Respect Dock Space

When a fixed dock is on a screen edge, Respect Dock Space prevents app windows from overlapping it when they expand.

How it works

When you zoom (green button) or double-click a window’s title bar to expand it, macOS normally fills the entire screen. With Respect Dock Space enabled, ExtraDock detects the overlap and resizes the window to fit the available area — leaving room for your fixed dock.

This only applies to fixed mode docks.

Enabling it

Management window → Properties → Behavior → Respect Dock Space

Or globally for all fixed docks:

Open ExtraDock → Settings (⚙) → General → Dock Behavior → Respect Dock Space

Active on drag

By default, windows are only corrected on expand-style resizes (zoom, double-click). Enable Active on Drag to also correct windows after manual drag or resize operations.

Open ExtraDock → Settings (⚙) → General → Dock Behavior → Active on Drag

Accessibility permission

This feature requires macOS Accessibility permission to detect and reposition other app windows.

System Settings → Privacy & Security → Accessibility → add ExtraDock.

ExtraDock will prompt you to grant permission when you enable the feature.
