There isn't a good way to do this. launchd jobs are atomic; their services are either all on or all off. You could separate each of your services into a separate launchd job, but even that's a bit tricky. If you're an /agent/ then the job exists in two places: A. it's statically defined by the property list in /Library/LaunchAgents B. each per-user launchd [1] has an in-memory representation of the job Modifying A requires privileges. Modifying B requires privileges for other user's launchd's, but does not require privileges for your launchd. So, if you split your services into separate jobs then you can load and unload those jobs into the current user's launchd context [2] at will. The gotcha being that this only take effect in memory. The next time the user logs out and then logs back in, the settings from A apply.

Since 10.10 there's only one launchd process but I still find it helpful to think in the older terms. [2] Keep in mind that "current user" means "the user in whose context your launchd agent is running" not "currently logged in user". _______________________________________________ launchd-dev mailing list launchd-dev@lists.macosforge.org https://lists.macosforge.org/mailman/listinfo/launchd-dev
