GAMEPLAY BUG ON MAC OS X YOSEMITE (10.10)
When I start a game, my cursor won't budge from the top of the screen... What I did is this:
right click league of legends icon, and select "open content" then open "content" folder, then open "LOL" folder, finally open "config" folder. Now you should see a document called "game.cfg" open it with textedit. Change "OSXMouseAcceleration=1" to "OSXMouseAcceleration=0" and change "WindowMode=0" to "WindowMode=1". Enter game again u can move ur cursor every directions but down. You can change to full screen if you want. BUT DO NOT ENABLE SOFTWARE MOUSE otherwise you need do all this again.

The thing is... Now i cannot move down like it says in the last part... (like... I move my cursor down the screen and it stops, moves up a bit, and the screen moved like 50 units or less... so I have to move down, up, down, up, down (or use down arrow key) to move down the screen, which can get pretty frustrating... It's hard to play some champs with camera always locked on, so..)
Also, now when I ping, the ping goes at the top of the screen (so i can only ping of being careful...)
I'm using a Macbook pro 15 inch early 2013, with these specs: 2,7 GHz intel core i7 (3740QM) 16 GB 1600 MHz DDR3 NVIDIA GeForce GT 650M 512 GB SSD
Since this was an issue on the beta of Yosemite (in july) and it hasn't been solved yet, I wish that you find a solution for all of us Mac users who upgraded (a bit fast?) for the new OS and don't wanna play windowed mode..
Thanks!!
