How can I distinguish a service form a process in Activity Monitor?

Is there a way to determine if an entry listed in Activity Monitor is a service (daemon) or a process (application)?



Examples:




  • Firefox (application)

  • com.apple.audio.SandboxHelper (daemon?)


Is there a good definition of what these terms (that I'm using loosely) mean in OS X?






macos activity-monitor

    What do you want to do, once you know the difference? Services are often essential to the parent application process.

    Please can you ask a new question for Does the application need to be built in specific way (e.g. no UI, implement certain interfaces) so it can be used as a service?` Ask Different works best when each question is asked separately. Feel free to refer to other questions in your new question.

All Processes, Hierarchically



Activity Monitor can show the process hierarchy:



Activity Monitor.app > View (menu) > All Processes, Hierarchically



The grouping shows those processes launched by another process. Typically child-process will be services of the parent. On macOS many of these child processes will be XPC instances.



Services are Processes



On macOS, daemons are processes and services are processes. In your example, com.apple.audio.SandboxHelper, this is an XPC service.

    This would make a great new question. The root process in macOS is launchd and Apple have decided to put almost every process launch through it. I suspect it has many benefits but those can be discussed in a new question.

Technically speaking, anything that gets loaded and executed is a process; so a service is a process.



A service is a nuanced definition of something that gets loaded to provide a service like DHCP or DNS.



A alternative way to sum this up is all services are processes, but not all processes are services. An example would be Firefox, it's a process, but not a service - it's an application.
