How to Create a Clonezilla USB stick on Mac OS

Without using any additional software then what’s already on your Mac, you can easily create a USB stick that boots to Clonezilla. Just follow the below instructions and you’ll be well on your way to cloning disks and partitions.

First you have to actually download the Clonezilla ISO. If you’ve already done this you can skip this step.

Download Clonezilla

Next we need to convert the ISO image to a DMG

To do this you’ll need to open up Terminal which you can find in either Applications -> Utilities or by pressing Command + Space to launch spotlight and typing Terminal

In the Terminal window you’ll need to type the following: (assuming that the clonezilla image is in your downloads folder)

[simterm]
hdiutil convert -format UDRW -o clonezilla clonezilla-live-20190124-eoan-amd64.iso
[/simterm]

Next, issue the following command and make a note of the output.

[simterm]
diskutil list
[/simterm]

In the output you’ll notice that there are several disks such as /dev/disk0, /dev/disk1, /dev/disk2, etc…

Plug in your USB stick and issue the command again

[simterm]
diskutil list
[/simterm]

You should now see a new disk, for me this is /dev/disk5

We will need to unmount this disk so that we can perform the necessary operations on it.

[simterm]
diskutil unmountDisk /dev/disk5
[/simterm]

With the disk unmounted, we can now write the contents of the DMG image that we created from the Clonezilla ISO

[simterm]
sudo dd if=clonezilla.dmg of=/dev/rdisk5 bs=1m
[/simterm]

Once this finishes we’ll need to unmount the USB stick

[simterm]
diskutil unmountDisk /dev/disk5
[/simterm]

You should now have a working Clonezilla USB stick, congratulations 🙂
