Lead
Bloomberg reporter Mark Gurman said in his March 15, 2026 Power On newsletter that Apple’s internal builds of iOS 27 and macOS 27 show no sweeping redesign of the company’s Liquid Glass visual language. The report comes as Apple prepares to unveil its next generation of operating systems—iOS 27, macOS 27 and watchOS 27—this year, with an emphasis on performance and stability. Although Liquid Glass has drawn mixed feedback over readability, Apple has introduced incremental customization in iOS 26 updates. Gurman advises users to expect gradual tweaks rather than an immediate overhaul.
Key Takeaways
- Bloomberg’s Power On (March 15, 2026) reports that current internal builds of iOS 27 and macOS 27 do not include major Liquid Glass redesigns.
- Apple is expected to focus iOS 27 on performance and stability across platforms including macOS 27 and watchOS 27.
- Design lead Alan Dye departed Apple late last year to join Meta; Steve Lemay is the new design lead overseeing interface work.
- Since Liquid Glass’s debut in iOS 26, Apple added a ‘Tinted’ option in iOS 26.1 and a setting to disable Liquid Glass highlights in iOS 26.4.
- Engineers prototyped a systemwide slider during iOS 26 development that worked for the lock-screen clock but faced challenges when extending across apps, folders and navigation bars.
- Gurman characterizes Liquid Glass’s future as incremental: expect years of refinements rather than a rapid redesign.
Background
Apple introduced Liquid Glass as a prominent visual element in iOS 26, aiming to refresh system chrome and layering. The new look prioritized translucency and motion, a departure from the flatter, more utilitarian palettes of previous iterations. Responses were mixed: some users praised the aesthetic, while others raised concerns about contrast and legibility in certain contexts. Accessibility advocates and design critics pressed for options to improve readability without sacrificing the refreshed visual identity.
The company has already moved incrementally: early point updates to iOS 26 brought user-facing toggles and modes to adjust the effect. Internally, the design organization also saw change when Alan Dye, the design lead associated with Liquid Glass, left Apple in late 2025 to join Meta; Steve Lemay subsequently assumed design leadership. At the same time, Apple’s engineering teams signaled a broader priority shift toward stability and performance for the 2026 OS wave, tempering expectations for dramatic visual reworks.
Main Event
Gurman’s reporting indicates that internal snapshots of iOS 27 and macOS 27 retain the Liquid Glass system in much the same form as shipped in iOS 26, with only modest refinements visible. The newsletter notes that Apple’s internal builds do not reflect major aesthetic departures, suggesting that the company has chosen an evolutionary path over a disruptive redesign. Engineers and designers appear to be concentrating on smoothing edge cases and improving the underlying rendering rather than swapping in an entirely new visual system.
One tangible area of development is a proposed systemwide slider to control the intensity of the glass effect. Apple successfully implemented a fine-grain control for the lock-screen clock during iOS 26 development but found engineering hurdles when attempting to extend that control consistently across folders, home screen elements and navigation bars. If those cross-system issues are resolved, a broader slider could surface in iOS 27; if not, Apple will likely keep adjustments limited to targeted components.
The product team’s apparent decision to stagger changes reflects the design and engineering cost of a system-wide visual shift. Liquid Glass involved significant cross-team coordination—rendering, accessibility testing, app compatibility and performance tuning—so rolling back or reengineering it would carry material technical and user-experience risks. Given Apple’s stated emphasis on stability for this OS cycle, teams appear to favor incremental fixes that reduce regressions.
Analysis & Implications
From a user-experience perspective, leaving Liquid Glass largely intact reduces disruption for millions of devices already updated to iOS 26. Incremental controls—like additional sliders or toggles—can reconcile aesthetic intent with practical readability concerns without creating fragmentation. However, small fixes may frustrate users who want a faster, more visible response to complaints about contrast and clarity; their demands could persist across multiple release cycles.
For developers, a stable system visual language simplifies design testing and asset planning. Major visual shifts force third-party apps to update styling and navigation affordances; the likelihood of minimal change in iOS 27 lowers the short-term burden on app teams. At the same time, new per-system controls (if implemented) could require developers to account for variable translucency levels in their UI layouts and testing matrices.
Strategically, Apple’s approach signals prioritization: performance and reliability will take precedence over cosmetic revisions in this release window. That choice can be read as a defensive posture against user-visible bugs and industry pressure to maintain smooth operation, especially as hardware transitions and feature parity across devices remain focal points. In the longer term, gradual refinements can preserve the company’s design direction while responding to accessibility concerns.
Comparison & Data
| OS Version | Liquid Glass change |
|---|---|
| iOS 26 | Introduced Liquid Glass as central UI motif |
| iOS 26.1 | Added ‘Tinted’ option for glass appearance |
| iOS 26.4 | Added option to disable Liquid Glass highlights |
| iOS 27 (internal) | Minor tweaks visible; no major redesign in internal builds |
The table summarizes visible product changes to Liquid Glass across recent releases and current iOS 27 internal builds. The pattern shows Apple favoring iterative controls (Tinted, highlight disable) and exploring broader customization (systemwide slider) while avoiding abrupt visual reversals.
Reactions & Quotes
Gurman reports that current internal builds ‘do not reflect major design changes’ and that Liquid Glass will see slow, incremental refinement.

Unconfirmed
- Whether a systemwide translucency slider will ship in iOS 27 remains unresolved; Apple has only prototyped it and faced cross-surface engineering hurdles.
- How extensively the new design lead will alter Liquid Glass’s visual rules is unclear; internal plans may change before public release.
- The timing and scope of any final user-facing tweaks for iOS 27 could shift as Apple prioritizes stability and performance.
Bottom Line
Apple appears set to keep Liquid Glass as a design direction rather than reversing or radically redesigning it in iOS 27. The company has instead added targeted customization options since the feature’s debut and is considering additional controls, but internal builds suggest only modest refinements are likely for the next release.
For users and developers, the practical outcome is continuity: fewer surprises and more focus on performance and bug fixes this cycle. Accessibility and readability concerns remain valid, and Apple’s plan for gradual improvement means those issues may be addressed over multiple releases rather than in a single update.
