A short list of instructions
* I use macports - install latest qemu and qemu-utils.
* Download 2024-10-22-raspios-bullseye-armhf.img.xz. Unpack this with Archiver, and mount it as a drive (right click on the newly created .img file). You might need to change your Finder settings to view all drives.
* Create a new directory somewhere (for tidiness) and copy initramfs8, kernel8.img, bcm2710-rpi-3-b.dtb into this new directory.
* To use ssh (I presume you do), In Terminal in the mounted bullseye drive (probably at /Volumes/bootfs), run 'touch ssh'. This creates an empty file which signals to raspios to start the ssh server on first boot.
* Unmount the bootfs drive in Finder, and copy the bullseye image into your new directory with the other files.
* Open a text editor and copy this code to create a file (I called mine rpi.sh). Change permissions to be executable with 'chmod a+x rpi.sh'.

* Run this script!
Notes I can't remember the number of sites I went around picking bits and pieces up to make this work. Thanks to all who went before (shoulders of giants &c.). Importantly, it only works with bullseye. It might work with the 64bit version, but I needed the 32bit armhf. There are other solution on macos for 64 bit Arm operating systems. I use UTM for those, but as of May 2025 it does not support armhf.
