Linux is known to be an operating system that can be installed on your PC, while Macintosh happens to be a complete package that includes both software and hardware. A major difference between the Macintosh operating system and Linux is in their licensing. Linux is known as open-source software, whereas the Macintosh operating system is proprietary.
The Linux distribution can be downloaded on any software that is compatible with it without spending any amount of money. The Mac OS, on the other hand, can only be bought together with the Macintosh package, and be rest assured that part of the money you are paying is for the operating system.
The Mac can easily be used without any complex knowledge. Just plug your package to your socket outlet, and you can start to operate it with the basic knowledge of computer operation. On the other hand, Linux needs some sort of configuration and installation of packages to start using it.
