How to create a bootable USB stick on OS X

Before you begin, you need to download Ubuntu and, if you want, verify the download.

To run or install Ubuntu on a Mac from a USB stick, the first thing you need to do is insert a USB stick with at least 2GB of free space into your PC.

The easiest way to put Ubuntu onto your stick is to use the UNetbootin USB installer. You’ll need to download and install and follow the instructions.

Download the UNetbootin USB installer.

  1. Download the 64-bit Ubuntu Desktop ISO

  2. Launch UNetbootin and allow the osascript to make changes

    Type your password
  3. Select the ‘Diskimage’ radio button and then click the '...’ button

    unetbootin
  4. Select the Ubuntu ISO file you downloaded and click 'Open'

    Select disk image
  5. Then select your flash drive in the bottom row and click 'OK'

    Tip: If you are unsure which one is your flash drive, in a terminal you can type

    diskutil list

    with the drive not inserted and then inserted to see which one it is.

    unetbootin select drive
  6. After UNetbootin finishes, click ‘Exit’ and restart your Mac

    unetbootin complete
  7. Press alt/option key while the Mac is restarting to choose the USB stick to try or install Ubuntu
