1. Adjust the LaunchPad icon to display the number of columns and number of rows

1. Adjust the number of icons displayed in each column. On my computer (1366*768), seven people in each column thought it was good: defaults write com.apple.doc k springboard-rows-int 72. Adjust the number of icons displayed on each row, here, I used 6 defaults write com.apple.doc k springboard-columns-int 63, restarted the Dock killall Dock4, and changed the number of icons displayed on each page, you may need to reset Launchpad (this step is generally not required) ults write com.apple.doc k ResetLaunchPad-bool TRUE
