Creating a Bootable Kali USB Drive on OS X
OS X is based on UNIX, so creating a bootable Kali Linux USB drive in an OS X environment is similar to doing it on Linux. Once you’ve downloaded and verified your chosen Kali ISO file, you use dd to copy it over to your USB stick.
WARNING: Although the process of imaging Kali on a USB drive is very easy, you can just as easily overwrite a disk drive you didn’t intend to with dd if you do not understand what you are doing, or if you specify an incorrect output path. Double-check what you’re doing before you do it, it’ll be too late afterwards.
Consider yourself warned.
  1. Without the USB drive plugged into the system, open a Terminal window, and type the command diskutil list at the command prompt.
  2. You will get a list of the device paths (looking like /dev/disk0/dev/disk1, etc.) of the disks mounted on your system, along with information on the partitions on each of the disks.

  3. Plug in your USB device to your Apple computer’s USB port and run the command diskutil list a second time. Your USB drive’s path will most likely be the last one. In any case, it will be one which wasn’t present before. In this example, you can see that there is now a /dev/disk6 which wasn’t previously present.

  4. Unmount the drive (assuming, for this example, the USB stick is /dev/disk6 — do not simply copy this, verify the correct path on your own system!):
diskutil unmount /dev/disk6
  1. Proceed to (carefully!) image the Kali ISO file on the USB device. The following command assumes that your USB drive is on the path /dev/disk6, and you’re in the same directory with your Kali Linux ISO, which is named “kali-linux-1.0.9a-amd64.iso”:
sudo dd if=kali-linux-1.0.9a-amd64.iso of=/dev/disk6 bs=1m
Note: Increasing the blocksize (bs) will speed up the write progress, but will also increase the chances of creating a bad USB stick. Using the given value on OS X has produced reliable images consistently.
Imaging the USB drive can take a good amount of time, over half an hour is not unusual, as the sample output below shows. Be patient!
The dd command provides no feedback until it’s completed, but if your drive has an access indicator, you’ll probably see it flickering from time to time. The time to dd the image across will depend on the speed of the system used, USB drive itself, and USB port it’s inserted into. Once dd has finished imaging the drive, it will output something that looks like this:
2911+1 records in
2911+1 records out
3053371392 bytes transferred in 2151.132182 secs (1419425 bytes/sec)
And that’s it! You can now boot into a Kali Live / Installer environment using the USB device.
To boot from an alternate drive on an OS X system, bring up the boot menu by pressing the Option key immediately after powering on the device and select the drive you want to use.
