Organize your Mac's Dock with spacers

With a Terminal command, you can add spacers to the Mac OS X Dock, helping you group similar apps for a more organized look.

This might be a tip only the Anal-Retentive Chef could love, but I kind of like it. If you'd like to add a bit of order and structure to your Mac OS X Dock, there is a way to add spacers, which let you separate the various icons into distinct groups.

To do so, open Terminal and then copy and paste this command:

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

Followed by:

killall Dock

The command places an invisible space on the right side of your Dock. You can drag to reposition this spacer in the Dock, and if you'd like to get rid of it, just drag it off the Dock. You can re-enter the above Terminal command to add another spacer, or you can enter the command multiple times before entering "killall Dock" to add multiple spacers at one time.
