Simulate bad network connection for multiplayer or online games on Mac
When you are developing multiplayer or online games, you sometimes need to emulate the real network conditions that are out there: 3G, DSL, or very bad connections. Fortunately, this is very easy to do on your mac.
Just open XCODE, and from its menu: Xcode > Open Developer Tool > More Developer Tools… Login to your apple account, and then download the hardware IO tools. After installing it, execute the Network Link conditioner, and it will be installed into your system preferences section. Then just run it and you are ready to go!
