I would disagree that apple and open source are not friends, there are plenty of open source apps on apple store, apple itself has a bunch of stuff made open source on the previous years, including os kernels, programing languages, webkits, development tools... Apple does indeed has some license requirements that are not compatible with some open source licenses, but that does not make apple and open source enemies.
Mac and Open Source are not best friends. But there are Mac compiled versions out there.
Someone made the friendship happened here :
