In OS X Lion, apps still live in your Applications Folder, though Launchpad was designed to be your go-to app manager. When you download an app from the Mac App Store, one of the best parts is watching it fly right into Launchpad. But what happens when you want to get rid of it? To delete an app from Lion, make sure you are logged in as an administrator and enter in Launchpad. Click and hold an icon until the rest start to bounce around, just like in iOS. Click the “x” in the upper left-hand corner of the app icon to delete it, and then confirm that you’d like to banish it. You’ll need to find a way back into Library.
There a few different ways to do this, some more invasive than other. For temporary access, though, this is a fairly elegant solution: Hold down Command + Shift + G from the Mac desktop and type in ~/Library. Finder will then launch to your user Library. Look for files that include the name of the app you just kicked to the curb. For instance, try these locations:
~/Library ~/Library/Application Support
If you find any files with the name of your unwanted app, all you need to do is drag the file into Trash. But proceed with caution: If you are unsure about whether or not you need the file, just leave it in place. Deleting a necessary file could seriously harm your system. At last, When you are down your deleting rampage, don’t forget to empty your Trash to complete the process. If you get a message that an item you are trying to delete is “in use and can’t be deleted” just reboot your Mac and try to empty your Trash again.
