Black loading screen mac client bug

Pretty messed up guys. I can start a discussion but can't reply to a thread? This doesn't make any sense. I just had this client crash and tell me I had to repair, this happened when it tried to launch the game into the loading splash screen. When the game, I guess repaired, it would only load to a black screen. Nothing else happened and I couldn't get reconnected to the match no matter what I tried. A quick google search lead me to a 2+ year old thread that said to hit the return key on the keyboard to get it to load. It worked. Why is there a bug this old in this game still? Why isn't this fixed? I can't even reply to that thread and tell them they fixed my issue.
