Mac client problems ( Too slow loading screen)

The Slooooow Loadingscreen on Mac LoL
The utterly ridiculously slow loading screen on Mac...
As shown in the above video, i am experiencing the same problem. There are many other mac client users who are going through it. The game starts when the time is already about in 1 min 33 secs. Moreover the loading screen takes too much time. Please resolve this issue as purchasing mac and then experiencing such problem is really annoying.
