Apple has released the third developer betas for its iOS 26, iPadOS 26, macOS Tahoe 26, watchOS 26, tvOS 26, and visionOS 26 operating systems. These updates follow the second round of betas issued in late June 2025, continuing the testing cycle that began at WWDC 2025. A key change in iOS 26 beta 3 is the reduction in the transparency of the "Liquid Glass" user interface design, which was initially criticized for causing visibility and readability issues. The update modifies the UI elements to be less translucent, adopting a frosted glass appearance to enhance usability. This adjustment aims to address developer and user feedback on the earlier beta's excessive glassiness. Alongside iOS 26, Apple has also advanced the testing of its current-generation software with the third betas of iOS 18.6, iPadOS 18.6, macOS Sequoia 15.6, watchOS 11.6, tvOS 18.6, and visionOS 2.6. The company continues to refine features and fix bugs across its platforms as it prepares for public beta releases.
