How to Refresh Launchpad in Mac OS X

Refresh Launchpad in Mac OS X

Launchpad is the app launcher in Mac OS X that is quite like the iOS Home Screen, showing a series of app icons and names on a simple screen making it very easy to launch whatever apps you want to open. It’s a nice utility and feature built into the Mac, but it does have some quirky behavior from time to time. One of those issues is that sometimes apps won’t appear in Launchpad at all, or perhaps when you delete an app it doesn’t disappear from Launchpad as it’s supposed to. If you run into this or any other irregularities with Launchpad, try this great tip left by one of our readers to discover how to refresh Launchpad and all of its contents.

These tricks work to refresh and relaunch Launchpad for all Macs with versions of OS X that include the native feature, including Lion, Mountain Lion, Mavericks, and beyond.

Relaunching Launchpad

Launchpad is attached to the Dock app, so the easiest way to relaunch LaunchPad is to kill the Dock from the command line:

killall Dock

Both the Dock and Launchpad will relaunch and that should clear up most minor issues with app persistence.

How to Refresh Launchpad Contents

If relaunching alone hasn’t fixed LaunchPad and apps are still not showing up, try deleting Launchpads database files located inside your home ~/Library directory, which forces them to rebuild. The directory path you are looking for is:

~/Library/Application Support/Dock/

The fastest way to get there is by using Command+Shift+G in the Finder to access the “Go To Folder” function, then just paste that directory path in. You will see a folder like this:

OS X Lion's Launchpad database files

If you want to back these up you can, otherwise just delete them by dragging all of the .db files to the Trash, and then kill the Dock again from the Terminal to force the databases to regenerate.

killall Dock

Take note that you will lose any custom icon placement and folders that are setup within Launchpad, because that information is stored in the database file you are trashing.

One-Line Terminal Command to Refresh Launchpad Contents in OS X

If you are comfortable with the command line, you can also do this entire process through the Terminal with the following commands:

rm ~/Library/Application\ Support/Dock/*.db ; killall Dock

Be sure to issue that command exactly as written, because the rm command is powerful and will delete everything without asking, and * is a wildcard for any files matching the *.db name (meaning, anything that ends with .db).

If you want control over exactly what shows up in Launchpad rather than just creating a bunch of folders, use the third party System Preference Launchpad Control, it’s free and works as a sql frontend to the Launchpad database.

Again, this works in OS X 10.7, OS X 10.8, OS X 10.9, and newer.

    I hope 10.7.1 resolves the bugs with LaunchPad, I can’t delete over half the apps so I just created a huge folder called MISC that holds everything that I can’t remove manually. Buggy, but I use it more than I thought I would.

  2. David says:

    killall Dock has become my ‘go to’ command with Lion for unfreezing Mission Control. Ah, the pain of early adoption.

  3. Dan says:

    Look at the Launchpad icon. Then look at the blue corner of the game center app icon on your idevice. MIND=BLOWN!!

    Aside my shenanigans, I like the launchpad feature. It’s not really useless. In my opinion it’s a much, much faster way to get to my apps and not one of the useless gimmicks that came with lion.

  4. Joe says:

    THANK YOU, YOU CHAMPION!!!

  5. Nat says:

    I have another problem: when I sort all my apps in folders in Launchpad, each time I install or disinstall something, the mess from the beginning appears (no folders, just pages of apps) so I have to use Launchpad Control each time… is there any hint for this? I’d love to have there my order….

    If for example you changed an icon of an app, instead of killing the dock like I tried and was still unsuccessful at refreshing the launchpad database, or deleting the .db file you can just rename that app and then name it back and that icon will change…

  7. tk says:

    I am not sure if this is related, but i have a similar problem of the icons in launchpad not loading when launchpad opens for atleast 20 seconds so the all just appear as squares. Anyone else have this problem?

  8. Richard says:

    A gui alternative is to use the Activity Monitor and go to the “dock” process and quit it. I had a folder that was not showing anything but the dashed lines around it. Anytime I clicked on it launchpad would exit. This fixed it the same as the command “killall dock”.

  9. Flex says:

    It doesn’t work.

  10. Deepak says:

    Works fine for me. Thnx

    I’m still estranged as to why Apple haven’t thought of including a separate system preferences to launch pad. I, myself, is one of many within my network who can see the possibilities in the Launch Pad app, but I still find it to be a mess in many ways. Hope there’ll be a fix soonish. Although I wouldn’t be surprised to see the fix being Mountain Lion only, which I’ve been dreading since Lion. God, have I dealt with many issues regarding Lion.

    Thanks .. It worked the way I wanted it. You are awesome

  13. Michael says:

    How do I use the killall command? Someone help :/

  14. Ashok Maurya says:

    Excellent tutorial. Just need to share. It shows:
    1. Applications distributed by Apple in alphabetical order,
    2. Applications installed for all users in alphabetical order, 3. Any minor apps installed in other directories for all users(like subdirectories in Utilities),
    4. Applications installed for current users only

    Of course you can do manual changes as well for any change in order. Thanks
