Like the original author says, finding information on how to get (or ‘burn’) an ISO file onto a USB stick on the Mac is a lot harder than it seems. Here are the basic steps (culled from the excellent and exhaustive instructions here):
- Use Disk Utility to wipe the USB disk — a single partition formatted as free space.
- Convert the ISO file to IMG with
hdiutil convert -format UDRW -o some_filename.img some_filename.iso
- Identify your USB with
diskutil list
- Replace
/dev/diskX
with/dev/rdiskX
and finish the job withdd if=./some_filename.img.dmg of=/dev/rdisk1 bs=1m
