How to get process serial number of current running process
<p>In OS X 10.9 and below, we can get the process serial number of the current running process with:</p>

<pre><code>ProcessSerialNumber pen;
GetCurrentProcess( &amp;psn );
</code></pre>

<p>However, GetCurrentProcess() is now deprecated and I'm unsure how to find a process' serial number with NSRunningApplication.</p>
