I was trying to create bootable USB of Ubuntu 17.04. First, I erased everything from the pen drive and then started to copy using
sudo dd if=path_to_ubuntu_image of=/dev/rdisk2 but it is taking around 5 hrs to complete the process. I read previous answers about speeding up it using
rdisk instead of
disk but I was initially using that only. There was to use
bs but I have doubt will it bring some change in the bootable image while copying ? Please help.
Size of Ubuntu - 1.63GB
I am using the latest version of macOS High Sierra.
