Introduction to Mac OS

---------------------------------------------------

The Mac OS Operating System of Apple Computer is developed based on "BSD" and compatible with POSIX.

UNIX is an excellent operating system, Linux is a unix variant, and BSD is also a unix variant.

Unix has four major BSD variants: FreeBSD, OpenBSD, NetBSD, and Mac OS X.

The Mac OS Operating System is based on the FreeBSD kernel. The tool software and environment that can be used are basically the same as the real FreeBSD environment.

The BSD Core Used in Mac OS is known as Darwin (Darwin ).
