Open QuickTime, select the File menu and the Open Recent option. By hitting Clear Menu, you will clean QuickTime's recent files. When selecting File and Open Recent again, you should have an empty list of your recently viewed files.
Thanks, is working. :)
I follow this command and is working.
I did that too, but be aware that when you right click on the Quick time player in the dock, it still shows all your history there, how to erase and disable this I would like to know.....
