Does anyone know of a way to copy a bootable SD card on a Mac? I've tried Balena Etcher, the Raspberry Pi Imager and Apple Pie Baker. I copy from a known-good SD card to a file, but when I copy back to a new SD card, the resulting image won't boot on a Pi. It takes an hour for me to rebuild Direwolf/Direwatch from scratch, so I'd really like to? be able to burn completed images to a new card.
