macOS 26 Critics say the new UI Feels Cluttered and Inconsistent

Apple’s macOS 26 “Tahoe” arrives with Liquid Glass, a system-wide redesign that makes the menu bar fully transparent, rounds window corners, and introduces floating sidebars and toolbars across core apps. It’s a bold swing meant to unify Apple’s platforms — but the rollout is exposing design seams that heavy Mac users can’t unsee.



The pain points users call out



On Reddit, the biggest flashpoint is Finder’s new floating sidebar, which creates a “double bezel” effect — a secondary border inside the window that some describe as un-modern and visually noisy. Others point to mismatched corner radiuses, uneven toolbar heights, and finicky padding that make adjacent windows feel like they come from different OS builds.



Even Apple’s own apps don’t always match perfectly. Compare a redesigned app with a compact, minimal title bar (like Terminal) against one with a fuller, button-rich header: the corners and top chrome can look different. The effect is magnified when a third-party app hasn’t yet adopted the new components.



Apple’s intent — and where it lands today



Apple’s documentation is explicit: windows are rounder, the menu bar is fully transparent, and sidebars/toolbars use Liquid Glass to “reflect and refract” content while drawing focus to what matters. Apple also allows tinted and even clear app icons, which changes how the Dock reads at a glance. The theory: more cohesion with iOS/iPadOS and a lighter, content-first feel. The practice: some users see clutter and lost hierarchy, especially on large monitors with many overlapping windows.



Why it looks inconsistent right now



Two simple reasons:




Framework adoption lag. Until developers rebuild toolbars/sidebars with the new APIs, their apps retain the old chrome — so mixed setups clash.



Radius-by-context. In the new system, the corner radius can vary with the window’s header elements (think: concentric curves), so not every app will share the same corner treatment.




What to expect next



Historically, Apple sands down rough edges in early point releases, while app makers gradually re-skin to the latest HIG. If that happens here, Tahoe should feel more consistent by default — without Apple having to freeze the design. Until then, the “double bezel” aesthetic and mixed chrome will remain the flashpoints to watch across the next few updates.
