Tried RawWrite with some Mac disk images and RawWrite is picky with disk images too.
It is possible to write Mac floppy images to a physical floppy, but the image must
be of raw nature.
This had to be expected.
Hence the name RawWrite.
Creating a raw (floppy disk) image is not too hard from Terminal in macOS, but you may use this one for a trial:https://www.magentacloud.de/lnk/L54sJsh5
As you want to place some files onto the raw disk image named 1440.dsk, best use MiniVMac.
The MiniVMac version does not matter much.
Run MiniVMac and boot with an OS of your choice.
(If you are missing a bootable volume, you may use this:http://macintoshgarden.org/apps/macos-753-emulators
When MiniVmac has finished booting, drag the 1440.dsk onto the MiniVMac screen.
The raw image mounts as Untitled volume. You will notice two test apps, which you may delete.
Copy the needed files to the Untitled volume, rename the volume if you want to.
Shutdown the Mac System and close MiniVMac.
If needed, take the 1440.dsk to your Windows PC.
Insert a PC formatted floppy into the PC floppy drive.
Run RawWrite 0.7 and navigate to the place where your 1440.dsk resides.
Set the opening requester to "all files" to make the 1440.dsk file visible.
Write image to floppy drive.
This way you may write 1.4 MB Macintosh floppies from Widows 10 64bit or lower.
You do need a stock "HD" 3.5" floppy drive, internal or USB obviously.
It is not possible to write 800k or 400k floppies for Macintosh that way.
