Putting this here for safe keeping because the original article was deleted, and I don’t do this often enough to remember it always:
- Open the Terminal Application.
- Type command to convert the .iso file to .img using the convert option.
1hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso
- Insert your flash media.
- Type command to determine the device node assigned to your flash media (e.g. /dev/disk2).
- Type command to unmount the flash (replace N with the disk number from the last command; in the previous example, N would be 2).
1diskutil unmountDisk /dev/diskN
- Type DD command (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img). Prepend the device path with “r” for the raw path which is much faster than without the “r”.
1sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m
Note: your file might also be called
downloaded.img.dmg. That’s okay.
- Type command to eject the flash drive.
1diskutil eject /dev/diskN
- Restart your Mac and press alt/option key while the Mac is restarting to choose the USB stick as the boot disk.
