Bootable floppy in Mac

How can I make a virtual floppy image and copy my bootloader in the first sector in Mac?

dd, perhaps.

What's dd?

DD is not available for Mac. The only thing I want to do is make a bootable floppy image or a bootable disk image. Not even that, I just want to test my bootloader.

Edit: Sorry I found out that I do have dd

You should create an empty file with the exact size of sectors that your real floppy would have, i.e. the file size should be:

sectors_on_disk * sectorsize

then you copy you 512 byte-boot sector right at the start of this file and then you can use this file as a virtual floppy

with dd you can do just that
