title: How to change kernel settings, shared memory configuration?
body: <p>I'm trying to install PostgreSQL and I need to allow for more shared memory configuration. Following the PostgreSQL documentation here:</p>
  
  <p><a href="http://www.postgresql.org/docs/8.2/static/kernel-resources.html" rel="nofollow">http://www.postgresql.org/docs/8.2/static/kernel-resources.html</a></p>
  
  <p>I just need to find a file called <code>/etc/sysctl.conf</code>, but I'm having a hard time.</p>
  
  <p>But I guess you could say I'm new with computers, and I have no idea how to locate this file on my Mac, and google isn't helping. Any and all help is appreciated.</p>
