Game Bug-DC

When I went into the game, I could play for the first few minutes. Then my screen froze and I couldn't even exit the game. I had to turn off my entire mac in order to get back in. Next, when I entered the game again, the game didn't even let me back into my game. It kept reloading the dc button over and over again, but each time I clicked it, nothing would happen and it would just reappear again after a certain amount of time. Hope you can solve the problem riot games. Please try your best to do it quickly so I can get back playing again. And fyi this isn't the first time it happened. It also happened to me another 2 times this week.
