====== LaunchDaemons (and LaunchAgents) ======

The difference between a LaunchDaemon and a LaunchAgent is that the agent will run as any user that logs in through loginwindow, while the agent can launch even before that as the root (or another specified) user.

==== Example LaunchDaemon and how to activate ====
  - Create a plist like this \\ <code xml><?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>KeepAlive</key>
    <false/>
    <key>Label</key>
    <string>net.wgratz.cpunap</string>
    <key>ProgramArguments</key>
    <array>
      <string>hwprefs</string>
      <string>cpu_nap=1</string>
    </array>
    <key>RunAtLoad</key>
    <true/>
    <key>KeepAlive</key>
    <true/>
    <key>LaunchOnlyOnce</key>
    <true/>
  </dict>
</plist></code>
  - Move it to ''/Library/LaunchDaemons''
  - Load it by executing ''sudo launchctl load -w /Library/LaunchAgents/net.wgratz.cpunap.plist''
  - Start it by executing ''sudo launchctl start net.wgratz.cpunap''
