644: You Have to Invert

What It Covers

The hosts evaluate macOS Tahoe and iOS 26 beta one after one week of use, focusing on the liquid glass design system, usability challenges with transparency effects, Safari's dynamic color switching, and Apple's three-year roadmap for Rosetta two compatibility.

Key Questions Answered

• •Liquid Glass Transparency Issues: The new material causes text on buttons to flash between black and white as content scrolls behind them, with a noticeable lag creating a distracting strobe effect. Apple's guidance says to avoid overusing it, yet their own apps apply it extensively over arbitrary scrolling content.
• •Safari Usability Regression: The entire Safari toolbar switches between light and dark modes based on webpage content color, changing with every tab switch or page navigation. The redesign also adds extra taps for common actions like opening new tabs, now requiring users to first access a more menu.
• •Rosetta Two Sunset Timeline: After macOS 27 ships in 2026, Rosetta will only support a limited subset of older games using Intel-specific libraries. All other x86 applications on Apple Silicon Macs will stop launching, affecting apps that developers never updated for ARM architecture despite working fine today.
• •Design Consistency Problems: Apple's own Music app displays horizontal scrollbars above the now-playing controls due to the floating element philosophy. Window traffic lights appear inconsistently—sometimes in the sidebar, sometimes on top of it, sometimes inline with content—with no coherent layering logic across different window configurations.
• •Beta Performance Reality: iOS 26 beta one runs extremely slowly on iPhone 16 Pro with janky animations, rendering bugs, and sluggish performance nowhere near 60fps. The redesign scope appears so extensive that shipping a polished version by September seems questionable given the current state and remaining development time.
