League Client Crashing when champ select finishes

Tonight I played 3 games of league on my mac's new operating system; El Capitan. The computer itself runs smooth and I have had no issues. This includes in game and during champ select. So this means to me that league just needs to be updated with a simple fix to prevent the crash. I have to quit the league client and then reload league and rejoin the game. Which means after waiting about 5 minutes I am super behind and have let the enemy (in this case top ) laner free farm. It specifically happens right when the counter is done after the 10 secs and I get the rainbow circle of doom. I don't wanna stop playing league either so if you could solve this that would be amazing. I don't wanna stop league. Been playing for 3 years now. I apologize for any grammar or choppy sentences. I wasn't great at english.
