Apple Beta Software Program

OverviewBETA
Help make the next releases of iOS 10 and macOS Sierra our best yet. As a member of the Apple Beta Software Program, you can take part in shaping Apple software by test-driving pre-release versions and letting us know what you think.
As a member of the Apple Beta Software Program, you’ll be able to enroll your Mac or iOS device to access the macOS and iOS public betas. Each public beta comes with a built-in Feedback Assistant app that appears in your Dock on your Mac and on the second page of your Home screen on your iOS device. When you come across an issue that needs addressing, send your report directly to Apple with Feedback Assistant.
