Comment Re:Apple uses and supports FreeBSD (Score 1) 90
Apple's macOS. Apple contributes code and employs some FreeBSD developers.
Its a little more complex. Apple does derive some of FreeBSDs userland and some services. However its a myth that the kernel is a modified FreeBS. Its a modified Mach microkernel, XNU (technically actually a hybrid, like most real world microkernels, that has a small amount of non core kernel in ring zero for performance reasons, that has some services that have FreeBSD derived code in it, namely the network stack, process model and IOKit.
