Questions tagged [launch-daemon]

On Apple macOS, a launch daemon is a system service which runs as a regular process, but independently of login/windowing sessions in the background, and frequently with root/administrator privileges. This is in contrast to launch agents, which are linked to sessions, and to system extensions, which run in special sandboxed environments and runtimes.
