macOS Overview

macOS is a Unix-based operating system developed by Apple Inc. for its Mac hardware lineup. It combines a polished graphical user interface with a stable Unix foundation, making it popular among developers and general users.

The primary advantage of macOS is its stability, ease of use, and strong ecosystem integration. However, it is limited to Apple hardware and offers less low-level system control compared to Linux distributions.
