Still, you might be interested in customizing the first thing you see when you turn on your Apple laptop or desktop. ~ I don't want to hardcode 1minute, since obviously it should regardless of what your screensaver time setting is.You probably don't spend a lot of time on your Mac's lock screen page, and for good reason - it's only meant for unlocking and getting in to your computer. When watching a YouTube Video, 1minute after the video ends, is when the screensaver will turn on, regardless of how long the youtube video is, even if it's e.g. Is there no way to do this in modern versions of MacOSX? Chromium currently exhibits the exact feature that I desire. But, if no frame gets rendered in a 1minute interval, the screensaver should be displayed. Because, the timer should be reset every single time a framebuffer gets rendered. I need to simply reset the 1min screensaver timer. Often it's said that IOPMAssertionRelease should only be called after the screen no longer wants to be held awake, but I don't think that's the functionality I need.
When I set my screensaver to 1minute, but run the above code in a loop at 60FPS, the screensaver still turns on eventually. However, neither of these in my testing appear to actually reset the MacOSX Screensaver timer. IOPMAssertionRelease(power_assertion_id) Or IOReturn result = IOPMAssertionCreateWithName( KIOPMUserActiveLocal, &activity_assertion_id) IOReturn r = IOPMAssertionDeclareUserActivity(CFSTR("FractalUserActivity"), In modern versions of MacOSX, the most commonly recommended solution is: static IOPMAssertionID activity_assertion_id = kIOPMNullAssertionID In older versions of MacOSX, one would use UpdateSystemActivity(UsrActivity)
