liujianwei Posted October 29, 2013 Share Posted October 29, 2013 'm using mavericks On both 'System Preferences' > 'Energy Saver' > 'Display Sleep' does no longer work reliably (compared with Mountain Lion). When I close all apps and set the Display Sleep time to "1 min." (minimum) and wait... in the majority of cases the display stays ON! What's the reason? How can this be fixed? Many thanks!

nyolc8 Posted October 29, 2013 Share Posted October 29, 2013 When it goes to display sleep but the display itself stays on, is the mouse cursor disappears, and the screen freezes (test with playing a video)? Link to comment Share on other sites More sharing options...
