Talk:OS X/@comment-67.172.161.83-20150707085335

Whoops; refering to "A Practical Guide to Linux Commands, Editors, and Shell Programming" 3rd edition, by Mark G. Sobell, page 2:

"OS X runs the Mach kernel, which was developed at Carnegie Mellon University (CMU) and is free softwware. ...

Much of the Mac OS X software is open source: the Mac OS X kernel is based on Mach and FreeBSD code, utilities come from BSD and the GNU project, and system programs come mostly from BSD code..."

Sorry for the mistatement.
