Not so far ago, I was lost on the net, and I found a piece of code to simulate a Kernel Panic in the osxbook site.
Well, and as we are Mac Users, we don’t see this kind of thing very often [TROLL]Not like on Windows[/TROLL], so I decided to share this little piece of code

#include <sys/types.h>
#include <sys/sysctl.h>

#define KERN_PANICINFO_TEST (KERN_PANICINFO_IMAGE + 2)

int main(void)
{
    size_t oldnewlen = 0;
    int mib[3] = { CTL_KERN, KERN_PANICINFO, KERN_PANICINFO_TEST };
    return sysctl(mib, 3, NULL, (void*)&oldnewlen, NULL, oldnewlen);
}

gcc panic_test.c -o panic_test
sudo ./panic_test

Result :

You have to be root to execute the program, because of sysctl()

In this site there is another post to show how you can change your panic screen, if you don’t know what to do…
