There are users who have the Mac dock really full of applications and at first it can be a bit more difficult to find one or another application if we are not used to it. For this type of users who fill the application bar there is a little trick to be able to better locate or group it, add spaces in the dock. This that a priori may seem very complicated to carry out is as simple as placing in Terminal a line or command that we are going to leave after the jump so that everyone can carry it out.
For leave a space on the left where all the applications go you need to copy and paste this command in Terminal:
defaults write com.apple.dock persistent-apps -array-add '{tile-data = {}; tile-type = »spacer-tile»;} '
This is the command to clear the dock on the right side just after the applications. If we look, the word changes «Others by apps»
defaults write com.apple.dock persistent-others -array-add '{tile-data = {}; tile-type = »spacer-tile»;} '
In both cases followed by the directly copied command to create the spaces, you need to type the following terminal command "Killall Dock" without the quotes to make it work.
You can try this trick for the dock bar without problem since To eliminate the space that we have created, it is as simple as clicking with the right button of the mouse on it and removing it from the dock as if it were an application. This little trick has been in OS X for a long time and without a doubt it can be interesting for those who accumulate many applications to have a space and find better the one we are looking for, for those who do not have many applications we do not think it is so useful but it can be used No problem.
