So, I've been playing minecraft on my macbook pro for a while, but all of a sudden, the game has stopped launching. I mean, I can go to the launch screen, but when I click "play", it takes me to a new screen which is called game output. 
So, I was wondering if this happened to anyone else. I've already tried uninstalling and reinstalling, but that didn't work. The funny thing is, it works on my cousin's laptop, but not mine.
Any ideas?

When reinstalling, have you tried to remove your whole
.minecraftfolder? If you don't know what.minecraftfolder is, or where it is located at, then I recommend you remove it, it's located atC:\Users\~YourUsername~\AppData\Roamingand save your saves file on your desktop from the.minecraftfolder, now try reinstalling minecraft using theminecraft.msiinstaller of the official minecraft.net site, click me to get the installer no java is needed for this one, and will install itself automatically, once you've done that it should work fine, if not, please give me your log ofLauncher Log, which includes the errors for us to help fix your problem.
