unable to connect to main screen

I use a MacBook OS X Yosemite, and this bug has appeared several times before. If you watch the boards through this season, you must've noticed many other discussions about this issue.

Well, this is the bug: You fill in your password, and everything is still the same. But the main screen, that is supposed to load, does NOT. There appears a 'trying to reconnect' sign and it tells me that I have to check my internet connection. Well, i can tell you that my internet is 100% fine. I can see everything else: my friends playing, my profile, just the main screen and sometimes the clubs.

Weirdly this bug has appeared very often through this season, but Riot doesn't really seems to care about it. Even though many OS X Yosemite users have complained about it.

This bug appears mainly on OS X Yosemite devices, sometimes also on other Apple Inc. devices.

Someone pls help
