After upgrading to Mavericks from Lion, I’ve noticed that it boots faster, but when after logging in, Launchpad runs slower with Loading Application text until you wait ages for it to load.
I’ve found out about how to rebuild your Launchpad Icons thus making desktop loading faster:
Note: Be sure to back-up first before doing this step since you might delete the wrong file.
Open Finder, and click on the Home Folder on your Sidebar on the left (The one with the username under Favorites).
From the View Menu (on the Menu Bar above), click Show View Options, and check Show Library Folder.
Then from your home folder, there is now a Library folder and navigate to:
Library->Application Support->Dock.
Library->Application Support->Dock.
Delete the other file with the .db extension and NOT the desktoppicture.db.
Reboot.
Click the Launchpad icon. This will rebuild the Launchpad icons so, wait for awhile.
Reboot again.
And, there you have it. The desktop boots faster since it removed the entries that are not needed. You may want to un-check Library folder view from Finder by doing the steps mentioned above.
That’s it!
