OS X Yosemite is a free download that comes to your Mac from the Mac App Store in the form of an installer that starts up automatically.

What if you want to perform a clean install, completely erasing your startup drive? Or perhaps you’d like to have the installer on a bootable USB drive, so you don’t have to keep downloading it every time you wish to upgrade one of your Macs?
