Game won't let me reach Summoners Rift.

I have a mac. Ever since the new client came out, this bug would happen. Don't get me wrong, I really like the style and decoration of the client. So I would be able to reach champion select and i would choose a champ. then after the time ticked to zero, i would be brought to the loading screen. Every single time I play league (no matter the map), I would be linked to a screen showing the outlines of where the champions should be and their usernames, but everything else would be black. After possibly 5 minutes or so, theres a possibility that I will reach the game. But if I was able to reach Summoners rift, two to 5 minutes would have already passed and I would have a huge disadvantage. The other times, I would never even get to play the game that I desperately wanted to, and would sit in that black screen for 5-10 minutes until it finally said to me that you have disconnected. And the team would probably have remaked by then. Please fix this bug Riot! I am being forced to use my laptop all the time since it doesn't lag nearly as much there. I have accumulated quite a few leaver buster punishments as the failure to reach the game has accumulated. Thank you for your time![slayer-pantheon-thumbs]
