Apple's macOS 27 may finally get Liquid Glass right on the Mac
Apple is planning a visual cleanup for macOS 27 , addressing the transparency and shadow issues that made its Liquid Glass design feel half-finished on Mac. According to Bloomberg's Mark Gurman in his Power On newsletter, the company internally calls it a "slight redesign"—not a reinvention, but a correction.
The core problem? Liquid Glass was built with OLED screens in mind—the kind found on iPhones and Apple Watches, where translucency and depth effects pop. Most Macs, however, still run on LCD displays, which simply don't render those effects as crisply. Throw in the MacBook Air's 2022 chassis and the iMac's 2021 design, and you've got new software running on aging hardware it wasn't really designed for.
The result showed up most noticeably in places like Control Center, Finder sidebars, and dense list views—areas where Tahoe's transparency made text genuinely harder to read.
The design was right. The engineering wasn't quite there yet.Gurman's reporting makes an interesting distinction: this wasn't a design failure. It was an implementation problem. The macOS 27 tweaks are meant to deliver Liquid Glass the way Apple's design team originally envisioned it—the software engineering just didn't get there in time for Tahoe's launch.
It's a familiar Apple pattern. After the flat redesign of iOS 7 in 2013, the company spent the next year quietly polishing rough edges with iOS 8. History appears to be repeating itself.
Beyond aesthetics, macOS 27 will push reliability and performance improvements—better battery life, fewer bugs, cleaner code across the board. Think iOS 12 energy, but for the Mac.
Siri will get a proper overhaul, and Safari could learn a neat new trickThe bigger feature headline across both macOS 27 and iOS 27 is a revamped Siri—rebuilt with a chatbot-style interface, deeper Gemini integration, and a unified Siri-and-Spotlight experience. Apple is also letting users choose rival AI models across Apple Intelligence features.
Safari, meanwhile, is testing automatic tab grouping. You tap "Organize Tabs," let the system sort by topic, and suddenly your 47 open tabs become someone else's problem to manage.
Apple will officially pull back the curtain at WWDC on June 8.
