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.
