Cómo instalar desde cero OS X El Capitan
One question that many of you are asking is how to go from the OS X El Capitan GM to the final version available on the App Store? Because if you go to the updates inside the App Store nothing will appear. And if you try to download the final version, it will tell you that it’s already installed. Although the GM version number and the App Store version is different.
Well, the method would be to download the version from the App Store, accept it in the box with the Continue button, and then install it as if it were an update from Yosemite to The Captain . A process where you will not lose any data, all your applications will still be installed and nothing will be affected. Not even the much feared performance that worries you so much.
So you know, moving from the GM of OS X The Captain to the final version of the App Store is as easy as downloading and installing as an update. From there you’ll be receiving updates as normal. I hope you find it useful and that it helps to clear up any doubts. Now to enjoy the new system.
If you are registered in the public beta program for OS X you will have to deactivate the option Not to show preliminary updates. This will prevent the Mac App Store from displaying these updates, such as the one that allows you to install the OS X 10.11.1 beta.
To do so, just go to the System Preferences and in the App Store option access the option that allows you to change whether or not you will receive draft versions.
