Always when I need to make a bootable usb drive on a mac I struggle, I end up switching to windows because none of the below works for me, I'm using MacBook Pro:

  • running sudo dd of=/dev/rdisk2 bs=512k in terminal
  • using Disk Utility, formatting the usb to have 1 partition, MBR and unmounting the partition, then dragging the iso image onto restore tab
  • using diskutils for the above

On Windows we have plenty of tools. I always struggle with creating either Ubuntu bootable usb stick or Windows 7 in the company deployment process.

a) You can use the free and open source Mac Linux USB Loader app to make a bootable USB drive.


b) Follow the instructions for How to create a bootable USB stick on OS X (it has a step to convert ISO files to IMG before writing it to the USB drive).
