Liquid Glass in macOS: what happened to the menu bar and its icons

People arrive at this subject from two opposite directions. Some want more of it and cannot find the switch. Others updated, looked at the top of the screen, and want the wallpaper to stop showing through the row of icons they read all day.

Both groups are asking about the same handful of settings, spread across three panes with no obvious relationship to each other. And both are dealing with a change that is broader than a theme, because the material affects what is drawn behind every status icon on the machine.

What Liquid Glass actually is

It is a material, not a colour scheme, and Apple describes it in physical terms.

That distinction has a practical consequence. A theme has a fixed appearance that can be memorised. A translucent material takes its appearance from whatever is behind it, which means the same icon is legible on one wallpaper and marginal on another, and neither case is a bug.

The change arrived across Apple's platforms at the same time, announced in a press release dated June 9, 2025, covering iOS 26, iPadOS 26, macOS Tahoe 26, watchOS 26, and tvOS 26. Anyone still on macOS Sequoia 15 or earlier will not see any of it, and no setting will produce it, because the material is part of the newer system rather than an option inside the old one.

On the Mac, the menu bar took the biggest hit

Among all the surfaces the material touches, one Mac specific change was singled out in the announcement itself.

The reasoning is sound. Removing the bar's background removes a visible horizontal band, and the screen reads as taller. The cost lands on the strip's contents rather than on the strip itself, and it is not distributed evenly. App menus on the left are text, in a single weight, and text survives a busy background reasonably well. Status icons on the right are small shapes, often thin outlines, sometimes carrying a number, and a photograph directly behind them removes the contrast they were drawn to rely on.

This is why the complaint is almost always about the right half of the bar and almost never about the File menu. It is also why the fix people reach for first, changing the wallpaper, works better than it has any right to.

What macOS 27 changed

The current release revisited the material rather than reverting it.

Updates to Liquid Glass ensure exceptional readability with more uniform refraction and improved contrast. Uniform toolbars, edge-to-edge sidebars, and updated window shapes and menu bar icons deliver a more refined design. And a new slider lets you easily customize how Liquid Glass looks, from ultraclear to fully tinted. Source: apple.com, read September 28, 2026

Three things in that paragraph matter for the top of the screen. Refraction is described as more uniform, which addresses the case where the same element looked different depending on what sat behind it. Contrast is described as improved. And menu bar icons are named explicitly as having been updated, which is the reason a familiar icon can look subtly wrong after upgrading while nothing about the app has changed.

The slider is in Appearance settings, and Apple's own description of it is narrower than the marketing line suggests: it adjusts the appearance of app icons. It is a genuine control over how glassy the system looks, and it is not a menu bar transparency switch.

The controls, from gentlest to bluntest

Five settings affect how much of the material is visible, and they live in three different places. Knowing which one is being reached for saves a long tour of System Settings.

Setting	Where	What it affects
Show menu bar background	Menu Bar settings	Draws a background under the strip instead of the wallpaper
Liquid Glass slider	Appearance settings	App icons, from clear through to the heaviest tinting
Icon and widget style	Appearance settings	Default, Dark, Clear, or Tinted for icons and widgets
Tint window background with wallpaper color	Appearance settings	Toolbars and status bars pick up wallpaper colour
Reduce transparency	Accessibility, then Display	Transparent areas system wide become solid grey

The first is the one that answers the common complaint directly.

It is a single control in the Menu Bar pane of System Settings and it only affects the strip, which is exactly the desired scope for anyone who likes the rest of the design.

The fourth is worth knowing about because it is frequently mistaken for the material itself. Allowing colours from the wallpaper to tint toolbars and status bars produces the impression that windows have gone slightly translucent when nothing of the kind is happening.

The last is the heavy option.

Reduce transparency is an accessibility setting and it behaves like one. It applies everywhere at once, it is completely reliable, and it undoes the look the last two releases were designed around. For anyone who reads the menu bar hundreds of times a day, that trade is often worth making. It can also be toggled quickly, since Apple lists Reduce Transparency among the accessibility features available from the Accessibility Shortcuts panel.

