[client - mac] White screen of gg no re

On mac, (OS 10.9), the new client will completely stall out in a plain white frame either while attempting to launch the client for the first time, or as the client restarts after a game (close client in game setting selected). The application becomes completely unresponsive and must be force quit and restarted. Sometimes it can never be restarted without a full comp reboot as league never successfully launches and only shows the white screen.

I had this problem a few month ago, which is why I switched back to the legacy client. It sucks when you can play the game just fine on your computer except you cant even launch it.
