In macOS 10.12's ServiceManagement/ServiceManagement.h the following functions are marked as deprecated since macOS 10.10:

- SMJobSubmit

- SMJobRemove

- SMCopyAllJobDictionaries

The header mentions replacements will be provided by libxpc. Are replacements available or on the way?

I have a system wide daemon that would like to programmatically launch a process in a graphical user session. At the moment, our LaunchAgents managed helper process is always running. Ideally, it would be good to launch and exit the helper on-demand.

I believe this can now be done with `launchctl bootstrap|bootout gui/<uid>` on the command line. Should the daemon call out to the launchctl tool?

Kind regards,

Graham
