TL;DR
Apple announced in iOS 27 a new Liquid Glass transparency slider, allowing users to adjust toolbar opacity. This update responds to community feedback after a year of design tweaks. Details on additional macOS changes are still emerging.
Apple has introduced a new slider in iOS 27 that allows users to customize the transparency of Liquid Glass design elements, directly addressing user feedback from the initial implementation. This feature was announced at WWDC 2026 and is now available in beta versions, marking a significant step toward user customization and improved interface clarity.
During the WWDC 2026 keynote, Apple announced that iOS 27 will include a new slider enabling users to adjust the transparency of Liquid Glass elements, such as toolbars and icons. Previously, Liquid Glass was set at a default level of transparency, which some users found too low in contrast, making text and buttons difficult to read. The slider allows users to either increase transparency for a more immersive look or reduce it to make interface elements more visible, with full opacity achievable at the slider’s maximum setting.
Alongside this, Apple confirmed that the default transparency level has been adjusted to be less transparent, improving readability out of the box. The company also showcased updates to app icons, which will now feature layered Liquid Glass effects to add depth, and all app corners will now have uniform rounded edges, regardless of developer updates. These changes aim to unify the visual experience across apps and improve overall interface consistency.
Enhanced User Control Over Liquid Glass Transparency
The addition of a transparency slider in iOS 27 addresses longstanding user complaints about the Liquid Glass aesthetic, which initially lacked customization options. By allowing users to tailor the transparency, Apple enhances accessibility and usability, especially for users who found the original design too translucent. This change demonstrates Apple’s responsiveness to community feedback and a shift toward more personalized device interfaces, potentially influencing future design standards across iOS and macOS.

Evolution of Liquid Glass Design and User Feedback
Apple introduced the Liquid Design aesthetic with iOS 26, emphasizing transparency and depth in interface elements. However, many users reported that the default transparency levels compromised readability, leading to a series of incremental tweaks over the past year. Despite these adjustments, the lack of user control remained a point of contention. The recent announcement at WWDC 2026 signals a move toward greater customization, aligning with broader industry trends favoring user-adjustable UI features.
