With OS X El Capitan, Apple has built on many of the changes that were brought on by Yosemite. And as with previous OS X versions dating back to OS X 10.7, El Capitan is only available for install via download from the App Store.
So if you previously relied on DVD installs, you won’t be able to do so with this version. Luckily, DiskMaker X helps fill the void by allowing you to make a bootable OS X 10.11 El Capitan USB install drive, making a task such as installing on several different machines easier.
