   <?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>Label</key>
       <string>limit.maxfiles</string>
       <key>ProgramArguments</key>
       <array>
         <string>launchctl</string>
         <string>limit</string>
         <string>maxfiles</string>
         <string>64000</string>
         <string>524288</string>
       </array>
       <key>RunAtLoad</key>
       <true/>
       <key>ServiceIPC</key>
       <false/>
     </dict>
   </plist>

   $ sudo launchctl load -w /Library/LaunchDaemons/limit.maxfiles.plist
