![]() ![]() The software ecosystem and game support for both have evolved over the years, which we will discuss later in this article. Probably a decade back, we could say that both Linux/macOS offered fewer applications. I can’t think of anything else similar between the two. The default shell can be different, but you can always change it as per your preferences. So, what do we have in common here?īoth give access to Unix commands, bash/zsh, and other shells. MacOS utilizes Unix components, and Linux was built as an alternative to Unix. A monolithic kernel is responsible for managing the CPU, memory, inter-process communication, device drivers, file system, and system server calls. While the macOS kernel combines the feature of a microkernel ( Mach)) and a monolithic kernel ( BSD), Linux is solely a monolithic kernel. The Mach part is responsible for low-level work, such as multitasking, protected memory, virtual memory management, kernel debugging support, and console I/O. The BSD subsystem part of the code is “typically implemented as user-space servers in microkernel systems”. The acronym stands for “XNU is Not Unix.” According to Apple’s Github page, XNU is “a hybrid kernel combining the Mach kernel developed at Carnegie Mellon University with components from FreeBSD and C++ API for writing drivers”. The macOS kernel is officially known as XNU. There are hundreds of Linux-based operating systems called distributions.įor simplicity, we tend to address it as Linux OS instead of a specific Linux distribution. Linux is not an operating system but needs different components like desktop environments to form an operating system. On the contrary, Linux (the kernel) was built as a free and open-source replacement for Unix. This is why macOS has a combination of Unix components along with Apple’s proprietary technologies. Apple later acquired NeXT and brought back Steve onboard as part of the deal, making NeXTSTEP OS the base for macOS. While it got some attention, it wasn’t a big success. ![]() Technically, it was based on the Mach Kernel and the UNIX-derived BSD.īack then, a NeXTSTEP operating system was created to power the devices/computers built by NeXT. The foundation of it was built by Steve Jobs’s NeXT computer company when he wasn’t at Apple. ![]()
