They were running Snow Leopard and the current game client needs Lion or better.

But almost immediately I was forced to revoke this pat, because he still couldn’t log in. The launcher would start, the client would load, his

username and password were both accepted, but the game would freeze for 30 seconds or so and then ask him to choose an alternative server – implying that his default one was full. This definitely wasn’t the case, because he could log in from my Mac and a PC.
I ran traceroute from Terminal to the server’s IP address and found that some links in the delivery chain were taking two or three seconds each, when normally the delay should be measured in milliseconds. The culprit turned out to be LogMeIn Hamachi, a VPN app that my son had installed to spoof his network location so that he could play on Minecraft’s US servers. All the network redirection this entails was adding so much delay that the Warcraft servers were timing out, making the game think the servers must be full!
