I am trying to empty the trash which has a large number of files in it. I am getting an error code -8003. Secure empty trash doesn't help. I really need to empty the trash. Was does this error code mean?
This answer is a bit late to the table, but try holding down the "Option" key when emptying the trash.
Make sure you're closed out of any open applications. If that doesn't work, restart your computer, make sure any auto-launch applications are closed, and try holding down Option again while you empty the trash.
You have to hold the Option key down the whole time you are executing the command, but you can let go once the trash begins to empty.
