Add Blank Space Invisible Icon In Mac OS X Dock

The dock is a wonderful way to manage, launch and view the status of your favorite applications. Although I primarily use Quicksilver to launch applications, as do many other Mac users (probably other similar applications such as Alfred or built-in Spotlight), but a lot of people like to use the dock for a few of their most-used applications. Also, the dock displays a light under all running application icons and is therefore an indispensable tool for any user who wants to view if an application is running or not.

However, categorization of applications isn’t possible in the dock. You may create folders to store apps, but then you need to do multiple clicks to launch an app. There is a workaround for this: you can separate apps from different categories in the dock by a blank spacer icon.

Adding a blank space is relatively simple, just launch using Spotlight or go to Applications >> Utilities >> Terminal.

Now type in:

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

This command adds a blank ‘spacer tile’ to the dock. But you won’t be able to see the changes made immediately. To see the changes, type:

killall Dock

You should be able to see a blank space now in the dock. Just like any other icon, you can drag this spacer tile to an appropriate position for categorization of your apps. You may add as many spacer tiles as you like by repeating the above steps.

To remove a spacer tile, just drag it out of the dock and drop it anywhere. It will disappear in a poof just like a normal icon.
