Apple on Tuesday seeded to members of the Apple Developer Program a second beta of iOS 10.2 and a second beta of what would become the third major update to macOS Sierra. iOS 10.2.1 beta 2 (build 14D15) and macOS Sierra 10.12.3 beta 2 (build 16D17a) are now available to install over-the-air via Settings → General → Software Update on iOS devices and under the Mac App Store's Updates tab on the Mac.
The potentially life-saving Emergency SOS feature which debuted on the Apple Watch with the release of watchOS 3 this fall is coming soon to your iPhone via a forthcoming iOS 10.2 software update. As my colleague Cody pointed out, Emergency SOS is now available on an iPhone with iOS 10.2 beta 2. Here's a quick overview of Emergency SOS on the iPhone, how it's invoked and what happens when you use it.
If you're enrolled in the Apple Beta Software Program, you can now download a second beta of iOS 10.2 to your iPhone, iPad or iPod touch. Apple yesterday released iOS 10.2 beta 2 to members of the Apple Developer Program and now the software is available to public beta testers, too. In addition to this new public beta, Apple also seeded macOS Sierra 10.12.2 beta 2 to registered developers today.
Apple on Monday seeded the second beta of iOS 10.2 to developers. Folks enrolled in Apple’s developer program can install the update via the over-the-air mechanism in the Settings app, or from the dev center.
Beta 2 comes one week after the first beta was released, which revealed a number of user-facing changes and improvements like new wallpaper and emoji. Today's beta adds onto that with Apple's new TV app.
