The Mac OS nanokernel is a core component of the operating system architecture used in Apple's macOS and is a descendant of the Mach microkernel. The term "nanokernel" often refers to a lightweight kernel that handles the most fundamental tasks required by the operating system while relying on other components, like device drivers and higher-level services, to manage additional functionality.
