Yesterday, Apple seeded Developer Betas for iOS 10.1, macOS 10.12.1 Sierra, watchOS 3.1, and tvOS 10.0.1. Today, the applicable Public Beta builds have been released, which are iOS and macOS.
The main notable new feature in iOS 10.1 is Portrait Mode for the iPhone 7 Plus. This allows the camera to focus on a subject and blur the background, creating an effect known as bokeh.
macOS 10.12.1 Sierra will create a Portraits folder in the Photos app to support the new feature in iOS, but that's about it. The rest of the changes focus on under-the-hood improvements.
The news comes nine days after Apple released iOS 10 into the wild, and just two days after launching macOS 10.12 Sierra. The company called iOS 10 its biggest iOS update ever, adding features such as a new lockscreen experience, extensions in Messages and Maps, all-new designs in the News and Music apps, and more.
macOS Sierra's most notable new feature is Siri, but it also includes some of the features that came in iOS 10, such as grouping photos by people, places, and things.
To sign up for Apple's Public Beta program, head over here. If you're already on it, you can get the latest build of iOS or macOS by going to Settings -> General -> Software Update on your iOS device, or go to the Updates tab in the Mac App Store.
