i have app creates time lapse movies on os x webcams available through url. have had lots of users complaining recordings dropping tons of frames. have isolated problem yosemite disconnecting wifi when screen locks. there way let system know important app keeps network connection? annoying tell users go in , disable screen locking use app.

the nsactivityuserinitiated option should enough.

there's nsactivityidledisplaysleepdisabled.
