Mach-O

Mach-O (Mach Object) is a file format used by macOS and iOS to organize and store programs and their components. It acts like a blueprint for how the computer should load and run software, containing information about code, data, and libraries. Think of it as a detailed instruction manual that guides the operating system in assembling and executing an application efficiently. Mach-O files are optimized for Apple's systems, enabling smooth software operation, development, and updates on Mac and iOS devices.
