Hello, I just purchased Minecraft Java on my Apple Mac. I am unable to start the game as the launcher continues to crash. I have updated java on my mac to the most up to date. I have re downloaded the launcher, however those steps have not worked. 

Can someone please help I have googled solutions and cannot find any, also have tried to contact Mojong support and havent got a reply. Have also similar posts on these forums, those solutions dont work either. 

The error message I am receiving is "Process crashed with exit code 6" Below is the log of the start up.
