Can someone try this out on their machine please and let me know if it doesn't work for them either.

Steps to reproduce
  • Open Disk Utility
  • Drag an ISO image into the left sidebar
  • Insert an USB Stick with enough space to contain the image
  • Go to any restore tab in Disk Utility
  • Drag the ISO file to the source
  • Drag the Volume from the USB drive to the destination
  • Check erase destination
  • Hit restore

Results for me are (in any number of varieties to do this) either "Invalid argument" or in the log "Could not validate source - error 254".

This worked fine in Mac OS 10.6.4.
 
I have actually found out that this bug has been around for many people for a while. Seems the last version of Mac OS that reliably supported this was 10.5.x...
