This code has the "kicking" effect I was after for *display sleep*, but has no effect on the screensaver: I can probably get by with just this by disabling the screensaver, but it'd be nice if the screensaver could be "kicked" as well. Any ideas? Shayne It's described in the 10.5 Darwin release notes here: http://developer.apple.com/releasenotes/Darwin/RN-IOKitPowerManagment/index....

Correct - IOPMAssertionTypeNoDisplaySleep, as written today, will not keep the ScreenSaver off. This is a bug & an oversight. You can expect a future release of OS X to also keep the ScreenSaver off when NoDisplaySleep is asserted. IOPMAssertionID assertionID; IOReturn err = IOPMAssertionCreate(kIOPMAssertionTypeNoDisplaySleep, kIOPMAssertionLevelOn, &assertionID); err = IOPMAssertionRelease(assertionID); On Fri, Jul 18, 2008 at 5:49 PM, Ethan Bold <ebold@apple.com> wrote: Check out IOPMAssertionCreate() with type kIOPMAssertionTypeNoDisplaySleep. This is new in 10.5. I need an API call/approach for "kicking" the the display-sleep/screensaver timers, as if the user had moved the mouse or pressed a key. I need a program to be able to wake up the display and/or stop the screensaver, without having the user interact with the mouse or keyboard. (E.g., for an app used in a classroom situation to broadcast a message to a Mac hanging on a wall that happened to be in sleep mode).
