I select to install Mac OS X El Capitan to the internal SSD. I boot the USB stick using the Option key and go to Disk Utility and format the internal SSD in the MacBook, which I then verify that it is empty in the end. I created the USB stick using this command: sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia -volume /Volumes/Untitled -applicationpath /Applications/Install OS X El Capitan.app –-nointeraction I boot the USB stick I made from an El Capitan package that I downloaded from the App Store. Bizarre! Somehow during the install of El Capitan it decides to switch and install Yosemite instead of El Capitan. When I boot the USB to the El Capitan installation, everything goes through, but for some reason I end up with Yosemite instead of El Capitan.

I made a bootable USB drive with the El Capitan installationfor my 2013 13" MacBook Air.
