I've spent some time attempting to make a Cocoa that lets you burn an Ubuntu ISO to a USB memory stick on OS X.

I think I've got as far as I'm gonna get with it now, sadly.


How far I got...

  • The UI is pretty concise
  • A USB stick gets detected when plugged in
  • The right signal is sent to the dd process and parses the progress for the progress bar
Major outstanding issues

  • It's really SLOW. I'm not familiar with how the dd command line utility works -- people keep talking about 'eraseblocks' and suchlike and my eyes glaze over..
  • It doesn't detect and inform the user when the write is complete
  • It doesn't seem to create a bootable device
  • I can't see how to automatically remount a device after I've unmounted it with diskutil
  • I'm not amazingly confident that once I've detected the device a volume resides on I'm not then going to end up destroying all the data on the wrong drive 
The project is on Launchpad here: https://code.launchpad.net/~michaelforrest/ubuntuusbcreator-osx/trunk

It would be pretty awesome if you were able to help out.
