Then they took Darwin and added their own GUI (used to be called Aqua) and that is MacOSX. Bear in mind that the MacOS X gui does not translate directly into UNIX. For example, you can load MacOS System 7 files with a separate resource and data fork onto MacOSX. The MacOS X gui handles a lot of this kind of stuff. Apple also doesen't use the UNIX security model. As near as I can tell their core security model is an ACL model not a user/group model. Once again this is something that's handled elsewhere. > With this being said, then does anyone have any experience with the > stability and performance? > > My guess is that if it is really based upon FreeBSD then the performance > should be pretty good from my readings about FreeBSD compared to other > operating systems. > Mac OS X is easily more stable than FreeBSD simply because it can only be run on specific hardware that Apple sells. As a result the developers always know exactly what their enviornment is going to be like. As for performance, what performance metric are you looking at? The biggest problem with MacOS X is that a lot of UNIX software that runs on FreeBSD and such, is not ported to MacOSX, and it's very difficult to compile on MacOSX.
