Automatic process

You can also set up your Mac to empty the Trash automatically after a certain period. To enable this feature, open Finder, click on “Finder” in the menu bar, and select “Preferences.” Navigate to the “Advanced” tab and check the box next to “Remove items from the Trash after 30 days.
