Bug? Glitch? Who knows?

I use a mac. I had no troubles with it, ever since I started playing League. The only exception was lags, but thats due to my crapass internet.

This happened to me twice, but I'm sure it will happen again. I'm playing a 1v1 with a friend ( vs , and near the end of the game, I could not seem to do anything. I couldn't move my champ where I wanted it to, but I could attack what I wanted. At first, I thought it was my wireless mouse because I had some problems with it before. I start turning it on and off, but it did not work. I leveled up, and I tried to click on "+" button for an ability. It didn't work. Also, I tried to attack the turret. I kept on attacking it until I died. I thought it was like a one-time bug or something.

Later on, I played a game with , the game was going fine until I stopped clicking and attacking. Using a mac, I decided to quit as fast as possible, so I clicked "Command + Q", which led me to the choices of "Keep playing!" or "Leave Game." I couldn't click "Leave Game." Next, I couldn't type or do anything. I don't know why, but soon I could type into the chat. I told my team that i was glitching or something. However, I could use my abilities too, which is nice, but I couldn't see anything because the box of choices ("Leave Game" and Keep Playing!"). I started to rage a little, but then I was able to click on the "Leave Game." I reconnected and this problem did not occur throughout the whole game.

I do not know why this is happening, but I'd like to see Riot acting to fix. If you want some information about my computer, I will give them to you.
