Thanks for the clarification. These types of details may not be obvious to the average OS X user who tries to have a basic knowledge of the OS. Particularly when Apple puts statements such as the one below on their page for OS X:






Referred to by its code name, Jaguar, Mac OS X v10.2 is a different breed of operating system. Jaguar combines the rock-solid reliability of UNIX with the ease of use of Macintosh. This version of Mac OS X is as innovative as the computers that run it. And whether you?re a Mac user who?s upgrading, a Windows user who?s looking at switching to the Mac or a UNIX user who loves the idea of using key applications like Microsoft Office on top of a state-of-the art BSD UNIX implementation, this is the OS for you.
