Windowsでは、GetProcessMemoryInfoを呼び出すことでピークメモリ使用量を取得できます

function TProcess.Peek: Cardinal;
var
  PMC: PPROCESS_MEMORY_COUNTERS;
  PMCSize: Cardinal;
begin
  PMCSize := SizeOf(PROCESS_MEMORY_COUNTERS);
  GetMem(PMC, PMCSize);
  try
    PMC^.cb := PMCSize;
    if GetProcessMemoryInfo(FHandle, PMC, PMCSize) then
      Exit(PMC^.PeakWorkingSetSize)
    else
      Exit(0);
  finally
    FreeMem(PMC);
  end;
end;

これを行うのに相当するMacOSは何ですか？
