Getting a grey screen instead of the load-in for Mac

I currently am unable to play League at all. I can log into the client, select a game mode, and accept the queue; however, the loading screen for the game is entirely grey. If I click nothing happens, and I am unable to do anything whatsoever until I completely shut down and repower my mac. I tried to do the solution previously suggested within this forum ( but it failed again. If you don't want to click the link, it pretty much is changing the WindowMode=1 or WindowMode=2 to WindowMode=0 Does anyone know how to help? Thanks
