When I try to empty my trash I am getting the following message: The operation cant be completed because an unexpected error occurred (error code -8003). I am unable to find info on error code -8003. I believe it has come about because I wanted to make some space on my external hard drive and tried to trash some earlier time machine backups. I did some research on time machine and it is probably the problem. I tried to change my time machine back up disc to see if it would get around the problem but it hasnt. Can someone enlighten me?
