15 Mac Dock Tips: Customize, Speed Up, and Master Your Dock

The Dock is one of macOS's most-used interfaces, but most people never go beyond the basics. Here are 15 tips to make it work better for you.

Speed and animation

1. Remove auto-hide delay When you move your cursor to the bottom of the screen, there's a slight delay before the Dock appears. Remove it: ```bash defaults write com.apple.dock autohide-delay -float 0 killall Dock ```

2. Speed up the animation The Dock slides in slowly by default. Make it snappy: ```bash defaults write com.apple.dock autohide-time-modifier -float 0.15 killall Dock ```

3. Enable auto-hide If you haven't already, auto-hiding gives you more screen space: System Settings > Desktop & Dock > Automatically hide and show the Dock.

Or: Cmd+Option+D to toggle.

Layout and organization

4. Add spacers You can add invisible spacers to visually group Dock icons: ```bash defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="spacer-tile";}' killall Dock ``` Repeat for multiple spacers. Drag them to reposition.

5. Show only active apps Hide all pinned apps and show only what's actually running: ```bash defaults write com.apple.dock static-only -bool true killall Dock ``` Revert with `defaults delete com.apple.dock static-only && killall Dock`.

6. Dim hidden apps Make icons of hidden (Cmd+H) apps translucent: ```bash defaults write com.apple.dock showhidden -bool true killall Dock ```

Keyboard shortcuts

7. Switch between apps Cmd+Tab shows the app switcher. But you can also: - Cmd+Tab then Q to quit the highlighted app - Cmd+Tab then H to hide the highlighted app

8. Show a specific app's windows Click and hold an app's Dock icon to see its windows. Or three-finger tap on trackpad.

9. Quick Look from the Dock Click and hold a folder in the Dock to see its contents in a fan, grid, or list.

Folders and stacks

10. Add custom folders Drag any folder from Finder to the right side of the Dock (to the right of the separator line). Right-click the folder in the Dock to set display mode: - Fan — shows items fanned out - Grid — shows a grid of icons - List — shows a scrollable list - Automatic — Dock decides based on item count

11. Set the Dock folder sort order Right-click a folder in the Dock > Sort by: Name, Date Added, Date Modified, Date Created, or Kind.

Advanced

12. Move the Dock to the side System Settings > Desktop & Dock > Position on screen: Left, Bottom, or Right.

Left is popular among developers — it saves vertical space on widescreen displays.

13. Change Dock icon size System Settings > Desktop & Dock > Size slider. You can also hover over the Dock separator and drag up/down to resize.

14. Disable bounce animation Stop apps from bouncing their Dock icon for attention: System Settings > Desktop & Dock > Disable "Animate opening applications."

15. Reset the Dock to defaults If you've experimented too much: ```bash defaults delete com.apple.dock killall Dock ``` This restores all Dock settings to macOS defaults.

Apply tweaks with one click

Remembering Terminal commands is tedious. CleanMyMacOS includes Dock tweaks (auto-hide delay, animation speed, active apps only, dim hidden apps) as simple toggles. Each shows the current state, can be toggled instantly, and supports one-click revert to defaults.

CleanMyMacOS can help with this — download it free from the Mac App Store.
