Exit Code 0 on Mac El Capitan. Game crashes after Launching the Game in the MC Launcher

Hello!

 

Wanted to install the game on the MacBook Air, which is my GFs PC.

And whenever i want to press launch on the Minecraft launcher, the game crashes instantly and i get the "Exit Code 0" error.

 

Can anybody help me?

 

PS: Yes i got the latest Java 8 version installed.
