cannot delete files
Hello
I have been using Mac since 2 years ago. Recently I ran into some weird problems with my macbook pro , Mountain Lion OS. When I delete files from the Finder, it asks for password, pretends that it moves files into the Trash (with the noise). And the files are still there. I have read several recommendations about permission of admin needs to be changed and repair disk and restart the computer...nothing has worked so far. 😟 . Can anyone help to solve this problem?
Thank you in advance.
MacBook Pro (Retina, Mid 2012), OS X Mountain Lion (10.8.3)
