) knows the right parameters. I think with all the
Akai, Roland, Emu, Ensoniq, it's all 10 sector stuff instead of 9 sector.

 I look forward to hearing the results.  I could write
the data (I have
a mac and a USB floppy)  but I have no way to verify that it's
right.... 
Why don't you take a S5x floppy, read it using dd, then write it using dd, and see if
your S5x reads it still? That's essentially what I will do when I get back.
