Apple seedsthird developer betas for iOS 26, iPadOS 26, macOS 26
Apple is now on its third developer beta round for iOS 26, iPadOS 26, macOS 26, watchOS 26, and visionOS 26.
The main visible one is the introduction of Liquid Glass, a new UI aesthetic that uses transparency throughout the operating systems and Apple's first-party apps. AppleInsider and Apple strongly advise against users installing test operating systems or beta software onto primary or "mission-critical" hardware. Ideally, beta participants should use secondary or non-essential hardware and ensure they have sufficient backups of their critical data at all times.
