FIX THE MAC CLIENT

This is happening too often now for me where I get into a game and the first 15 minutes of the game are perfectly fine and normal. However, while there is no specific time this occurs, I get massive lag spikes, disconnections, crashes, etc. There are games at times, I don't even know who is attacking me. I just see my health go from 100% to 0. This, as you can imagine is infuriating and this would be fine and dandy if I was the only Mac user who has had these problems. But it's not just me, multiple people have complained about it in the last 3 months. Not to mention my Mac is brand new with only WoW and LoL installed. Maybe it's the new map or something cause this never happened before it came onto the Rift. But please Riot fix the Mac client.
