Minecraft Forums

Hey guys,
I've been having this problem where every time I go into my own server or even a public server, the game crashes when I try to either type in the chat or open my inventory. I am using a mac, Ive tried uninstalling minecraft and then installing it back again by deleting the bin folder and then downloading again. I still get the same problem. Ive looked at a bunch of forums and had no luck. Whenever it crashes, this is what comes up:

if you have any solutions please comment or leave a reply because this is really urgent. thanks for taking the time to read this post!!!

I've never seen that before, but I think you should try deleting your entire .minecraft folder and not just the bin. Sorry if this doesn't help.
