Apple is reportedly adjusting Liquid Glass in macOS 27 to improve readability and fix transparency quirks, with WWDC set for June 8.
Apple’s next macOS release isn’t abandoning Liquid Glass—it’s refining it.. In what appears to be a direct response to ongoing user grumbles. the design language is expected to get a “slight redesign” in macOS 27. with reported changes aimed at making the frosted. translucent interface look more consistent across screens and apps.
The push comes after complaints about readability and mismatches between how Liquid Glass appears in different parts of the system.. Bloomberg’s Mark Gurman said the current implementation has struggled to deliver a smooth visual transition on the broader display formats common to desktops and many laptop setups.
A major part of the problem, Gurman reported, is that Liquid Glass was built with OLED technology in mind, while many Macs still rely on LCD panels. That hardware gap can make transparency effects behave differently, leaving users to notice odd visual artifacts rather than a uniform look.
Apple’s reported goal in macOS 27 is to tackle those “shadows and transparency quirks” that can show up with Liquid Glass.. The software changes are intended to better align the effect with how Apple’s design team wanted it to present from the beginning—suggesting that the current experience may not fully reflect the intended styling.
Gurman also framed the issue as a matter of engineering maturity rather than purely design intent. attributing the trouble to “a not-completely-baked implementation” from Apple’s software engineering side.. In other words. the interface language may have been designed with one set of display characteristics in mind. but the delivery across macOS hardware appears to have lagged behind.
Meanwhile, the fixes may also matter for what’s next on the hardware side.. Gurman said the Liquid Glass interface could look substantially better on an expected OLED touchscreen MacBook that could arrive as soon as this year—again tying the software behavior to the display technology it was originally optimized for.
This would not be the first time Apple has adjusted Liquid Glass.. Since iOS 26.1, iPadOS 26.1, and macOS 26.1, Apple added an option to frost the interface for more opacity and contrast.. That change gave users a way to reduce the transparency-driven variability. while also implicitly acknowledging that Liquid Glass can be harder to read or less consistent depending on conditions.
Beyond the reported Liquid Glass redesign, Apple is also working on additional system improvements for the next macOS. Gurman said the update plan includes bug fixes, battery-life upgrades, and performance improvements, suggesting that the release will be about more than visuals alone.
All of these changes are expected to be officially unveiled at the next WWDC on June 8. For users, the timing is significant: if Apple is indeed refining Liquid Glass in macOS 27, it may be preparing the experience for both today’s mixed-display fleet and the next wave of OLED-focused devices.
