[CLIENT] MAC: Excessive load screen launch delay/freezing

At first I assumed this was an issue on my end, but after reinstalling three times and repairing twice, I've figured it might be something that's a client issue.

The load screen when launching the game from champion select doesn't actually begin until after the other champions load it, so I start loading in after everyone else is already in game. The worst part is, if this doesn't happen, my game freezes at the four minute mark (4:00 to 4:50) every game for about a minute to a minute and thirty seconds.

I don't know if this problem is mac specific, but none of my window user friends seem to encounter this issue.
