Just in case you wanted to add it, you can also create a bootable flash drive using the dd command in OS X's terminal
Convert the .iso file to .img using the convert option of hdiutil (e.g.,
hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso)
Note: OS X tends to put the .dmg ending on the output file automatically.
Run
diskutil list to get the current list of devices
Insert your flash media
Run
diskutil list again and determine the device node assigned to your flash media (e.g. /dev/disk2)
Run
diskutil unmountDisk /dev/diskN (replace N with the disk number from the last command; in the previous example, N would be 2)
Execute
sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg). <
You can easily specify the file path in terminal by simply dragging the file into the shell
Using /dev/rdisk instead of /dev/disk may be faster.
If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.
If you see the error dd:/dev/diskN: Resource busy, make sure the disk is not in use. Start the 'Disk Utility.app' and unmount (don't eject) the drive.
Run diskutil eject /dev/diskN and remove your flash media when the command completes
Restart your Mac and press alt while the Mac is restarting to choose the USB-Stick
(Pulled from the 'Get UNE' page from Ubuntu.com looks somewhat daunting, but nice and easy if you can just follow some simple instructions :] )
(Also this may take a while! If you run the last command 'dd if= / of' and get a blinking cursor on the next line, leave it, that means its doing it's job, you'll know its finished when the shell tells you how much data went in and out)
OP - Apologies if this post is a bit messy, feel free to disregard if you feel this is unnecessary.
