I am using a MacBook macOS Mojave 10.14.5. I can list the device with
diskutil list, but it isn't mounted. I perform the
dd command below. The output states
input/output error, which doesn't give a lot of information.
sudo dd if=~/Downloads/ubuntu-18.04.2-desktop-amd64.dmg of=/dev/rdisk2s2 Password: dd: /dev/rdisk2s2: Input/output error 1+0 records in 0+0 records out 0 bytes transferred in 80.936791 secs (0 bytes/sec)
Anyone know how I can resolve this issue?
