Apple is now seeding public beta 2 of iOS 10 and macOS Sierra operating systems. All compatible Macs, iPhones and iPads can install those firmwares. The iOS 10 public beta 2 is seeding as a 311MB OTA update, and anyone that has applied for the Apple's open beta program can install it. The same goes for macOS Sierra - it's already available in the App Store. The devs got developer beta 3 for iOS 10 and macOS Sierra earlier this week, too. The final versions of those will kick off this fall.
