Were you quick to hop on the test versions of iOS 10 and macOS Sierra? It's time to start updating. Apple has released the second public betas of both platforms, and they're not just adding some spit and polish. The new iOS 10 beta introduces a functioning option for using Touch ID to unlock your device the "old-fashioned" iOS 9 way, where resting your finger is enough to get to your home screen. If you lock an iPhone 6s or 6s Plus, you'll get vibration feedback. And if you're a health maven, you can opt to share your activity and workout data to help improve Apple's fitness features.
The new macOS beta doesn't appear to have as many tangible changes, although it's still recommended if you've been trying the first public release. Whether you're using iOS or macOS, one thing remains true: this is still early software, and you'll want to think carefully before installing either beta if you either can't afford to lose access to certain apps or just don't like grappling with glitches.
