  1. better raw write (pls note rdisk3 instead of disk3)
    sudo dd if=./debian-9.1.0-amd64-DVD-1.iso of=/dev/rdisk3 bs=1m
    sudo dd if=./debian-9.1.0-amd64-DVD-1.iso of=/dev/disk3 bs=1m

  2. Step 9 should be disk3 instead of disk1
    I’m stuck at step 8 where it says dd: /dev/disk2: Resource busy
