Mac OS X - Game won't launch after patch 4.20, simply sits at a black screen
Hello,
Ever since patch 4.20, I have been completely unable to play a game. The out of game client works fine, and Team Builder/Champion Select also works fine, but when it's time for the loading screen to come up, my screen simply goes black and the only way out is CMD+OPT+ESC (the Mac equivalent of CTRL+ALT+DEL). If I try to reconnect, the same thing happens - instead of the loading screen, I sit at a black screen.
Restarting the out of game client, and rebooting the computer does nothing. I repaired my game client but it did not fix the problem either.
It has done this for several days. (And of course the new LeaverBuster launched at the same time as this patch which has broken my game :( )
