How to add space separators between icons in macOS DOCK?

You can customize your macOS Dock by adding invisible spacer icons to organize apps. Here’s how to do it using Terminal commands:

---

Method 1: Adding a Small Spacer

This adds a flexible, small gap between Dock icons.

1. Open Terminal (⌘ + Space → Type Terminal → Enter).
2. Paste & run this command:

defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="small-spacer-tile";}'

3. Restart the Dock to apply changes:

killall Dock

Method 2: Adding a Large Spacer

This adds a bigger, fixed-width gap (like a divider).

1. Run this in Terminal:

defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="spacer-tile";}'

2. Restart Dock:

killall Dock

How to Remove Spacers from your Dock ?

• Drag the spacer out of the Dock (it will disappear with a puff animation).
• OR reset the Dock to default (removes all spacers):

defaults delete com.apple.dock persistent-apps
killall Dock
