Mac – Burn an ISO to USB

Extract from http://forums.macrumors.com/showthread.php?t=598291

– Insert USB Stick

– Open Disk Utility, Click ERASE. Format USB using MS-DOS (FAT)

– When Disk appears in Left hand column, right click and get Information (note down the “Disk Identifier : eg disk6”)

– Then right click the Disk and select Unmount. (the drive still shows but the disk unmounts)

– Switching to the Terminal App

– Change to superuser / root, by issuing:

sudo su – (then enter your password)

– Change directory to where ever your recently downloaded .iso image is stored, eg: Downloads – My file iso is called ubuntu-11.04-server-amd64.iso, (approx 650mb) so use the following command:

dd if=ubuntu-11.04-server-amd64.iso of=/dev/disk6 bs=8192

– This will start copying the file to the USB stick. There is no “verbose” or screen “output” of what is happening. But after 15mins you should see something like:

Mac-Pro: Downloads root# dd if=ubuntu-11.04-server-amd64.iso of=/dev/disk6 bs=8192 86222+0 records in 86222+0 records out 706330624 bytes transferred in 461.654162 secs (1529999 bytes/sec)
