Apple unveiled iOS 9 and OS X El Capitan during WWDC 2015 last week. One major focus of these upcoming releases of operating systems is performance and battery life enhancement. Apple highlighted during its developer conference that iOS 9 and OS X El Capitan will run faster and smoother compare with iOS 8 and OS X Yosemite.
iOS 9 is compatible with all devices that can run iOS 8. Similarly OS X El Capitan runs on all Macs that are capable of running OS X Yosemite.
iOS 9 supported devices are iPhone 4s, iPhone 5, iPhone 5c, iPhone 5s, iPhone 6, iPhone 6 Plus, iPod touch 5th generation, iPad 2, iPad 3rd gen, iPad 4th gen, iPad Air, iPad Air 2, iPad mini, iPad mini 2 and iPad mini 3. Similar to past iOS releases, not all new iOS 9 features are available for all supported devices. One of the more exciting new multi-tasking split-screen picture-in-picture feature is limited to iPad Air 2 or newer, likely due to the processing power required.
Apple is giving developers the option to support 64 bit only devices in iOS 9. When an app or game enables this option, user with a non-64 bit devices will not see the app in the App Store. The list of 64-bit iOS devices are iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air and iPad Air 2. It is expected that games that can not run well on older hardware will choose to cut off support by going 64-bit only.
The minimum Mac requires to run OS X El Capitan is the same as OS X Yosemite:
- iMac (Mid-2007 or newer)
- MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or newer)
- MacBook Pro (13-inch, Mid-2009 or newer), (15-inch, Mid / Late 2007 or newer), (17-inch, Late 2007 or newer)
- MacBook Air (Late 2008 or newer)
- Mac Mini (Early 2009 or newer)
- Mac Pro (Early 2008 or newer)
- Xserve (Early 2009)
Apple is claiming in its testing that OS X El Capitan will have better performance on the same Mac when compared to prior version of OS X, with up to 1.4x faster app launch, up to 2x faster app switching, up to 2x faster of displaying of first Mail messages, and up to 4x faster opening PDF in Preview.
Both iOS 9 and OS X El Capitan will have a public beta coming soon and a release scheduled this fall.
