If you've been using your Mac for a while, you've probably accumulated a lot of shortcuts in your Dock, which can make finding things difficult. Adding a blank space or two is a great way to organize apps into groups.

A blank space on the Dock is just that: nothing. When you click on it, it won't do or launch anything. They just let you scan your eye along your icons so you'll be able to better make out your applications.

To begin, you first need to fire up our trusty old Terminal, which can be found in the Applications > Utilities folder.

Now that your Terminal is open, you're going to want to type or paste the following command, and then hit Enter:

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

Now type the command:

killall Dock

Make sure to press Enter again. The procedure will look like this in your Terminal.

If you want to repeat this so as to add more spaces, you don't need to keep reentering the same information in the Terminal over and over, you can simply repeatedly tap the Up Arrow to recycle the commands.

Now we have added three blank spaces to our Dock. You can add as many spaces as you like or will logically fit.

Once you've created a few spaces, you can drag them into place and also rearrange your application icons to compose your groups.

If you decide you no longer want or need a blank space, simply grab it with your mouse pointer like you would anything else on the Dock and drag it off until you see "Remove".

That's it, now you have a really simple procedure for organizing your Dock icons into visually manageable application groups.

It's a shame Apple doesn't include this ability via a simpler method, but at least it can be done. So, now you'll have a much more organized Dock and be able to launch your applications without hunting for them first.
