Your MacBook Pro laptop uses the same method to delete applications as other Apple computers running the Mac OS X operating system. Applications are stored in the Applications folder on Mac OS X by default. If you need to create more space on your MacBook hard drive, deleting applications you no longer use is an effective way to do so. To delete an application on your MacBook Pro, transfer it to the Trash folder.
Click the "Finder" icon in the Dock. The icon looks like a blue, smiling face.
