“League of Legends installer NA (1).dmg” is damaged and can’t be opened. You should move it to the Trash.

Chrome downloaded this file today at 5:26 PM from signup.na.leagueoflegends.com.

From what I read on forums there is an issue with some certificates or something in the installer file, I am guessing there was a patch today and those forgot to get updated as well.

Yes. Dualboot if you want to run games without them being broken disasters with crap performance.
