Create a bootable USB drive, for installing Linux, on your Mac.

Picking a Linux distro is like picking your favorite flavor of ice cream.

Convert the .iso file to .img using the convert option of hdiutil

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.

Remove the USB drive from your machine if it’s currently inserted.

Run diskutil list to get the current list of devices.

diskutil list

Insert your flash drive.

Run diskutil list again to determine the device node assigned to your flash media (e.g. /dev/disk1).

diskutil list

insert example output

diskutil unmountDisk /dev/diskN

Replace N with the disk number from the last command; in the previous example, N would be 1.

sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m

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.imgor ./ubuntu.dmg).

diskutil eject /dev/diskN

and remove your flash media when the command completes.


Restart your computer and press alt/option key while the Mac is restarting to choose the USB drive.
