Coming to all in fall — Apple says the developer betas for the new iOS, WatchOS, and MacOS Big Sur will all be available to developers today. Public betas will follow in July.
"New public betas for iOS 14, iPadOS 14, macOS Big Sur, tvOS 14 and watchOS 7 are coming soon," Apple says on the beta program website. "As a member of the Apple Beta Software Program, you can help shape Apple software by test-driving pre-release versions and letting us know what you think. If you’re not already a member, sign up today." If you sign up, once the beta is available you'll be able to install it on your device and offer feedback to Apple using the company's Feedback Assistant app.
For years, Apple has released its new iOS to all devices that support it in September when it unveils its new iPhones. So, if you're gun shy, or don't have another device to test it on, you won't have to wait too long before you can get some of the new features, like widgets, the new App library, and the impressive translate app. Alternatively, if you're happy to take the plunge but don't want to sign up for a developer account, you an wait until next month when the public beta releases.
