Mac OS X Server gives you everything you need to provide standards-based workgroup and Internet services Pre-emptive multitasking and memory protection, for example, improved the ability of the operating system to run multiple applications simultaneously without their interrupting or corrupting each other. Mac OS X included a number of features intended to make the operating system more stable and reliable than Apple's previous operating systems. On top of this core, Apple designed and developed a number of proprietary closed source components, including the Aqua user interface and the Finder shell. Its core, named Darwin, is an open source, Unix-like operating system, built around the XNU kernel with standard Unix facilities available from the command line interface.

Mac OS X was a radical departure from previous Macintosh operating systems as its underlying code base is completely different from previous versions.

I also became aware that Darwin was released in compiled form here, which may be a useful starting point for hacking your way around things.Mac OS X was a radical departure from previous Macintosh operating systems as its underlying code base is completely different from previous versions. I have no idea if this means the project is alive or not. You couldn't build a working system off Apple's code, but you could pull in some other things and do so if you didn't mind losing much of the Apple UI.Įdit - as of Feb 2013, there appears to be a new release of PureDarwin, which claims fairly major changes. I'd note both projects appear dead, and you would lack many of the desktop components like the desktop and so on.Īs such, well, it's sort of open sourced, but not in the same way as Linux or BSD. The Darwin Kernel (based off BSD) is here - while in theory it's possible to build an OS off it - see OpenDarwin and PureDarwin. Here's all of Apple's open source components. OS X is based off bits of FreeBSD, as well as a micro kernel called L7, and Apple has chosen to keep the source of this open - since they have the option to close it off under the BSD license. None of these are GNU licensed - most BSD variants are BSD licensed, and some versions of Solaris were under the CDDL. There are also still OSes that have a heritage in the original Unix versions - Solaris and some of the BSDs for example. Unix isn't open sourced, and these days it's a certification for a family of OSes that match the Unix common standards. In addition to that, Mac OS X ships with hundreds of open source components from Apache to ZFS, most of which are not owned or maintained by Apple.

WebKit is used by a huge number of browsers.Īnother Apple open source project you may have used even if you don't use Mac OS X is ( (software)), Apple's implementation of Zeroconf.Īpple also owns CUPS, a printing system that is used by a number of operating systems.Īpple also has a number of other open source projects, such as a streaming server, and they contribute to many more open source projects, such as gcc.

One of the most prominent Apple open source projects is probably WebKit, which was originally a fork of KHTML and KJS.

You also ask about other open source parts of Mac OS X:īesides the kernel, What about the various other pieces? The X server? Window Manager? File explorer? etc. Mac OS X's windowing system (called Quartz Compositor) is not open source.

It's Mac OS X's kernel, similar to how Linux is the kernel of a Linux distro. Others have already explained that Darwin is open source.
