Mac OS X version and codename
I immediately upgraded my Mac to OS X El Capitan, so I’ll show you how.
Upgrade to OS X El Capitan
When you start it, “OS X El Capitan” is displayed big, so click it. Then the download of El Capitan will start like this. You can check the progress of the download by hovering over the Dock’s Launchpad. After rebooting, the installation of OS X El Capitan will begin.
- It takes about 30 minutes to install OS X. Shazam! It’s El Capitan. This is “OS X El Capitan 10.11”.
