Change Launcher Layout in OS X With Terminal Command
Don’t like Launchpad’s standard five-by-seven grid for displaying apps? Defaults-write indicates that you can change it to pretty much anything you want with a terminal command.
As you would expect, here you need two terminal commands, one for columns and one for rows. So, start by opening Terminal (Applications> Utilities). Then, for the columns, enter the following command, replacing X with whatever number you like:
by default we write com.apple.dock springboard-columns -int X
Then you will do the same for the lines, again replacing the number of your choice with X:
by default write com.apple.dock springboard-rows -int X
When you’re done, restart Launchpad with this command:
by default we write com.apple.dock ResetLaunchPad -bool TRUE; killall dock
And that’s it, your Launchpad is customizable to your liking. Go to Default-write to find out more.
