I just bought minecraft and every time i run it , it crashes. When i double click on its icon in the application folder nothing happens so i have to go into the contents folder to launch its jar file. After I login this is the crash report that keeps displaying.

I am running this on osx 10.8.2 (mountain lion) My specs are:

2.26 ghz intel core 2 duo, 8gb ram

---- Minecraft Crash Report ----
// Surprise! Haha. Well, this is awkward.

The version of LWJGL (Lightweight Java Game Library) that comes bundled with Minecraft is incompatible with the version of Java that you have installed.

  • If you have multiple versions installed, you can use Java Preferences (usually at /Applications/Utilities/Java Preferences.app) to change your system's default Java version.

  • You can upgrade LWJGL without too much difficult - download the most recent version and put it in your ~/Library/Application Support/minecraft/ folder, overwriting the old files and the natives folder.

  • If you don't want to upgrade LWJGL, you can downgrade Java until Minecraft works. Oracle maintains links to old versions on their site, though versions that are outdated enough will require signing up for an Oracle account before they'll give you the download link. FileHippo and OldVersion can help with that.

    Downgrading Java is an EXTREMELY bad idea - it opens your computer up to a variety of virus attacks, none of which you want :P Upgrading LWJGL is simple - just download the newest version and install it into the minecraft folder, replacing the current lwjgl files.

  • @Andrew And yet it is a functioning option that some people may prefer, especially if they're on a secure network or using an operating system like Mac OS that is nearly never the target of viruses, Java-based or otherwise. There's a reason why the conditional "if downgrading Java is undesirable..." is deliberately included. (I'd dispute the "extremely" part too, but that's not an argument I want to get into the details of.)

  • @SevenSidedDie Mac OS is definitely not never the target of viruses, it's just less common. Java-based viruses often work on both Macs and PCs equally, I think it was unclear that that might often be undesirable. I might swap your second and third answers, unless you object.

  • @Andrew Swapping them doesn't change the intent, and I do see the editorial difference, so that's fine!

All you have to do is when you open the launcher, select Options => Force Update
