If you'd like to simulate network crappiness on OS X, you can use the Network Link Conditioner from Apple themselves: http://nshipster.com/network-link-conditioner/ http://nshipster.com/network-link-conditioner/ I was very impressed with its feature-set (for what it is). On our team, we use it to see how our iOS app will react to severe network problems (via testing in the simulator, mostly, though it's also available on iOS devices themselves as explained in the above article).
