Background#

Each dock's background can use Liquid Glass, a blur material, or a solid color.

Open the management window → Properties → Appearance → Background to access these settings.

Background style#

Three styles are available:

• Liquid Glass — The same glass as the macOS Dock
• Blur — Frosted glass effect using macOS visual effect materials (default)
• Solid — Opaque background with a solid color

Liquid Glass#

With Liquid Glass selected, choose a Glass look:

• Clear — The macOS Dock's own see-through glass
• Frosted — The same glass under a soft white veil

On macOS 26 the glass is drawn by the system, with live refraction. On macOS 15 and earlier ExtraDock draws its own glass, without refraction. Liquid Glass draws its own edge, so the border, blur intensity, color, and opacity controls are hidden while it is selected. Switching the style back returns the dock to its previous Blur or Solid settings.

Blur intensity#

When using the Blur style, five intensity levels are available:

• Ultra Light
• Light
• Medium (default)
• Dark
• Ultra Dark

Background color#

When using the Solid style, choose a color from the built-in palette or use the custom color picker.

The color setting is disabled when the Blur style is active.

Opacity#

Controls overall background transparency. Three presets and a custom slider:

• 100% — Fully opaque
• 85% — Slight transparency
• 70% — Noticeably translucent
• Custom — Slide to any value between 0% (invisible) and 100%

Default is 95%.
