I have a password protected disk image that mounts, but when I mount it there's a lock that shows up in the icon and I can't access the contents- "The folder "Disk Image" could not be opened because you do not have sufficient access privileges." When I Get Info it has my account, (unknown) and "everyone" all set with custom access. Ignoring ownership does nothing, and I can't change the permissions. I can't get at it via Terminal, and sudo chmod doesn't work either (which I don't quite understand...). How can I get at the contents of this disk image?
