This is a repost of ticket number 204885. There was a misunderstanding and no one seemed to see my latest comment. They thought it was for optifine, but I failed to mention that it happened to the newest official minecraft version.

So I've seen this problem as solved on another ticket (175281), but there was nothing there to help me, so I'm creating this one to ask for help.

I have a mac and I installed minecraft last night. I opened it the first time and it worked fine, I then wanted to see if optifine would work so I installed java 8 and installed optifine as a version. Then when I try to launch it to play it, it would crash each time. So I tried to play the normal version, and the same thing would just happen. I've uninstalled java 8 and minecraft countless times and installed it again, I've tried different ways and I've asked for help elsewhere. 

This is the log that it's giving me;
