Entire Mac Client
I find it hard to believe that riot is working on all these cool new features like the HUD and skins and all that while I can't play league on a mac. I can not play on a mac because if I pause the game, it freezes for at least 30 seconds. 25% of the time in load it I crash. If I tab out of league it just crashes tabbing back in. Sometimes the updates take up to 14 hours due to a patcher bug (While normally my downloads go at 2 mb/s). In 2 of the patches my Mac has denied League on the built in firewall not letting me log in. Sometimes in mid game it likes to just crash making me reboot the entire mac.
All of these have been happening on and off sine patch 5.10. I can't play ranked incase I crash. I can't play normals incase I have to wait the 20 minutes for leave buster since mac client is broken.
