Basically, do I need to reinstall Java? I'm trying to avoid doing so because it looks insanely complicated. Plus I'm on Mac, which I'm not great at yet, so I'd like to bypass that if at all possible. I've tried everything else I know of; update LWJGL, force update a couple times, reinstall, update Java, and nothing has worked. It crashes when I open my inventory. Thanks for all your help. Let me know if you need more info.

I have had the same problem a couple times before, and im running on windows, so i just reinstalled java in all, it still was quite complicated to get java out and then back in. If you are able to in any way than try to reinstall java, it should not be too hard, it just takes some looking, and i did it, so yeah.

Only option i have:

-Reinstall Java

Look at the second "known issue".
If you already had updated lwjgl, then you have done it wrong, your log shows version 2.4.2, whereas the latest is 2.9.0

You can also try the new launcher, as it ships with the newer lwjgl.

• Mac/OSX: https://s3.amazonaws...r/Minecraft.dmg

To switch to 1.5.2, click on 'edit profile' and select release 1.5.2 from the 'use version' dropdown.

thanks, that solved the problem. much appreciated.
