If you’ve got loads of apps on the dock, visually separating them into groups of similar apps can be useful.
To do that,
- Open Terminal,
- use
defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="spacer-tile";}'; killall Dock.
Now, a space pops up on your dock. Drag it across the dock to separate one set of apps.
Keep repeating the command to create more spaces and segregate more groups.
To remove a space: Use right-click < Remove from Dock (just as you do for an app).
#2. Use Dock with keyboard
If you’re a productivity freak who hates leaving the keyboard and using mouse or trackpad, you’ll love this.
- Use fn + ??? + F3 to trigger dock,
- Use ← or → arrows to move across icons,
- Hit return to open an app.
