Overview

  • Apple has released the seventh developer betas for iOS 26, iPadOS 26, macOS Tahoe 26, watchOS 26, tvOS 26, and visionOS 26, accelerating weekly builds focused on stability and the Liquid Glass redesign.
  • The fourth public betas of iOS 26, iPadOS 26, macOS 26, tvOS 26, and HomePod 26 arrived shortly after developer releases under Apple’s expedited public beta cadence.
  • iOS 26 beta 7 adds an Adaptive Power Notifications toggle under Settings > Battery, enabling users to receive alerts when the system activates power-saving performance adjustments.
  • Beta 7 reintroduces the redesigned blood-oxygen measurement feature for supported Apple Watch models in the U.S. following Apple’s regulatory and patent-litigation workaround.
  • Apple and publishers remind testers to back up devices and install betas on secondary hardware as iOS 26 drops support for A12-and-earlier devices and some AI features remain hardware-gated.
