In this short tutorial I’m going to show you how to set you Trash Can on Mac OS to automatically fully remove items after 30 days.
Firstly you want to the Menu bar at the top of your Mac.
Click on the ‘Finder’ link. A menu will drop down.
Click on ‘Preferences’. You will then be shown the ‘Finder Preferences’ dialogue box.
Click on ‘Advanced’
You will see a check box option ‘Remove items from the Trash after 30 days’
Simply check this box. This will help to keep your Trash nice and clean.
