iOS 9 and watchOS 2 will arrive on September 16, and then El Capitan on September 30

Apple will roll out iOS 9 and watchOS 2 publicly on September 16, while the Mac OS X El Capitan will arrive on September 30.

Apple’s iOS 9 is the latest build of the entire iOS lineup, which the company introduced back in June at WWDC along with watchOS 2. It comes with several new features, such as better multitasking skills, ad-blocker in Safari and more.

The Apple Watch’s latest operating system – watchOS 2 – comes with new animated wallpapers, support for third-party apps and more. Facebook Messenger and viewfinder for GoPro products, for example.

And the Mac OS X El Capitan. The desktop OS upgrade includes several minor, yet useful, features under the hood. Apple has improved specific apps – such as Mail, Safari, Notes – along with tweaked multitasking features.

The GM of iOS 9, watchOS 2 and OS X El Capitan are now available for registered Apple developers.
