Let’s start with iOS 10.3. The new version adds Find my AirPods and we already covered what you can expect from the new feature. You can see them on a map if they’re connected to an iOS device or you can play an alarm if you have an AirPod hidden below a stack of magazines. And if they’re not around, you can see the last location when your phone was connected to your AirPods.
With iOS 10.3, Apple is rethinking ratings in the App Store with native review prompts and the ability to reply for developers. iOS 10.3 also adds a couple of new Siri features, such as cricket sports scores. There are also various improvements, such as a thread view in Mail and dynamic app icons. More at 9To5Mac.
Some good updates here. Sadly my iMac is too old for Night Shift- not sure what else is limited to newer Macs, but will explore.
