What is the macOS kernel?

The heart of the Mac OS X is the XNU kernel. The kernel refers to the part of an operating system that loads first. It controls and monitors hardware resources like memory, CPU processor allocation and disk drives.

Is Mac based on FreeBSD?

But OSX is built in part on an open source Unix derivative called FreeBSD. And until recently, FreeBSD’s co-founder Jordan Hubbard served as director of Unix technology at Apple. It was a better fit: Mac OS X shares conceptual roots with Linux, but it shares honest-to-goodness code with FreeBSD.

What does the kernel mean in Mac OS X?

The kernel refers to the part of an operating system that loads first. It controls and monitors hardware resources like memory, CPU processor allocation and disk drives. The XNU kernel includes code from an old computer architecture system called Mach. Mach is a product of Carnegie Mellon University and has been around since the 1980s.

Is the Mach kernel part of the kernel environment?

In OS X, however, the kernel environment contains much more than the Mach kernel itself. The OS X kernel environment includes the Mach kernel, BSD, the I/O Kit, file systems, and networking components. These are often referred to collectively as the kernel.

Is the OS X kernel an open source project?
