In this guide I will teach you how to create a bootable Ubuntu USB on macOS with Unetbootin. Since Unetbootin is also available for Windows and Linux, this tutorial can be use on those operating system as well with minor differences.
Ubuntu Linux is one of the most user friendly Linux distribution in the market. I remember back in 2001 the Linux installation process was cumbersome and only for advance computer users. Linux came a long way and now we can enjoy the user friendliness Ubuntu Linux offers to both beginner and advance users.
A minimum of 4 GB USB Flash disk size is required to continue with this tutorial.

Verify that we downloaded both Ubuntu image and Unetbootin software.
Open Unetbootin and copy it into Application folder
Confirm Unetbootin launch. This only happens once.
Enter your password to allow unetbootin access to filesystem and USB
Inside Unetbootin, select the Ubuntu image file we downloaded earlier.
Load the Ubuntu image file.
Now we are ready to start creating the bootable USB. Press Ok button to start.
Allow Unetbootin access to USB or external volume. Please remove other USB flash drive to avoid accidental deletion of data.
Unetbootin will take minutes to complete. You may have some coffee or tea during this time.

Turn off the computer and plug-in our bootable USB flash drive.
Turn on the computer and press function key to display boot selection page.
Boot selection page. Select the bootable flash drive we created.
