I am having League of legends launching problems on mac... I followed all the steps... but I try opening it and it does the things shown in the images... Open the little banner at 6.5 Megs as it just adds megabytes onto it and just never opens... Help would be VERY appreciated!
What OS are you using? Did you delete the Prefs completely? (/Users/NAME/Library/Preferences/com.riotgames.leagueoflegends.launcher.plist and /Users/NAME/Library/Preferences/com.riotgames.leagueoflegends.lolPatcher.plist)
If the game just shows the banner then quits, delete the Pref files listed above and try again.
Restart Mac and Pram (on restart sound, hold Cmd+Option+P+R) wait for 2 tones then release keys. Then try to start league.
Else delete everything League, empty trash and reinstall.
