1. Triple-click anywhere in the line below on this page to select it:
~/.Trash
2. Right-click or control-click the highlighted line and select
Services ▹ Show Info in Finder (or just Show Info)
from the contextual menu.* An Info dialog should open.
3. The dialog should show "You can read and write" in the Sharing & Permissions section. If that's not what it shows, click the padlock icon in the lower right corner of the window and enter your password when prompted. Use the plus- and minus-sign buttons to give yourself Read & Write access and "everyone" No Access. Delete any other entries in the access list.
4. In the General section, uncheck the box marked Locked if it's checked.
5. From the action menu (gear icon) at the bottom of the dialog, select
Apply to enclosed items
and confirm.
6. Close the Info window and test.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. Open a TextEdit window and paste into it (command-V). Select the line you just pasted and continue as above.
