4. Run the diskutil list command again to determine the device node assigned to USB flash-drive (e.g.
/dev/disk2).
5. Run the diskutil unmountDisk /dev/diskN command (replace N with the disk number from the last
command - in the previous example, N would be 2)
6. Execute sudo dd if=/var/tmp/junos-install-media-usb-srxhe-x86-64-17.4R1-S1.9.img of=/dev/rdiskN
bs=1m
NOTE: Using /dev/rdisk instead of /dev/disk may be faster.
NOTE: If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same
command but replace bs=1m with bs=1M.
NOTE: If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in
use. Start the 'Disk Utility.app' and unmount (don't eject) the USB flash-drive.
7. Run the command diskutil eject /dev/diskN.
