MacOS – get sleep time on Mac OS X (and other energy-saving settings)

pmset -g | grep "^[ ]*sleep" | awk'{ print $2 }'

/Library/Preferences/SystemConfiguration/com. apple.PowerManagement.plist

NSString *powerMgt = @"/Library/Preferences/SystemConfiguration/ com.apple.PowerManagement.plist";
NSDictionary *power = [NSDictionary dictionaryWithContentsOfFile:powerMgt];
// for example the sleep time on AC power
NSNumber *sleepyTime = [[[power objectForKey:@"Custom Profile"] objectForKey:@"AC Power"] objectForKey:@"System Sleep Timer"];

{
 ActivePowerProfiles = {
 "AC Power" = "-1";
 "Battery Power" = "-1";
 };
 " Custom Profile" = {
 "AC Power" = {
 "Disk Sleep Timer" = 10;
 "Display Sleep Timer" = 10;
 "Display Sleep Uses Dim" = 1;
 GPUSwitch = 2;
 "Hibernate File" = "/var/vm/sleepimage";
 "Hibernate Mode" = 3;
 "Mobile Motion Module" = 1 ;
 PrioritizeNetworkReachabilityOverSleep = 0;

I want to programmatically get energy saving in System Preferences on Mac OS X Settings, especially the “display sleep” or “computer sleep” settings for the small app I’m writing.

I know you can retrieve the sleep settings, for example, using the command line of this SO answer

pmset -g | grep "^[ ]*sleep" | awk'{ print $2 }'

Print 60 (my correct sleep time) , But I prefer to use the native API to get these settings. Unfortunately, my googling so far did not find anything useful. NSUserDefaults is the closest I got, but I can’t see how to use it Get the settings I am after.

Can anyone help?

Yes, it has been more than 4 years since I asked this question… It is not clear what language the code requires. Use Objective-C.

< /p>

Power saving preferences can be found in the following locations:

/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist

In the Mac application, we can now use:

NSString *powerMgt = @"/Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist";
NSDictionary *power = [NSDictionary dictionaryWithContentsOfFile:powerMgt];
// for example the sleep time on AC power
NSNumber *sleepyTime = [[[power objectForKey:@"Custom Profile"] objectForKey:@" AC Power"] objectForKey:@"System Sleep Timer"];

Use a dictionary to look like:

{
 ActivePowerProfiles = {< br /> "AC Power" = "-1";
 "Battery Power" = "-1";
 };
 "Custom Profile" = {
 "AC Power "= {
 "Disk Sleep Timer" = 10;
 "Display Sleep Timer" = 10;
 "Display Sleep Uses Dim" = 1;
 GPUSwitch = 2;
 "Hibern ate File" = "/var/vm/sleepimage";
 "Hibernate Mode" = 3;
 "Mobile Motion Module" = 1;
 PrioritizeNetworkReachabilityOverSleep = 0;
 "Standby Delay" = 4200;
 "Standby Enabled" = 0;
 "System Sleep Timer" = 0;
 TTYSPreventSleep = 1;
 "Wake On AC Change" = 0;< br /> "Wake On Clamshell Open" = 1;
 "Wake On LAN" = 1;
 };
 "Battery Power" = {
 "Disk Sleep Timer" = 10;
 "Display Sleep Timer" = 10;
 "Display Sleep Uses Dim" = 1;
 GPUSwitch = 2;
 "Hibernate File" = "/var/vm/ sleepimage";
 "Hibernate Mode" = 3;
 "Mobile Motion Module" = 1;
 ReduceBrightness = 1;
 "Standby Delay" = 4200;
 " Standby Enabled" = 0;
 "System Sleep Timer" = 15;
 TTYSPreventSleep = 1;
 "Wake On AC Change" = 0;
 "Wake On Clamshell Open" = 1;
 };
 };
}
