Mac OS X is an inherently multi-user operating system, even if only one person ever uses a particular computer. Each user has an account — and in addition, there are numerous built-in accounts that aren't normally visible to users. This chapter begins with an overview of what accounts have to do with security. I then describe what accounts are, how to configure them, and how they relate to the pervasive notion of permissions.
