OSX Spectate [Client] [Bug]

Hi, ever since about Patch 6.5 anytime I go to spectate a friends game I am stuck on a black screen, and thanks to someone who told me before when this happened to me in a game, I can just mash the enter button and force the loading screen. It still doesn't work 100% of the time, and when it does the spectate client tends to freeze and stop broadcasting the game for 25-30 seconds at a time. I don't know if anybody else has this issue but I thought I'd bring it up.
