WhiteSur GTK Theme is a GTK theme that applies macOS-style visual design to Linux desktop environments using GTK.
The theme addresses the desire to bring macOS aesthetics to GTK-based desktops by providing comprehensive CSS styling for GTK applications. It works by replacing the default GTK theme with custom stylesheets that emulate macOS appearance across supported GTK versions. The project includes an installation script that handles dependency management and offers customization options during setup. It also provides optional tweaks for GDM theming, Firefox integration, and Flatpak application styling.
Developers and users seeking a cohesive macOS-like visual experience on GNOME or other GTK-based desktops should consider this theme. It suits anyone running a GTK desktop environment who prefers Apple's design language. The project acknowledges a limitation with libadwaita applications introduced in GNOME 43 and later: because libadwaita does not support custom themes, the tool can only apply styling by overwriting GTK 4 configuration files, which prevents switching between themes or toggling dark mode for affected applications without manual reconfiguration.
The project maintains active development with regular updates to support new GTK versions and GNOME releases. Installation and uninstallation are straightforward through provided shell scripts. The maintainer actively engages with users through donation options and provides detailed documentation for both basic installation and advanced customization scenarios.
