macOS, which is a Unix system, uses daemons. A daemon is a computer program that runs as a background process, rather than being under the direct control of an interactive user.
macOS, which is a Unix system, uses daemons. A daemon is a computer program that runs as a background process, rather than being under the direct control of an interactive user.
Traditionally, the process names of a daemon end with the letter d, for clarification that the process is, in fact, a daemon, and for differentiation between a daemon and a normal computer program.
For example, syslogd is the daemon that implements the system logging facility, and sshd is a daemon that serves incoming SSH connections.