Icon and widget style, and what Clear really does

The setting people actually mean when they say they turned Liquid Glass up or down is usually this one, sitting directly under the slider in Appearance settings. It has four options and they are not degrees of the same thing.

Option	What the items look like	Extra choice
Default	Opaque, with a light or coloured background depending on the app	None
Dark	Opaque with a darkened appearance	Always, or Auto to follow the system appearance
Clear	Transparent	Light, Dark, or Auto
Tinted	Opaque against a dark background	The colour chosen for the theme

Clear is the one that produces the screenshots, and it is also the one that costs the most legibility, because a transparent icon over a detailed wallpaper has very little left to distinguish it. Tinted goes the other way and is the quiet recommendation for anyone who wants the new look without the guesswork, since every icon ends up in one deliberate colour against a dark background rather than borrowing whatever happens to be behind it.

Two neighbouring options complete the set and are easy to confuse with the material. Folder color changes Finder folder icons, and appears when Default, Dark, or Clear is selected. When Tinted is selected it is replaced by a single control covering icons, widgets, and folders together. Neither has anything to do with transparency.

None of these four options touches the menu bar. They govern app icons and widgets, which live on the Dock and the desktop. That separation is the single most useful thing to know before spending twenty minutes in Appearance settings looking for a menu bar control that is in a different pane entirely.

Why third party status icons look uneven

Under a solid bar, inconsistency between icons was invisible. A slightly heavy icon, a coloured one, one drawn a couple of pixels larger, all looked fine against grey. Remove the background and the differences become the most noticeable thing on the screen.

There are three separate causes and they need different responses.

The first is that each app supplies its own status item artwork. Apple's system items were redrawn for the new design, and third party items were redrawn only if their developers did the work. A mixed bar during the first year of a design change is normal rather than a fault, and the remedy is app updates.

The second is contrast against an unpredictable background. An outline icon designed for a grey bar has nothing to fall back on over a dark photograph. This is the case the menu bar background setting exists for.

The third is width, which the new design makes more visible without changing.

Because there is limited space in which to display status items, status items are not guaranteed to be available at all times. For this reason, do not rely on them being available and always provide a user preference for hiding your application's status items to free up space in the menu bar.

A transparent bar shows the wallpaper in the gaps, so a crowded strip now reads as a crowded strip rather than as a neutral grey band. The number of icons did not change. Their visual weight did. Deciding which of them earn permanent space is the change that survives the next design revision, and the features page covers what a menu bar organizer does with the rest.

If Liquid Glass is missing entirely

Two situations produce a Mac with none of this, and they need different answers.

The first is the macOS version. The material arrived with macOS Tahoe 26 and continues in macOS 27 Golden Gate. On macOS Sequoia 15 or anything earlier, there is nothing to enable. Checking is a matter of opening About This Mac, and the Mac User Guide itself offers a version selector that makes the difference obvious, since the Menu Bar pane described here exists in the macOS 27 edition and not in older ones.

The second is that an accessibility setting is already on. Reduce transparency turns the material off convincingly enough that it looks like the update never applied. It survives macOS upgrades, and on a machine set up by someone else, or migrated from an older Mac, it is frequently on without anyone remembering switching it. That is the first thing to check before concluding the design did not arrive.

A third possibility is narrower and worth naming. The Liquid Glass slider is described as affecting app icons, so somebody expecting it to control window translucency will conclude it does nothing. It is working. It is answering a different question, and the FAQ covers what changes and what does not when the appearance settings move.

What to change first

If the menu bar is the problem, open Menu Bar settings and turn on the menu bar background, which fixes the strip and leaves the rest of the design alone. If the whole system feels hard to read, use Reduce transparency in Accessibility instead, and accept that it applies everywhere. Either way the underlying question is how many icons the strip is carrying, and a tool such as Koffret is what reduces that number without giving any of them up.
