MacOS passes this except for the si_status test. MacOS uses a signed int there. I’m not
sure what the standard says.

Given that MacOS X is not POSIX compliant, I would call it a UNIX-alike.
Note that passing the certification tests unfortunately does not grant
POSIX compliance :-(
Try e.g. this program on Mac OS X:
#include <stdlib.h>
#include <unistd.h>
#include <sys/wait.h>
#include <stdio.h>
/*
* Non-standard compliant platforms may need

int
main()
{
siginfo_t si;
pid_t pid;
int ret;
if ((pid = fork()) < 0)
exit(1);
if (pid == 0) {
_exit(1234567890);
}
ret = waitid(P_PID, pid, &si, WEXITED);
printf("ret: %d si_pid: %ld si_status: %d si_code: %d\n",
ret,
(long) si.si_pid, si.si_status, si.si_code);
if (pid != si.si_pid)
printf("si_pid in struct siginfo should be %ld but is %ld\n",
(long) pid, (long) si.si_pid);
if (si.si_status != 1234567890)
printf("si_status in struct siginfo should be %d (0x%x) but is %d
(0x%x)\n",
1234567890, 1234567890, si.si_status, si.si_status);
if (si.si_code != CLD_EXITED)
printf("si_code in struct siginfo should be %d (0x%x) but is %d (0x%x)\n",
CLD_EXITED, CLD_EXITED, si.si_code, si.si_code);
if (CLD_EXITED != 1)
printf("CLD_EXITED is %d on this platform\n", CLD_EXITED);
return (0);
