- Download .iso File
- Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight).
- 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).- 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/option key while the Mac is restarting to choose the USB stick.
