OSX Mountain Lion (ML) has an idle sleep policy that requires apps to set sleep assertions if they want to prevent sleep after the period set in Energy Saver - see for example http://arstechnica.com/apple/2012/07/os-x-10-8/18/. This means that utilities I relied on under Lion - Caffeine and ReallyPreventStandby plugin for LMS no longer work.
There is a new command line utility in ML that might give some pointers to a way forward: caffeinate prevent the system from sleeping on behalf of a utility This allows you to either directly prevent your Mac from falling asleep for a specific period of time (e.g. an hour): caffeinate -u -t 3600 or allows a command to run for a prolonged period without the automatic (and, since 10.8, rather aggressive) sleep function kicking in caffeinate -s any-long-running-command -with arguments The source of caffeinated seems to be here: http://opensource.apple.com/source/PowerManagement/PowerManagement-271.25.8/ Has anyone else had sleep issues under ML running LMS (I am running 7.7.2)? Does anyone who knows the system better than me have any suggestions for a way forward? Seems like these new assertions could finally give a reliable solution to LMS sleep issues under OSX if they could be incorporated somehow. I do not think it will work just for ReallyPreventStandby to call caffeinate as the command just hangs until interrupted if called as caffeinate -i. All help much appreciated. ------------------------------------------------------------------------ nonnoroger's Profile: http://forums.slimdevices.com/member.php?userid=35581 View this thread: http://forums.slimdevices.com/showthread.php?t=95980
