FreeBSD Not too long ago, Apple open sourced its Grand Central Dispatch library, which aids in developing multithreaded code. It was suggested that it could be ported to other platforms, and the FreeBSD team has done exactly that. They have also done a lot of work related to getting GCD to work in a POSIX environment.

Mac OS X has also a different interface than POSIX to the system internals: Mach. If I remember the source and docs of GCD correctly it uses those Mach interfaces. This example says nothing about if Mac OS X is POSIX compliant, it just indicates there is a different interface.

I guess that almost no OS is 100% posix compliant, not even FreeBSD or Linux (but I'm not sure about that). Almost every Unix OS is to a certain degree Posix compliant, even Mac OS X.
