   Apple Opens Public Betas of OS X 10.11 El Capitan and iOS 9

   Josh Centers

   Apple has released [1]public betas of OS X 10.11 El Capitan and iOS 9.
   If you're already enrolled in the public beta program, you can download
   them now. Otherwise, you'll need to sign up. Please, do not install
   these on your main machines! Both are pre-release operating systems
   'many things could be broken, your favorite apps may not work with them
   yet, and you could even lose data due to corruption or crashes. Even
   though you can create a [2]separate disk partition for El Capitan,
   something could still go wrong. Regardless, make sure you have a
   complete backup first!

   To sign up, visit the [3]public beta page and log in with your Apple
   ID. Follow the instructions for OS X or iOS to install the respective
   beta.

   As we wrote in '[4]Snow in Yosemite: Apple Introduces OS X 10.11 El
   Capitan' (8 June 2015), El Capitan brings performance and stability
   improvements, a Windows 7-style Split View mode, a tweaked Mission
   Control, Spotlight enhancements like natural language parsing,
   enhancements to Safari and Mail, a beefed-up Notes app, and more.

   iOS 9 is a huge upgrade for the iPad, adding Slide Over and Picture in
   Picture views, as well as Split View for the iPad Air 2, along with
   other tweaks to make better use of the iPad's larger screen size. iOS 9
   also features a new set of features called Intelligence, which includes
   search suggestions, new Siri commands, and automatic actions based on
   your usage habits. Other changes include the aforementioned Notes
   upgrade, public transit directions in Maps, a redesigned Passbook
   called Wallet, and a new News app that aggregates content from numerous
   sources. Like El Capitan, iOS 9 also boasts a number of performance,
   stability, and energy usage improvements. For details, see '[5]iOS 9 to
   Add More Intelligence and iPad Multitasking' (8 June 2015).
