+### Start tinc automatically on system boot
+
+[launchd](http://en.wikipedia.org/wiki/Launchd) is a system for monitoring services and make sure services are started if certain conditions are met. This system is available on OS X 10.5 and later versions.
+
+To use launchd, you have to create a property-list file for tinc and put it under /Library/LaunchDaemons/
+
+The following example is a plist file for the tinc network name: myvpn
+
+*/Library/LaunchDaemons/myvpn.tinc.plist*:
+
+    <?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>
+       <true/>
+       <key>Label</key>
+       <string>tinc.myvpn</string>
+       <key>ProgramArguments</key>
+       <array>
+               <string>/opt/local/tinc/sbin/tincd</string>
+               <string>-n</string>
+               <string>myvpn</string>
+               <string>-D</string>
+       </array>
+    </dict>
+    </plist>
+
+This will configure tincd to start the myvpn configuration in the foreground (-D). If tincd is started as background daemon, launchd will not function correctly with tinc. Launchd will directly start tincd if this file is found. The <key>KeepAlive</key> element will ensure that tincd is always running, and to be restarted if it stops. To stop tincd, use the *launchctl* command. Some commands to remember are:
+
+    launchctl unload -w /Library/LaunchDaemons/myvpn.tinc.plist
+
+This adds a *disabled* key to the file and stops tincd. The disabled key ensure that launchd will not start tincd anymore. The inverse operation is:
+
+    launchctl load -w /Library/LaunchDaemons/myvpn.tinc.plist
+
+This removes the *disabled* key from the file and starts tincd.
+
+To stop tinc:
+
+    launchctl stop tinc.myvpn
+
+To list all services monitored by launchd:
+
+    launchctl list
+
+If tinc has been configured with launchd, you will see tinc.myvpn listed with a process id.
