Why can't I connect wirelessly to my product using EMP NS Connection on OS X 10.5.x?

• You need to install the latest version of EMP NS Connection on your computer. Download it from the Downloads tab for your product and follow the instructions to install it.
  
  Note: Because of the built-in firewall, you'll see the message Set access for specific services and applications when you use NS Connection for the first time on a MAC with OS X 10.5. Be sure to select Allow incoming connections when you see this message. (If you select Allow only essential service, NS Connection will not work properly.)
