Mac OS is a graphical operating system developed by Apple for running on Macintosh computers. It was designed only for Apple hardware. Mac OS organizes and manages files through a file management system that tracks file locations in memory and hardware. It allows users to create, open, delete, rename, copy and perform other functions on files. File names include an extension to indicate the file type so the OS knows which program to use to open it. The full file path provides the absolute location of a file including the filename and extension.
