My minecraft won't load. I click on the Minecraft icon, and I get to the login screen. I log on and just a black screen shows, no mojang logo, no minecraft main menu. after the black screen is there for a few seconds, it crashes:

Quote from webrosc

try updating you LWJGL files with this
http://syfaro.net/bu...JGL_Updater.jar

i see its saying your files are modded, what mods are you using?

I am not using any mods. I had to reinstall my os because it crashed. Before when I had Minecraft installed, it was bug free and lag free. Since I reinstalled my os, minecraft just won't load. I will try you idea and see if it works.

I tried that also. I ran that LWJGL_Updater.jar. I then went into minecraft and it still did the same thing. I then just deleted the minecraft folder (I have a mac), opened up minecraft to reinstall the files. It still crashed. I ran the LWJGL_Update.jar, opened up minecraft, and it still did the same thing. Here is the thing that came up:

It can't find your OpenGL version, try updating your video drivers. (Make sure you make a system restore point before you do so)

Can you post some system specifications?

I am using a hackintosh, so I don't think i can update my video drivers.

Quote from webrosc

its still saying lwjgl 2.4.2

you may have to update the files manually http://www.minecraft...ls/Update_LWJGL

I did this and now minecraft just stays on the black screen. Doesn't crash just stays on the black screen

I got every thing working now. I just reinstalled mac and everything is just working. I have no idea why it was not working before. Thank you guys for all your help and effort toward my little problem!
