Entering game bug

Hi riot, so I play on a mac and i've been told by my friends that riot hasn't patched this bug yet, but anyways i can get pat champ select but when i'm supposed to see the loading screen my screen turn black i wait an hour or so come back and the screen is still black. I turn off my computer and turn it back on I open the league launcher then it says "unspecified error has occurred please check the logs for more information". Not only has this led to me being upset that i cant play the game but now i have leaver busters. Please reply with some sort of way to restore my league and sorry if i'm asking for too much but if there is a way to get rid of leaver busters then I would like to ask for that as well. Thank You ThexMatthewK
