The underlying open-source core kernel of MacOS is called "darwin" but the Originally Answered: What's the difference between UNIX, Mac, Linux, Windows?. Geekofweek: "Long time Linux user who switched to the Mac full Geralddarden : "Long time Linux user and currently employed as a Linux/Unix admin I can . gave me a preview of the web page on the other end of the link. As twxwikinger said, the major difference between Mac OS X and Ubuntu being Linux based, which are two separate branches off of UNIX.

I thought they shared no code? Windows NT was developed to be a "real" modern, preemptive, multi-user, multi-tasking secure operating system. A kernel provides a platform for programs to run, in the case of Unix, it allows multiple programs to run on a single computer and multiple users to access it.

What is the Difference Between the macOS and Linux Kernels

A kernel runs no programs on its own, these must be separately developed and provided. An API is a standard way for programs to talk to the kernel. It's part of the kernel.

An operating system is a kernel plus common utility programs to manage and administrate the system. Common utility programs for UNIX include basic programs that manage services and logins inita shell that allows you enter commands sh, bashand basic file management commands such as cp, ls, mv, etc.

Debian is a Linux distribution. It started in and is among the oldest distributions.

Linux distributions generally provide: It's different from Windows where traditionally software has been distributed on CDs and years go by between versions and updates. And to quote the same page: Darwin technology is based on BSD, Mach 3. Based on everything above we can confidently say, OS X is not a distribution, in the sense of Linux distribution.

What is the Difference Between the macOS and Linux Kernels - It's FOSS

Similarly, other mentioned OSs are POSIX compliant and are certified Unix systems, but again they differ in kernels and variations on underlying system calls which is why there exist books on Solaris system programming and it's a worthy subject in its own right. Therefore, they aren't distributions in the sense Linux distributions are - a common core with variations on utilities. In case of Linux, you see books on Linux system programming or Linux kernel programming, not system programming specific to distribution, because there's nothing system-specific about a particular distribution.

Confirmation of what we see here can be found in official documentation. In other words, they are based on the same foundation, but they don't share exactly same one in the sense Linux distros share the kernel. Considerations Note that the word distribution appears to be mostly used when referencing operating systems which have the Linux kernel at its core.

To quote this answer on our site in response to the question whether different BSD versions use same kernels: No, although there are similarities due to the historic forks.

Each project evolved separately. They are not distributions in the sense of Linux distributions. Consider the copyright notice from this document: The true problem is that you the reader and I have way too much time to argue about the topic which lawyers should be arguing about. Maybe we should be like Linux Torvalds and use terminology and OSs that just allows us to move on with the life and do the things we honestly care about and are supposed to care about.
