In Energy Saver settings (System Preferences -> Hardware section) the Mac is set to sleep after 15 minutes, but nothing happens.
Mac drains battery and automatically turns off when battery is low.
If I type
pmset -g assertions in terminal, I get this:
3/31/14 5:46:52 AM EDT Assertion status system-wide: PreventUserIdleDisplaySleep 0 PreventSystemSleep 0 PreventUserIdleSystemSleep 1 InternalPreventDisplaySleep 0 ExternalMedia 0 UserIsActive 0 ApplePushServiceTask 0 BackgroundTask 0 Listed by owning process: pid 251(coreaudiod): [0x0000000100000d01] 00:17:27 NoIdleSleepAssertion named: "com.apple.audio.'AppleHDAEngineOutput:1B,0,1,1:0'.noidlesleep" pid 251(coreaudiod): [0x0000000100000929] 01:11:47 NoIdleSleepAssertion named: "com.apple.audio.'BoomEngine:0'.noidlesleep" pid 269(helpd): [0x0000000c00000159] 02:37:33 BackgroundTask named: "com.apple.helpd.sdmbuilding" Kernel Assertions: None
How should I read this? Why
PreventUserIdleSystemSleep is set to one?
How I can set up Mac go to sleep after certain time of inactivity?
