[Client] Client is busted for Mac.

I just wanted to play another match of this tilting game before getting off but I'm so annoyed by this recent bug. Every time I've tried launching the client (I have the new client) the window is covered with gibberish code and stuff and the entire screen is moved down diagonally so i can't see what I need to to even downgrade to the old client again. I manage to log every time which should fix it I thought. Everything is ruined. I still can't see the bottom right of the screen and there's a bunch of gibberish everywhere and even if I tried to play a match with the client being buggy and all I couldn't because of how the play button is also cut off from the window. I've tried redownloading the game but that doesn't do anything but waste my time. Please fix this Riot.
