Again, though, isn't that intentional? If it wasn't, what would stop someone from, for example, stealing a Time Machine HDD and then having access to all the files on it? It's one thing to steal the origin machine but I was under the impression that TM is specifically designed not to allow access from other user accounts unless you know the credentials for the original account from which the backups are created. Is that not accurate? That seems like a giant security hole if it's not...
