Apple - How to reset Launchpad ordering in OS X Yosemite?
Enter this line in the console:
defaults -currentHost write com.apple.dock ResetLaunchPad -bool true; killall Dock
Removing the db doesn't seem to do the trick any more. So this two steps are necessary to reset the Launchpad in Yosemite:
- rm ~/Library/Application\ Support/Dock/*.db ; killall Dock
- defaults write com.apple.dock ResetLaunchPad -bool true; killall Dock
rm ~/Library/Application\ Support/Dock/*.db
rm "/$TMPDIR../0/com.apple.dock.launchpad/db/db*"
defaults write com.apple.dock ResetLaunchPad -bool true; killall Dock
