Mac OS X Darwin is the open-source core of Apple's macOS operating system, providing the foundational elements such as the kernel, device drivers, and system libraries. It is based on the XNU (X is Not Unix) kernel, which combines components from both BSD Unix and the Mach microkernel. Darwin serves as the underlying architecture for macOS, facilitating compatibility and performance while allowing developers to access its source code for customization and development purposes. It plays a crucial role in the stability and functionality of the macOS environment.
Mac OS X uses Darwin.
I'm not sure if you mean the foundation of Mac OS X itself, or of the desktop. The desktop is a part of Mac OS X's Finder application which is written by Apple from scratch in Objective-C using the Cocoa framework. Mac OS X itself's core is Darwin, a UNIX operating system based on the open source FreeBSD.
The Darwin kernel of Mac OS X is open source, as are many other parts of the OS. (See links below) but Mac OS X itself is not open source and Apple only allows it to run on Apple hardware.
The second name of Mac OS X v10.4.5 is Mac OS X v10.4 Intel.Mac OS X 10.4 was known as Mac OS X Tiger.
Mac OS X 10.4 (Tiger) needs to be purchased as it is not possible to update from Mac OS X 10.2.8
Mac OS X is an operating system released by Apple Inc. It is designed for Apple branded computers, which is why you will never see a Dell, or an HP computer run Mac OS X. There are only two important versions of Mac OS X, Mac OS X Server, and regular Mac OS X. Mac OS X server was designed for servers, while regular Mac OS X was designed for most computers. The current version of Mac OS X (10.6) is named Snow Leopard.
Yes, it is. Any type of MacBook that comes out now is a Mac OS X. The most recent version of Mac OS X is Mac OS X Lion, coming out soon.
It runs a pared down version of Mac OS X with a FreeBSD sub-system. It also operates over a Darwin Kernel for those who are interested.
Mac OS X is based on UNIX.
The 4 Applications that were released were: 1. iTunes 2. iMovie 3. iPhoto 4. iDVD All of these were created to run on OS 9 until OSX came out. All Mac OSX Releases (in order): -Mac OS X Server 1.0 "Hera" -Mac OS X Public Beta "Kodiak" -Mac OS X 10.0 "Cheetah" -Mac OS X 10.1 "Puma" -Mac OS X 10.2 "Jaguar" -Mac OS X 10.3 "Panther" -Mac OS X 10.4 "Tiger" -Mac OS X 10.5 "Leopard" -Mac OS X 10.6 "Snow Leopard" -Mac OS X 10.7 "Cougar" (still in development, scheduled for 2011 release)
OS X was forked from the FreeBSD 2.x/3.x branch. with kernel mods and the quartz userland. the various OS X releases have corresponding FreeBSD releases. it uses the FreeBSD mach microkernel with os9 compatibility. Darwin is the development builds of OS X versions. the FreeBSD guys backport OS X tech into their OS. OS X is opensource aside from the quartz userland. OS X also includes kernel components from the NeXT step operating system.
Mac OS X can only be installed on Apple hardware so Vmware is unable to support Mac OS X on anything other than a Mac by running, for example, a virtual installation of Mac OS X Server on a standard Mac OS X machine. Conversely Vmware's Fusion allows the running of Windows, and other operating systems, on an Intel Mac running Mac OS X.
