mac client not opening [solved]

[solved]: i just clicked on "remove from dock", i just removed the League client icon from the Mac dock menu at the bottom of the screen, and now it works for some reason.

[original post]: every time i try to launch League on mac computer, i get the error message "league of legends quit unexpectedly" and the client never even appears on screen. this didn't happen yesterday, nor any previous day. i already tried rebooting the computer.
