The last time I did it, I had downloaded a new Mac OS X El Capitan installation package from Apple and once again formatted and recreated the USB stick, and still the same bizarre thing happened. I repeated this process 3 times today just to verify I wasn't going crazy or missing something, and it went exactly as I described. Whatever happened to El Capitan I started installing just minutes ago?Īfter I create my account and load the desktop, I confirm that it is indeed running Yosemite even though I had started the El Capitan installation. When it starts up again, the first screens load with the Terms and Conditions and says Mac OS X Yosemite.

Then it takes about another 15 to 20 mins, and then reboots one more time. It just has a the Mac OS X logo (the big X logo inside the circle). However, this time the screen does not say El Capitan as it did before.

Again, I am verifying it is in fact installing to the internal SSD, and the screen says "El Capitan" on the screen through the install process.Īfter 15 mins or so, the MacBook reboots and then automatically starts installing MacOS X again, all automatically, just a progress bar and the Mac OS X logo on the screen. 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.
