How to Copy an ISO to a USB Drive in Mac OS with dd

Copying an ISO image file to a USB drive in Mac OS X can be done using the dd command in the Terminal. This method is reliable and fast, but it requires some command line knowledge. If you’re comfortable with the command line, follow these steps to copy an ISO to a USB drive:

Step 1: Connect and Identify the USB Drive

Connect the USB drive to your Mac and open the Terminal. Use the command “diskutil list” to view a list of connected drives. Identify the USB volume name and the corresponding disk identifier (e.g., disk3s2).

Step 2: Unmount the Target Drive

To prepare the USB drive for formatting, use the command “sudo umount /dev/(disk identifier)” (e.g., sudo umount /dev/disk3s2).

Step 3: Format and Copy the ISO

Use the command “sudo dd if=/path/image.iso of=/dev/r(disk identifier) bs=1m” (e.g., sudo dd if=~/Desktop/Windows10_x64_EN-US.iso of=/dev/rdisk3s2 bs=1m) to format the USB drive and copy the ISO content to it. Make sure to replace “/path/image.iso” with the path to your ISO file.

Step 4: Complete the Copying Process

Confirm the command syntax and enter your administrator password. The copying process will begin. Please note that there is no progress bar, so you’ll need to wait until the process completes. Once done, you can safely eject the USB drive using the command “diskutil eject /dev/(disk identifier)” (e.g., diskutil eject /dev/disk3s2).

Remember, this method should only be used by experienced Mac users who are comfortable with the command line. Make sure to verify the disk identifier and syntax to avoid data loss. If you’re not confident, it’s best to use Disk Utility or seek alternative methods.
