Apple announced a visual redesign called Liquid Glass, set to debut with macOS 26 Tahoe. This design features transparency effects in context and dropdown menus, system controls, and the Control Center, where elements exhibit a glass-like quality. The dock allows icons to have varying translucency, with options for classic, dark, clear, or tinted versions. However, some inconsistencies exist in the beta version, such as tinted icons lacking transparency. The glass effects are present in many of Apple's apps, with navigation panes on a glass-like surface and floating menu buttons that are translucent.
In comparison, Windows Vista's Aero Glass was noted for its impactful use of transparency in title bars and window borders, creating a sense of depth and enhancing user experience. Although Apple's Liquid Glass is meticulously designed, it may come across as too subtle compared to the more pronounced Aero Glass effects. The impressions of macOS 26 Tahoe are based on the initial developer beta, and improvements are expected before its public release later this fall.
