This article will explain how a Linux USB stick can be created from a Mac environment, from which Linux can be started without installation.
But even if you have made the decision to install Linux individually or next to Windows or OSX, a bootable Linux USB stick is the most practical and quick solution. It is therefore not necessary to perform a complete installation to use or try out Linux. One of the many powerful features of Linux is the ability to start a distribution directly from a USB stick, without affecting your hard drive and the operating system on it.
