You want to delete several applications by dragging them to the Trash.

Some applications install files outside the Applications folder, so dragging an app to the Trash may not remove all of its files.

User data for apps purchased in the Mac App Store will also be deleted when the app is dragged to the Trash.

You must restart the Mac in order to permanently delete applications from the Trash.

Apps purchased in the Mac App Store cannot be dragged to the Trash.
