macOS About This Mac

[john903]

How do obtain the values found in About This Mac -> More Info... such as Model Name or Processor Name in a carbon application?

I've never written a Carbon app, but I seem to remember reading somewhere that you can launch Apple System Profiler, and get the information via Apple events.
I can't help you out more myself, but it might give you a new direction for google searches.

Use sysctl APIs:

#include <stdio.h>
#include <stdlib.h>
#include <sys/sysctl.h>

int main() {
	int hertz;
	size_t size = sizeof(int);
	int mib[2] = {CTL_HW, HW_CPU_FREQ};
	
	sysctl(mib, 2, &hertz, &size, NULL, 0);
	printf("%d\n", hertz);
	return EXIT_SUCCESS;
}

I'm still digging through the output, but did a ktrace on SystemProfiler. So far this file:
"/System/Library/SystemProfiler/SPPlatformReporter.spreporter/Contents/Resources/SPMachineTypes.plist"
is where the machine descriptions come from. Still trying to see where it gets the key. ktrace output might not be enough, but I was thinking it might point to the framework or frameworks that are used.

Also got the output of Strings from the SPPlatformReporter binary, some method and property names in there, it looks like. It might at least help your googling:
