Windowcase

Windowcase draws real materials around every window on your Mac, from walnut and marble to brushed aluminium, leather, carbon fibre and circuit board. It includes 14 textures, and you can give unfocused windows a separate look with no border, the same texture or a different one. Thickness and corner style are adjustable, and optional animations add a glint when a window gains focus and a slow shimmer on metal textures. Borders hide automatically in Mission Control and full-screen apps, and you can exclude apps like games, video players or screen sharing. Textures can switch with light and dark mode or on a day and night schedule, and it lives quietly in the menu bar without needing Accessibility or Screen Recording permission. Key Features: - 14 Textures: walnut, marble, aluminium, leather and more - Focus Styles: different looks for focused and unfocused windows - Custom Borders: adjustable thickness and corners - Subtle Animations: focus glint and metal shimmer - Smart Rules: excluded apps and light/dark schedules Windowcase adds a tactile, crafted touch to every Mac window, for a one-time price of $4.99 with open source code under GPL-3.0.
