That isn't really true. OS X is based on BSD, which is not "the original UNIX." The original Unix was closed source and was actually quite proprietary.

- TazeTSchnitzel 12y agoBSD is derived from the original UNIX. There is probably code in OS X that ran on PDP-11s once.
- ptx 12y agoNone of the original code is left, though. Mac OS X is based on (for the Unixy bits) FreeBSD and NetBSD, which are based on 4.4BSD-Lite, which was BSD with all the AT&T-derived parts chopped off.
