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.

glutbuttonboxfunc

glutButtonBoxFunc(3GLUT)					       GLUT						  glutButtonBoxFunc(3GLUT)

NAME

       glutButtonBoxFunc - sets the dial & button box button callback for the current window.

SYNTAX

       #include <GLUT/glut.h>

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

ARGUMENTS

       func	 The new button box callback function.

DESCRIPTION

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

       Registering  a  dial & button box button callback when a dial & button box device is not available is ineffectual and not an error. In this
       case, no dial & button box button callbacks will be generated.

       Passing NULL to glutButtonBoxFunc disables the generation of dial & button box button callbacks. When a new window is created,  no  dial  &
       button box button callback is initially registered.
