Which are now accessible to all
As he announced last month during his WWDC (Worldwide Developers Conference) dedicated to developers, Apple has made available in public beta the new iteration of its mobile operating system, iOS 9, as well as its operating system Mac OS X El Captain.
9 beta of iOS will allow testers to get an overview of upcoming features in the operating system with new applications as well as applications that have been improved. Same story on the side of El Captain who sailed many enhancements of its flagship applications, whether Safari, Spotlight, Mail, Maps or even photos. Note also features multitasking thanks to split screen (Split View), fast access to an application via the right edge (Slide Over) or displaying a video image mode in the image.
So far, beta wasnt reserved only for developers, which implies more or less three things: it was designed for people wanting to ensure the compatibility of their applications, it was less stable than that broadcast now, you had to go through a developer account to access it. With this beta, simply register for the "beta software program from Apple" if you have a device that meets the criteria.
Thus, you can register your iOS device or Mac OS so that they access the public beta versions of iOS and X and their future updates. Each has a public beta app integrated devaluation Wizard that appears in the Dock of your Mac and on the second page of Home screen of your iOS device.
Remember that even if this public beta, these versions are still in beta, so still likely to be unstable. It is recommended to backup your iDevice before starting the installation of the Beta. You should also avoid installing the beta of iOS 9 on a device to be fully operational.
If Cupertino is not new to the beta release of iOS (the company had attempted the coup in March with iOS 8.3), this is the first major public beta, the first involving new features and others most significant advancements (unlike minor beta embarking advancements as fixing bugs for example).
Apple did not release the maximum number of participants.
