Is it possible to reset launchpad layout? My launchpad has become very cluttered overtime. I'm wondering if there is a function to reset launchpad like the iOS reset home screen layout feature. Let me know in the comments if you don't understand what I'm asking.
To reset Launchpad to the default, delete the following file:

/Users/$USER/Library/Application Support/Dock/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx.db



Where "xxxx..." in the file name is an alphanumeric string.


And then run the following command in a Terminal:

 killall Dock


The Launchpad is now reset to the default and a new database (.db file) will be created with the default settings.

Note:  If you want to examine the contents of the database you can use an app like Liya.
