3 Connect the USB cable from your keyboard and mouse.
Your Mac mini does not come with a keyboard and mouse, but you can use almost
any USB keyboard or mouse with your computer. If your keyboard has a USB port,
you can plug your mouse in to the USB port on the keyboard. If it doesn’t, you can
plug the mouse in to a USB port on the back of the computer.
