Apple has released the fourth iOS 12 public beta for iPhone and iPad. The new version follows iOS 12 developer beta 5 which was released yesterday. The new version includes minimal changes including new tones within FaceTime, updates to the Stocks widget, and more. tvOS 12 public beta 4 and macOS Mojave public beta 4 are also available today.

Apple’s public beta program allows users who are not registered developers to test pre-release versions of iOS, tvOS, and macOS with new features for free (and a few bugs). Apple’s developer program also includes watchOS betas for Apple Watch but costs $99/year. Enroll in the iOS 12/macOS Mojave/tvOS 12 public beta for free here: beta.apple.com.
