I'm following the official instructions for burning an Ubuntu image on a USB stick from a macbook pro.
Step 8 when trying
$ sudo dd if=/path/to/downloaded.img of=/dev/rdisk1 bs=1m
I'm getting (after having typed my root password)
dd: /dev/rdisk1: Permission denied
Why is this happening?
I had that same thing happen to me. There was a write-protect switch on the flash drive I was using. Once I switched it to enable writing onto the disk, it worked.
