Capture power button press on MacOs High Sierra?
Hello everyone!

I'm developing a MacOs Application in python and I'm having some issues trying to find information related to the power button pressed event. I know that in Ubuntu 14.04 you can find information about it on the acpi folders, but I realized that here in Mac that process is supposedly managed by powerd, I was looking thru the dmesg and console logs looking for something that changes when a restart is done automatically or if the computer couldn't restart itself and had to be powered on by the button.

Let me explain a little more.

In the application, I have a config file where I keep record of how many restarts have been done on the Mac by another application developed by Apple called RestartX. When it hits 10 restarts it will stop with an automation script on Sikuli. The thing is that when the test fails, the computer MUST be turned on by the user, and the RestartX app doesn't record if the test fails as it registers that operation as a Restart (which adds 1 to the app restart counter) and not as a PowerOn event.

If someone with more programming experience could tell me where to catch this kind of events apart from dmesg or how to tell which event in dmesg is related to powerEvents I will be very grateful.

glutspaceballbuttonfunc

glutSpaceballButtonFunc(3GLUT)					       GLUT					    glutSpaceballButtonFunc(3GLUT)

NAME

       glutSpaceballButtonFunc - sets the Spaceball button callback for the current window.

SYNTAX

       void glutSpaceballButtonFunc(void (*func)(int button, int state));

ARGUMENTS

       func	 The new spaceball button callback function.

DESCRIPTION

       glutSpaceballButtonFunc	sets  the  Spaceball  button callback for the current window. The Spaceball button callback for a window is called
       when the window has Spaceball input focus (normally, when the mouse is in the window) and the user generates Spaceball button presses.  The
       button  parameter  will	be  the  button number (starting at one). The number of available Spaceball buttons can be determined with glutDe-
       viceGet(GLUT_NUM_SPACEBALL_BUTTONS). The state is either GLUT_UP or GLUT_DOWN indicating whether the callback was due to a release or press
       respectively.

       Registering  a  Spaceball button callback when a Spaceball device is not available is ineffectual and not an error. In this case, no Space-
       ball button callbacks will be generated.

       Passing NULL to glutSpaceballButtonFunc disables the generation of Spaceball button callbacks. When a new window is created,  no  Spaceball
       button callback is initially registered.
