On macOS, the instructions are to
# lzma -d nomadbsd-x.y.z.img.lzma
# dd if=nomadbsd-x.y.z.img of=/dev/rdiskX bs=1m
Hint 1: when writing to /dev/*, you need super-user rights, so you will need to
# sudo dd if=nomadbsd-x.y.z.img of=/dev/rdiskX bs=1m
Edit: I have been informed the
# in front of the command means “super-user prompt”, so I removed this hint.
If, like me, you have BSD CoreUtils installed (via HomeBrew, for example), the block size (bs) of 1m is invalid. You will need to use a capital M, so
If you have aggressive power savings settings, you might want to keep the computer awake during the process;
# caffeinate lzma -d nomadbsd-x.y.z.img.lzma
# caffeinate dd if=nomadbsd-x.y.z.img of=/dev/rdiskX bs=1m
Final thought; As I haven’t tested this it is not a hint, but a thought;
You probably could use BalenaEtcher to write the .img to the USB drive.
