Hey guys, I got curious—what exactly is this macOS thing? I know it's Apple's desktop operating system, but technically, how is it different from the others? Like, how does it stand out from Windows? Does it use a unique kernel, or is it just the interface that's different? Honestly, it's a bit confusing.
What is macOS and how does it work?

macOS and Windows differ most significantly in their underlying kernel systems. While macOS uses the Unix-based BSD kernel (Darwin), Windows relies on its own monolithic kernel (NT). This means macOS adheres to Unix standards, allowing direct use of `bash`/`zsh` in the terminal and running Unix commands natively.
When it comes to the interface, macOS offers a distinct design aesthetic and a tightly integrated ecosystem (syncing with Apple devices, AirDrop, Continuity, etc.), which sets it apart from Windows. However, since both run on Unix/NT kernels, their core infrastructures are somewhat similar. For instance, both use comparable file systems (NTFS vs. APFS) and process management. Ultimately, the real differences lie in user experience and the depth of their respective ecosystems.
macOS uses Apple's own BSD-based Unix-like kernel (XNU), but unlike Windows, which is kernel-level, macOS is actually a system that integrates Mach microkernel with BSD components. In terms of interface, you see Apple's custom design, like the Dock and menu bar, which looks very different from Windows. Well, you can access Unix commands via the terminal, which, of course, doesn't exist in Windows.
