Apple is already preparing to soften the rough edges of Liquid Glass, the interface style it introduced with macOS Tahoe. According to Mark Gurman, macOS 27 will bring a slight redesign focused on readability, cleaner transparency, and a more polished Mac experience when Apple reveals the update at WWDC 2026 on June 8.
Liquid Glass is staying, but the rough edges are getting cleaned up
Apple does not appear to be backing away from Liquid Glass. Gurman says the design team wanted the interface to look cleaner and more refined than the version that shipped in Tahoe. The issue, as described in the report, was less about the design direction itself and more about how it was implemented in software.
That explains why macOS 27 is reportedly aimed at fixing specific pain points rather than replacing the whole look. Apple is working on shadows, transparency behavior, and other visual quirks that made parts of the Tahoe interface feel harder to read than they should have been.
Apple is dialing back the transparency that hurt readability
Tahoe’s biggest problem was not that Liquid Glass looked different. It was that some of its effects got in the way. Sidebars and app surfaces could appear too transparent, making text and controls harder to read on certain Mac displays.
macOS 27 is expected to reduce some of those aggressive effects. That should make the interface feel calmer and more consistent, especially in apps where glassy panels and layered backgrounds made contrast worse.
Apple is also using macOS 27 to clean up performance
The update is also expected to arrive with broader software cleanup across Apple’s platforms. Gurman says code cleanup is a major internal theme for macOS 27 and iOS 27, with Apple likely to talk about better performance and longer battery life during the keynote.
Safari may get one of the more visible feature additions. Apple is reportedly testing an AI-powered Organize Tabs feature that can automatically group open tabs across macOS 27, iOS 27, and iPadOS 27. Test builds already include a setting that lets users decide whether automatic grouping stays on.
Apple is expected to unveil macOS 27 during the WWDC keynote on June 8, with the first developer beta likely arriving the same day. For Mac users who found Tahoe’s Liquid Glass too busy or hard to read, macOS 27 sounds like the version meant to make the design feel finished.
